I might have a fix for some of you, it solved my problem at least. After a few days of email-talk with linksys i got a solution and tried it: First i downloaded this firmware: ftp://ftp.linksys.com/pub/network/WRT54GV2_3.01.3_US_code.exe Then after install, i did a 30 sec hard reset. Then i setup all my IP info. Linksys support told me also to change 2 fields in wireless / advanced wireless settings: Fragmentation Threshold: 2304 RTS Threshold: 2304 Save settings. And try if you get the same problems. I didn't. I can download big files, and use torrents with many connections without router reboot. I haven't tried wireless yet, but i suspect this firmware/settings combination could fix some problems you are having. Good luck!
