Using Linksys WRT54G2.

When copying files between computers on the wireless network, the internet is completely crippled and unusable.

I'm assuming because the file transfer rate is too high. Is there a way to limit it on the router? Alternatively bandwidth limiting software I can install?

Thank you

Are you talking about other computers on your network or the ones that are also involved in the file transfers? If you are talking about other computers not involved in the file transfers, are these wireless clients too?

Every computer on the network is affected in the same way. All the computers are connected via wireless.

You've confirmed my suspicions. Depending on the network traffic and how chatty the sessions are, you can get slow downs like this. Wireless works in a half duplex mode no matter if it is n, b, g, or a. When you do a what I presume as a Windows file copy, you are using CIFS which is extremely chatty. The easiest fix for this is to do your large file copies over a wired connection.

Thanks for your suggestion but unfortunately a wired connection isn't possible.

I've seen internet bandwidth limiting software - would this work for file transfer too?

You can try bandwidth limiting software. But I really think it's going to be a combination of issues here. One of them is bandwidth consumption. This is dependent on how large a transfer you are doing. The other is what I stated which is how chatty your wireless clients are on your wireless network. As I stated, all wireless schemes work on a half duplex principle. This means every client has to listen on the air waves to ensure it is clear to transmit. Because of the waiting and checking, this adds latency to the network comms. You don't have to have large bandwidth traffic in this scenario to cause a rapid slow down in your wireless network.
