My computer itself is causing router interference!!!
I've been a U-verse customer for nearly 5 years now, and unfortunately it has geen a work in progress since the beginning. To make a long story short, after many, many, many tech visits, an assortment of new routers, etc., my outside line is clean, and my inside line is clean. The TV service is working reliably now, but the one sore spot that remains is internet connectivity. I pay for the 18 megabit service, but rarely do I get more than 6-4 reliably, and it would often gyrate so wildly that my wirelessly-connected devices (1 MacBook, 2 iPhones, 1 iPad & 2 Apple TVs) would continually drop their connections. The last service techician spent over 5 hours at my house running every test he could think of, but still no joy.
Out of total frustration, I began exploring this forum looking for answers. After reading this thread by SomeJoe7777
And seeing how such issues could be related to some sort of RF interference, I finally decided to do try some trouble shooting on my own.
I go to my breaker box & shut the whole house down. Since the router has a battery backup, it stays powered up. I pull up speedtest.net on my macbook (already wirelessly connected to the router) it shows 17 megabit max download. Aha. The game is afoot.
I methodically turn on every breaker, one by one, retesting again every step of the way. In the end, I isolated the interference to the room that is my home office, which contains the U-verse equiment, my computer (an iMac hard wired to the router by ethernet) and assorted peripherals. I disconnected all the peripherals, ditched the surge protector, plugged the computer directly into the outlet, and the interference remained. Then I shut off the iMac and tested again with the macbook. The test showed I was once again getting maximum speed.
Also reading how situations like this could be the result of "dirty power", electricity somehow feeding back into the line (the same line the router was using), I got an extension cord and connected the computer to one of my garage outlets. The result was the same. The iMac itself seemed to be what was interfering with the U-verse router. When I put the computer to sleep, full power. When I woke up it, interference.
So my problem is, and my request for help is, where do I go from here? My iMac is a 3-year-old 27 Inch 2.66 GHz Core i5 that runs just fine, so I wasn't looking to replace it, but I'm at a loss as how to resolve this issue. Would requesting that my router be relocated to another part of the house even help? Is there some way to shield the iMac from the router in such a way as to resolve the problem?
It's late on a Saturday night, so I haven't had a chance to even pose this to AT&T techincal support, but I'm guessing if I explained this situation, they'd end up telling me its my problem, not theirs. Anyone have any ideas?
