4, in the "options" menu uncheck "show features" and "Plus information", close and re run Utorrent will find ads disappeared.

Installation tutorial

1, in the download and unzip, double-click the Portable.exe operation, as shown in the figure, no need to install software green, can be extracted using the interface shown in Figure

Using the tutorial

When you first open the Torrent, you will see the Torrent installation guide. As mentioned in the wizard, follow the simple instructions will help you choose the best settings for the Internet connection.

In the first part, you will be asked to choose your upload speed from the drop-down menu. If you do not know this information, you can choose from the location of your most recent position to test the speed of the Internet connection, and then click the dialog box at the bottom of the "test" button. When you are running the test, please make sure that in addition to the testing you do not use Internet connection. If there are other computers on your network, please run the test before disconnecting them or shut them. Repeatedly running the test, the average upload speed and get the test given in. The speed test, Torrent will automatically try to configure settings according to the test results. If you like, you can manually select the connection upload rate from the drop-down menu, but please pay attention to the difference between bits and bytes, the speed usually Kbps (kilobits per second) should not be given. With KiB / S (kilobits per second) confusion. In addition, due to factors beyond your control, the 100% test may not be accurate, so if the closest option than you receive in the test to the high point (may reduce 10%), then it is usually safe. If the difference is greater than this value, the best choice for low option and manually set the correct upload speed. Don't try to choose higher than speed tests indicating choices, I hope it can help you faster download, because it does not, and may ultimately damage your speed.

In part II, the first display installation guide when you randomly select a port, but you can change the use of the free port. Or, the port is set to 0 to Torrent to provide you want to choose a random port in the confirmation after the change. Select the port, left click the "test run" to check if the port is open. Torrent is an open port for incoming connection is very important. If you encounter a problem to open the port, please continue reading port forwarding guide.

Complete all configuration, click the "save and close to complete! If no need to return to this wizard to change for any reason, you can select "options" in Torrent, and then select the installation wizard... "(or press Ctrl + G) to access it. Or, you can in the status bar state left click the network icon.

Correct some settings
If you manually select the connection upload speed, and found in the Setup Guide in the type of connection must be rounded, it should adjust the upload speed limit to additional upload speed to take advantage of your own. Divided by the average upload speed you get in to accept the test of 10, then the five homes to the nearest integer. Now use this number to calculate your upload rate as the world's largest.

Test your configuration
The seed does not necessarily guarantee speed, so you can't pick out any random seed, and expect to be able to correct the test speed. Fortunately, there are many kinds of seeds, they are made by sitting in a fast broadband connection on the computer forever planted. Try a torrent of test to test your configuration!

If the configuration is correct, Torrent should be able to do not have too big difficulties, through these tests, the maximum speed of the most commonly used Internet connection. Because of these seeds only used to test the connection speed, so whenever you finish the test, can be deleted. Please remember, the speed does not mean you are experiencing every torrent download speed.

ISP interference
Some Internet service providers (ISP) to prevent or limit the BitTorrent connection, because the number of people using BitTorrent number, it will produce high bandwidth. Protocol encryption via hidden connection is a BitTorrent connection in the attack against the media. Some ISP can not be connected to any other random encryption data to distinguish, so they cannot be labeled as BitTorrent connection, and therefore can not prevent or limit it as BitTorrent connection. In general, no harm in here
Port forwarding
A large part of the time, users complained that the Torrent speed is not fast. This sometimes becomes a problem of individual torrent (for example, the lack of high-quality seeds, but the user does not allow incoming) is also possible connection to his computer, and therefore can not maximize the capacity of Torrent Connected to peers with this torrent. Because Torrent can freely connect to other nodes, so the Torrent had the best effect, thus to reduce or prevent access to other nodes will adversely affect the user is expected to achieve download speed.

Cannot accept incoming connections means that your computer is in the state of the firewall. In Torrent, if you can not get a green network status icon on the long time transmission of different seeds, then you may be in a state of firewall.

Why is the firewall is bad
Many firewall users found myself thinking: "Hey, I got a firewall restrictions, but I still can transfer files, so that means I'm okay!" They don't realize is that the firewall does not necessarily mean that you cannot download, because the firewall users can still set up the outgoing connections, connect to the peers in this way data transmission. While this is true, but that only you. This means that if other people try to establish a connection with you, try will be blocked by the firewall.

