I recently swapped out a Cisco Valet M10 for the Cisco E3000. The E3000 is supposed to have a stronger signal. But, I am still getting about the same performance from the E3000 as the M10. The signal strength changes, in no particular order, from very high to low to no signal at all within minutes without any physical change in locations. When I lose the signal, the network is gone from my Available Networks list and I can't reconnect. The router is on the second floor, the laptop is in the basement. A first floor laptop works fine. Why does the signal strength change so often, and is there a solution? Cisco says they have no range extender for the E3000. Cisco tech support is pretty lame. Thanks for any help

There are any number of things that can interfere with your wireless signal, particularly since you have several walls/floors between your router & PC. The type of structure, Is it brick? Timber? Is it metal framed? Where is the mains wiring situated in relation to the PC? What other wireless devices are present in the environment such as cordless phones, Garage door openers, Home security systems. Where are household appliances in relation to the wireless source/client? What else is in your neighborhood that might be interfering?

Sorry to tell but you are not likely to resolve your problem wirelessly.My suggestion would be to re-locate the router to the 1st floor and if that means running a Cat5e cable from level 2 to level 1 then so be it.
