We're using 3 laptops wirelessly with a WRT54GS. One of the laptops only has a "B" only wireless card, so I've set the WRT54GS for "B" only. Our signal strength constantly drops to "Very Low" every 1/2 hour to the point where the connection attempts to "acquire the network signal" again. We find ourselves constantly repairing the connection. Sometimes a repair doesn't even work and we have to reset the WRT54GS by unplugging the power to it. What can improve on this situation? I'm considering getting external wireless cards or a range expander, but I don't know if those will really solve the problem. Please help.
