I'm playing volunteer IT guy for a crew of archaeologists working in the field, and we have a bit of a problem... I have a Motorola SBV5120 cable modem connected to a D-Link WBR 2310 wireless router, and the wireless is as flaky as can be. Back home I had 3 PCs connected wirelessly with this router (on a DSL modem) and never had any issues. Now signal strength comes and goes seemingly at random. Occasionally, our PCs lose the signal entirely even if we are a foot away from the router. I have also had the signal strength show full, but have no connectivity; after a minute or two, turning off the airport, turning it back on and rebooting the browser brings it back.. As I said before, this happens regardless of range from the router. The router is set up with WPA encryption. At maximum I might have 6-7 PCs using the wifi, but the troubles seem to happen regardless of the number of people connected. Any suggestions?
