Don't use a wireless.
When I do have a connection the signal strength is great.
As for the weather, here in Albuquerque, it's been great for the past 2 weeks, and I sometimes shut down my computer and or recycle the modem by unplugging.
I checked all my connections made sure their tight.
So I still think that Comcast has overloaded in my area, and I just get butted off line.
