Hi, I've got an interesting problem. Up until 10 days ago, my WRT54G was working fine. Then it all changed. I noticed that whenever I went to download a large file (say over 5MB), the download would hang part way through. I reset all my network devices, tried a complete powerdown, bringing things up one at a time etc., but the problem persisted. Next I talked to my neighbours, and they are also having problems with their wireless networks - 2 x netgear, 1 x linksys, 1x belkin. So I fired up Net Stumbler, and looked at the connectivity / noise graphs. I noticed that all 5 of our networks become inaccessible for around 20 seconds every 1-3 minutes. Now I don't know enough to get any further than that, so I thought I'd ask if anyone else had ever seen any problem like this before? Thanks, James.