Then you must be aware that you may not only the firewall user group. Because firewall users can only outgoing connections, and cannot accept incoming connections, so they cannot connect to each other (firewall users) is very natural. In the fire state, can not only reduce the potential speed is not the firewall could reach, but also means that you use to other peer groups in very limited. Because the number of firewall users can connect the less, so they to the source of the data is less. In addition, because they can not accept incoming connections, so others will not connect to them, so they will lose more attention. In essence, not in the firewall state counterparts have more data sources may be connected.

You will get rid of the firewall state does not mean that you must get rid of the firewall. The only requirement is that you allow your hope is not application blocks to listen to what they want through the firewall port, also known as port forwarding. For Torrent, you need to set the firewall to allow Torrent listener port connection settings in the preferences.

Although this may sound like a security risk in your firewall poke a hole, but that is not the case. If no application listens to open ports in the firewall, then any incoming connections on the port will be ignored. If the application is listening, the security depends on the application. Unless completely remote attack Torrent the current version has a known, it will destroy the security settings of your computer, or on the firewall for Torrent to open the port without risk.

Personal firewall in port forwarding software
Now, people in their personal firewall software installed on the computer is not uncommon. Although applications many people simply allow them to identify the access to the Internet, but usually this is not enough, because the firewall may continue to stop the application allows try listening to the port. Therefore, you may need to create specific firewall rules, in order to make Torrent work in the installation of a personal firewall on the computer software. You should follow the general rule of thumb is that you must allow the connection set in preferences of the incoming TCP listening port and UDP connection. Because you are forwarding specific ports in the firewall, so don't let each startup Torrent listening port randomization.

Because of the personal firewall software available variety, thus unable to provide specific instructions for each product. Nevertheless, Torrent still has a dedicated firewall can automatically create firewall rules, that is the Windows firewall. The options that you are running at least installed Service Pack 2 (SP2) or Windows XP update, and enable a firewall.
Forwarding router in port
With the widespread broadband become people access to the Internet, and computers in every family has become a common sight, routers are usually used in home computers on the network sharing broadband connection. Even if computer is not in a broadband connection, ISP router also provides for its use often for its customers. Many people don't realize is that the router itself like firewall, even if your firewall software is properly configured, in no configuration, usually will make your computer by firewall restrictions.

UPnP and NAT port mapping protocol
As with personal firewall software, there are a variety of available routers, and because of the huge number, so in this user manual is not possible for each router contains the port forwarding instructions. Fortunately, many routers support UPnP (UPnP) or NAT port mapping protocol (NAT-PMP), allowing Torrent to open the port automatically without user intervention on the router, and then close the port in the port after use. These used to automatically inform the router port Zero Configuration Protocol problem is that they may not be all routers, and may contain different / incompatible protocols in many routers. By default, UPnP and Torrent in NAT-PMP enabled. If you find that you are still in the firewall state, then this may mean that your router does not support the two protocols, including the implementation of Torrent or use and is not compatible with the implementation. If this is the case, it is recommended that you disable these functions in Torrent, set a static IP and manually forwarding your port.

Set static IP
In most routers, connected to the computer network IP address is available from the router through the Dynamic Host Configuration Protocol (DHCP) selected in the selection of the IP address pool. The key word here is "dynamic", because it shows that the IP address of each computer is available according to the router IP address pool is still available in real-time IP address allocation. While maintaining its LAN IP address some people are lucky and long time, but this is not guaranteed under DHCP. Therefore, port forwarding rules may one day in the rulemaking will flow through a particular port forwarding to the LAN IP address on a particular computer, but it may be another day to stop working because of the particular computer LAN IP The address may have changed. Some routers (especially Linksys router) even do not want to be forwarded to the LAN port IP address in the DHCP IP range of computers. For these reasons, before moving to the port forwarding manual on the router, it is necessary to set a static IP address for your computer (the best in DHCP range).

