There are three computers using wireless network cards to share printers and be in a workgroup together. The printers hang off of wired ports on the netgear wireless router. The wireless router, using a lan port, is also connected with a crossover cable to a DSL modem/router. The DHCP server on the wireless router is disabled so all dhcp requests are handled by the server on the DSL modem. Getting this far was a headache. If I cold boot the DSL modem, wireless router, and pcs in that order, everything is fine for a few minutes. Pc's can see the network neighborhood, printers, and cruise over the internet via the DSL connection. After about five minutes, the PCs loose connectivity to the internet. As a diagnostic tool, I brought in my laptop running linux. Quite accidently, since it doesn't have a wireless card, I discovered that if the linux machine is plugged into one of the four wired ports on the wireless router, it can ping the internet nonstop. I set it to ping once every ten seconds. I expected it to loose the connection the same time all of the wireless machines did, but it didn't. From the linux machine, pinging the ISPs DNS on the internet, I had an average round trip of 40-80ms (guess-damnit). I couldn't ping the DNS from any of the wireless PCs, so I had to settle for pinging the DSL modem. The average roundtrip from wireless pc - wireless router - cable - DSL modem: 186ms. And that isn't a guess after 50+ pings. So what gives? The wireless strength is excellent. The wireless PCs fail everytime after a few minutes, no matter what! Do I have to switch to a wired hub? Would turning off some protocols help - there aren't that many enabled? How would interferance show up - poor signal strength? The network neighborhoods seem to be working well enough. Is there a way to tell IE (and XP ping and networking in general) not to time out so quick? The other weird thing, once the internet connection has been lossed by the wireless PCs, it hasn't ever re-established. Any suggestions before I switch to wire?
