I've got a funny feeling this may be related to the large file transfer disconnects, as the behavior is similar. I've got a recently purchased WRT54GS v1.1 and flashed to the Linksys v3.37.6 firmware (though it had this problem with the firmware revision before as well). I also have a Airlink Plus APSUSB1 print server. I have two computers, connected by 802.11g to the router (using WPA-PSK TKIP). The print server connects by ethernet cable directly into the router, and I've manually assigned it to port 192.168.1.99 . The printer port on the computers connects by TCP/IP. The printer is an EPSON C82 (which is specifically listed as compatible with this print server). The problem is as follows, I will attempt to print a document (say 10 pages long). The printer will begin printing, everything looks good, text & graphics are printing as they should, then the printer will get to about the 3rd or 4th page (sometimes as far as the 7th or 8th page) and then suddenly, BOTH computers (including the one that had nothing to do with the printing) get disconnected from the wireless network, and the printer stops printing. After a few moments the computers will reconnect to the wireless network, and the computer that was printing will automatically attempt to continue the print, about HALF a page will print again, then both computers are AGAIN disconnected from the network, the print will error again, and the process will repeat itself over and over (attempt to print, disconnect, re-connect, attempt to print, disconnect, re-connect, etc.). Now the funny thing is, I have an old 802.11g router here (poor range and crappy firmware, I replaced it to get a better signal, which the Linksys did very nicely), when this print configuration used to be hooked up to it, everything worked great. I've been tweaking settings for a week now, tried different cabling, router settings, even separated the two as far as possible to reduce interference. Any ideas?
