I have a Linksys E1000 running on the latest firmware available from the Cisco website. When my main PC (Windows 7 64Bit SP1) which is connected with a ethernet cable is running the wireless speed is great for all my connected devices. (Android/Apple phones, tablets, family PC, etc). But when I shut down my main PC the wireless speed drops to the point where it can take 3-5 mins for google.com to load up. The wireless connection is still showing as strong, just the speed isn't there anymore. If I were to turn my PC back on, everything will load up almost instantly and be back to normal. I've tried reinstalling the router, resetting it all back to default settings and re configuring it but I've had no luck in solving this. I've come to a dead end at trying to solve this, and thus I've come here in hopes someone has had a similar issue before and might know how to solve it.
