One computer using the Internet should not prevent another from using the Internet also, if the network is set up properly. How do you have your network set up? Please give us the following information:

What kind of connection to the Internet (DSL, cable modem, T1, something else)? Is it at a home or business? What is the make and model of modem (for example, Motorola Surfboard or DLink D300T)?
What is the make and model of the router connected to the modem?
Are your computers all connected to the router by a cable, or wireless signal? Do you have another hub or switch between the router and the computers? If so, please tell us its make and model.

Does this happen just with one computer, or with all of them? For instance, you download with FTP on computer A and computer B can't access the Internet. If you download with FTP on computer B, can computer A access the Internet?

How do you have your network set up?
i set up with set the setting in the moden (jz set the IP become assign by DHCP, set password n user name connect, and the type of connecton). and the hadrware for each computer. (newtwork card and wireless adapter)

What kind of connection to the Internet (DSL, cable modem, T1, something else)?
cable modem

Is it at a home or business?
home

What is the make and model of modem (for example, Motorola Surfboard or DLink D300T)?
motorola (SB5101i)

Are your computers all connected to the router by a cable, or wireless signal?
2 computer using cable and one computer using wireless

Do you have another hub or switch between the router and the computers?
ya... brand syslink(WRT54G)....

Does this happen just with one computer, or with all of them?
happened to all computer

you download with FTP on computer A and computer B can't access the Internet. If you download with FTP on computer B, can computer A access the Internet?
not....both also not.

if the network not problem then even with computer using P2P technology or download form FTP other will not affect rite (will not affect until cant loading web site)?

if all computer in the network didnot using any P2P technology or download from FTP, then the speed would fine. Problem occur when some one in network using P2P or donwload from FTP.

my network was not very big, jz 3 computer connect to.

isnt setting by ISP (to block P2P technology)???

I doubt that your ISP would block P2P (and if it did, it would block the P2P itself, not other computers at the same time). It certainly would not block FTP, so the fact that that causes other computers not to be able to access the Internet tells me that the problem is not a block by your ISP.

Therefore, I think the problem is with your router, the Linksys WRT54G, and perhaps how it's connected to the cable modem. First, let's make sure you have it set up correctly. You should have a cable going from its WAN port to the Motorola cable modem. Both of the computers using cables should be plugged into the Linksys (in any of the LAN ports, which are probably numbered 1-4); neither should be plugged into the Motorola modem. In the Linksys router's setup page, the Internet connection type should be set to either "Static IP" or "Obtain an IP automatically," not "PPPoE." Is this your setup, or are there differences?

While an FTP or P2P session is going on, can you browse the Internet on the _same_ computer?

Are you using encryption on the wireless computer? Does this problem happen with the two wired computers, or only when you use a wired computer and the wireless computer?

While an FTP or P2P session is going on, can you browse the Internet on the _same_ computer?
not (need refresh few time, maybe can)

Yes, "up to 4mbps" means that you don't always get the maximum speed. With a cable modem, you're sharing the connection with your neighbors, so if some of them are using the connection heavily, that will slow you down. But there can be any number of reasons for a delay loading a web page--it could be a problem with the server that is hosting the web site, or a glitch in the transmission process, or your own computer is running something in the background.

The fact that you're getting the same results when doing FTP and web browsing on a single computer is puzzling to me. Certainly it would be slower, but FTP (or P2P) shouldn't prevent you from web browsing.

About the only suggestion I have is to try connecting your computer directly to the cable modem. (You need to unplug the power from the cable modem after you disconnect the router, before plugging the computer in directly, so that the modem resets itself. When you switch back to the router, unplug the modem again.) Then try FTP and web browsing on that computer. Does it work with both, or does the web browsing still fail? If it works, then there's apparently a problem with the router. If it doesn't work, then I think you need to talk to your ISP. Don't talk to them about P2P; test it with FTP for them. (You can find big files to download at Microsoft's download site or other software companies that have demos.)

> u mean that if some one donwload using P2P or ftp, jz the computer(downlaod) will affect then other will not much affect?

What I am saying is that if you are downloading with FTP, or downloading/uploading with P2P, that will slow down anyone else who is using your Internet connection, whether they are on the same computer or a different one. Your connection has a maximum capacity of 2mbps, and an FTP download can use all of that. But the computer, the router, and the ISP's server are designed not to allow a single connection to take all the capacity, so web browsing should still work, but because it has to share the connection, it won't be as fast as it would if there were no FTP download at the same time.

If this is still happening with a single computer connected directly to the cable modem, then I think you should talk to your ISP. I don't think I can offer any more assistance. I'm sorry I couldn't resolve the problem. Good luck.
