Unlimited is the amount data measured on your usage not the speed of the data transmitted. Its classic over loaded node or its a crack somewhere in your line that is allowing egress to bring your noise level up on the modem. See modems talk to the head end through what the cable company calls forward and return paths. Obviously on different bandwidths/frequencies and these different frequencies has different noise level tolerances. If the weather is cool the cable contracts and when the day heats up the cable will expand exposing any cracks and leaks for ingress. This is sometimes where modems fall off because when the cable was cool it was closed, heats up it opens up and allows ingress. This causes modem drops, slow speeds and other issues. Just another thought.But I've got unlimited bandwidth bro... I shouldn't be limited at all.. I'm paying $90/monthly for my internet/tv-cable service combined.. its like some bundle package that lame ass Cox carries.
ATT or VIOS eh? I'll have too look into that.
I mean, I'm trying to start/run a business online as well... I actually had a customer contact me yesterday about one of my items for sale, and now.. I can't get the customer to contact me back, which means they've given up and probably don't want it! Which means I just lost a $200.00 fucking SALE!! Because of my ISP! Ugggghh...