Please note that the static IP refers to a static LAN IP, with WAN IP different and not related. LAN IP address of your computer is your location in the network, but in addition to other computers in the network, no one can see. Your WAN IP address is outside of a network can see your IP address of the network, but does not display the internal IP address allocation on the LAN, the LAN may contain multiple computers, each computer (NATURAL) has its own LAN IP. For port forwarding set static IP, your WAN IP will not be used for any and of no great importance, usually one step.

You can find the set of static instructions for IP in

Manual port forwarding
If you have a correct set of static IP, the last step is on your router for the actual port forwarding. To enter the router configuration, you can usually access the default gateway IP address in the Web browser (you may need before in some Web browser IP address additional http:// to make it work). From there, you need to find a way forward port or allow / managed "apps" through the firewall, which will be introduced by TCP and UDP in Torrent in the listening port connection on the computer is forwarded to the IP address, IP address is IP Your choice in the set static IP. The list can be found in many routers and forwarding instructions on port. Make sure the exact brand and model your router you know. If your router is not listed there, you should consult the router documentation, or search for a more detailed description of the Internet.

Test your configuration
Port forwarding, please check the port program using the installation manual "in step second to test whether the port has the right to open. If it is confirmed that port is open, then it's done! If not, then please read the descriptions above, and make sure you do not have any mistakes or skip a step. If you're sure
More port forwarding
Even after careful and laborious to follow before written all port forwarding instructions, you find out you still refuse to open the port. So what is the problem? The possibility of including (but not limited to):

ISP interference: some ISP deliberately known simply and prevent unauthorized port connection, in this case, in the state of your entire network firewall basically.
The Internet connection type: This is a striking example of the root of the problem is received by the wireless Internet connection (via satellite or similar way). The wireless connection client does not usually get WAN IP address, so permanently at the firewall status. In fact, you can't control any connection NAT will usually let you in an unblocked state. This connection is provided by the University, network administrators often prevent unauthorized connection with port.
Proxy service: after some ISP the user in a transparent proxy, so port checker may not correctly detect forwarding state. In this case, try a test torrent, let it run for a period of time. If the network status indicator light turns green, then everything can be properly configured. Nevertheless, the proxy server support people actually put on the back of the firewall firewall, therefore, if you are behind a firewall, you may still encounter problems.
Network hardware blocking: known certain modems will leave the computer in the firewall, even if they are technically not a router. A notorious example is the Motorola brand SurfBoard modem, you can read in the forum.
When it comes to port forwarding problem, user error is a very common problem, but the basic assumption of port forwarding all content in the guidelines have been carefully handled, and all of the above possibilities are not applicable, then the problem is likely to be another problem, namely double NAT. Any other problems listed above, if the user to operate according to the necessary steps described below, it can usually handle double NAT problem.

Double NAT
When your computer sits behind two or more routers, will double NAT. It is proved in the majority of double NAT case, the user has a special router, but they are not familiar with the circumstances provided by ISP with the function of modem router or firewall. In this case, the user simply forwarding router port to the computer, without a separate modem, this is the problem. The modem also plays the role of the router, so if the configuration is not correct, it means that the user is still in the state of the firewall, because special router user configuration did not actually in forwarding port to receive incoming connection, the reason is Everything is the outermost router modem blocking. Please note that this is a specific case of the problem at hand. In more serious cases, the user can have more than two routing equipment, according to the solution, correct the problem may become more difficult.

To remove or disable router
In the simplest case, the elimination of double NAT situation due to simply delete the extra router, or disable the routing function. The use of this method assumes that don't need external router running on the network. If that is not the case, so the only solution is to link port forward. By the method in this section, only one end router connected to the network, the router is connected to your computer actual router. Some examples are as follows:

You have a modem, it can act as a router, connected to the router modem, and then is connected to the router computer. In this case, you should disable the routing function in the modem, so you only special router as the only network router (which is connected to your comptuers router).
Do you have a modem, can act as a router, and two routers connected to all computers on the same router. In this case, you should disable the routing function of the modem, and delete is not connected to other computers routers.
As you can see, the general rule of thumb is you delete all the irrelevant router. However, you will notice that with the function of routing modem will never be removed - this is because the actual function for your modem is connected to the Internet is very important. In any case, to disable the modem router must be directly connected to the modem physical computer, and then access the modem configuration page. Before the actual disable routing function, you must ensure that your modem contains ISP login information. If so, then you have to go

Common problem
