Dictation. Please excuse bad grimmer.I sympathize with you very much. I use Comcast over a wireless connection to my neighbor. And yes, I have for permission. The quality of my connection is marginal, yet sometimes I can watch entire movie on my
Roku to and not have any significant interruptions. Well, maybe a pause once in a while until it buffers some data.
What I mean to say is that I have a lot of trouble with my networking scheme and I've been fiddling with it for literally years. That doesn't seem to be any way one can guarantee a perfect connection. I have used AT&T DSL, Comcast cable, and digital path broadband. Of these, the digital path probably was the most reliable.
As far as I know this may be a common problem with many users. At least the ones that get perfect reception ever complain about it, obviously!
Here are some things that can interfere with your wireless reception. For one thing, one of your neighbors may be using the same channel as you do for wireless. In that case you will have to change your wireless to another channel to see if you get better results. Unfortunately, the tools that come with Windows don't seem to help for a much for taking channel numbers. So far the only way I have found to check the channels is by using some kind of third party software to tell me what channels are being used in my neighborhood.
Still, with a strong signal it should not make much difference. A possible problem is that Comcast may be doing something that they have not documented or explained clearly. For example, they put a limit on the number of devices you may have connected at one time. If they do that, and the you have not disconnected your other devices, then they will block your computer from getting into network untill you remove the other devices. So, how many devices do you have? You have a iPad, an iPhone, a Wee, and maybe a laptop?
Another source of possible trouble is from your microwave oven. But that would only happen while the microwave is actually running. Another possibility is the presence of a wireless mouse.
The fact that you do not have the problem in somebody else's house would suggest that there's something in your house that gem interferes with your wireless connection. However, you have mentioned that even with a wired network there are problems. So it is hard to generalize what is causing the problem. In some cases, very rare, a wireless device that gets into the network can interfere with the entire network. That usually means a serious defect in some piece of hardware. So you might consider replacing some of your Wi-Fi cards with external adapters. You would disable the built-in wireless card and use a USB dongle to pick up your wireless s signal.
One more thing, and I know I'm going to get flak on this, aren't you using USB 3.0? Because USB 3.0 can really mess up a wireless network. It has been documented elsewhere.
That's all I can think of now. As for me, I am used to resetting both my routers at least once a day just to keep the connection going. I am not sure why that makes a difference, but that's the way I have to cure the problem.
Hope this helps.
