There are 4 other PC's in the house all connected to the same wifi. These 4 PC's have been experiencing intermittent internet hangs and slowdowns, though the worst affected is laptop and the PC next to it.
After several calls and visits by Time Warner techs, we've come to establish that there is no problem with the router, cable modem, cable connection and so on. We also established through trial and error that shutting the lid on the affected laptop will slow the internet connection speed considerably.
Lid open, the laptop hits 55mbps download regularly on speedtest. When closed, it fluctuates from 8-12mbps. The remaining PC's in the house regularly hit 20-25mbps on speedtest and the network doesn't seem affected by the laptop lid position.
So we know the laptop lid being closed affects that laptop connection speed but so far I do not understand how it can affect the entire network? Or perhaps this is just a coincidence.
Right now I'm not sure what the next steps could be in order to fix this connectivity issue? I'm also unsure why the laptop gets 55mbps and the other 4 PC's on the network only get 25mbps? I'm currently in the process of leaving the laptop turned off and checking for connectivity issues on the other 4 PC's but because it's intermittent it is hard to tell for sure.
Does anyone have any advice, suggestions or answers?
