I recently had an electrical water heater installed in my utility room, which is located on the bottom (2nd floor) of my house. The old one, which was gas operated, was having ignition problems and needed to be replaced.
My router has always sat a foot away from the water heater, but ever since this new one was installed, I've been having issues keeping a steady wireless connection on the top floor. I think my router is experiencing interference.
If I open a webpage in Firefox while on the top floor, I only get a "Connecting" message on the tab... but if I walk a little closer to the vicinity of the router, the page will finally load. I used to get a solid connection from pretty far away, but now I'm lucky to get anything at all.
I've tried diagnosing the connection with Windows because I sometimes notice a yellow exclamation symbol in the taskbar, I can't remember the exact phrase of the issue it finds, other than a 'fix' resets the wireless card and returns the 3-4 wireless bars I had. As for the router, it's 3 months new and has been working fine up until recently.
I called Netgear support and had them help me change the channel of the wireless frequency. Unfortunately that only made the channel stronger, but didn't prevent the interference from going away.. unless I remove the water heater, which is just silly. Due to the short ethernet/internet cables that run into that utility room (I think my ISP had it installed that way), I'm not able to move the router to a different location.
I really need some advice on this one, because I'm honestly quite stuck.
