Hi, all. I've got a WRT54GS, version 2.0. The basic probem is when I try to push a high-speed connection (i.e., copying folders of files, a big ISO, etc.) from LAN <--> Wireless. When I do that, the copy option will start, it will run for about 10-20 seconds, the data throughput will stop, thing will pause for 30-60 seconds, then I get a Windows error saying "network name not found". I've tried all the things below on both Linksys as well as Sveasoft firmware: - This is not the case when I go Wireless <--> Internet, but I think that is because my max speed there is 3.0 mb. - Lower speed connections from Wireless <--> LAN work fine. I can run a remote terminal all day long and it won't get disconnected. - This happens from both a Cisco 340 wireless card working at 11 mb and an Intel card working at 54 mb. - It happens on any channel I set the router to work. - It happens when I'm running 128 bit WEP as well as in the clear. - It occurs when the wireless clients are bridged onto the LAN as well as when they're routed (I hook up the WAN port on the router onto the LAN switch). - It will happen even if I connect the linksys's WAN connection directly off my 2003 server so I eliminate any problems I've got on the LAN side: . (2003 Server) <--> Linksys <--> Wireless <--> (Cisco or Intel card) - It happens when I set the router to be in b-only, g-only and mixed modes. - I still happens after I've replaced the linksys hardware with a new WRT54GS. - I"ve got a copy of Airopeek, and a trace of the connection shows Wireless Transmission retries, lots of data rate changes, TCP invalid checksums and several CRC errors. - It occurs when I have multiple wireless clients as well as only one wireless client running. - It still occurs (even the frame errors) when I unplug the 2.4 ghz phones and take out the batteries. - Wireless <--> Wireless connections seem to be able to work fine, even if I am copying from a "b'" client to a "g" client. - It still happens when I drop the MTU down to 1400. - The problem doesn't happen when I turn off the linksys and bring my old Cisco access point, so it doesn't seem to be interference (at least on the "B" frequencies). Any thoughts here? Is anyone else running into this kind of problem? I'm going nuts! The Linksys tech, and his supervisor, sounded like the were only trained to read out of the FAQ database and couldn't understand half the things I've done to try to troubleshoot this.
