Well, I'm going to give up and live with it. A previous thread did not offer any solutions, so I'll try once more.

System: cobbled together 5 years ago so old-ish: AMD Athlon, 512 Gb RAM. Linksys WUSB54GC with Ubuntu 8.04 (driver: rt73usb). Wireless network is WEP protected (old router... ) Oh and I'm in the basement with the router two floors up so the connection is so-so (generally ~60%).

Problem: wireless internet will connect but after a while, disconnect, then reconnect. This gets progressively worse as the computer is on for longer. Eventually, the connection is very very slow or not there at all!

Diagnostics: often ping will not work (to router or internet) but ifconfig/iwconfig give an IP address and connection to the network. Some websites seem worse than others, gmail is often bad.

Attempted solutions: manual connection does not work, I seem to need roaming mode. Ndiswrapper with driver from Windows CD was no better. Tried to compile a new driver using rt73, didn't work. Wicd did not help other.

Further information: my dmesg shows repeated joining attempts, all quite weird. It's shown below.

Extract from dmesg:
