Hello,
I have a problem with my wired connection on a C7100V. I've reset all Network Adapters and talked to my ISP (Xfinity) for hours yesterday trying resolve the issue. They said it was the modem, so here I am asking you fine people for help. I attempted to find the answer without writing one of these but failed to find an answer.

2. No the issue does not happen on my Phone over wifi. I turn off Cell data and get speeds close to 300. I have also tried to use the wifi on my computer to by pass the wire to see if that helps. It does not... Which made me think it was a setting on my PC so I reset all Network Adapters and it's not any better. Right now i'm receiving speeds under 1MB and upload just over 1MB wired. Computer is brand new just like everything else.
3. I pay for 1GB I would be happy with anything over 100 as it's just me using it. I know i should down size and I might.
4. Speeds Wired Under 1MB upload and just over 1MB download. Wifi speeds on phone with DATA off are over 300MB
5. No splitters or anything between the wall and my router. Coax is connected firmly on both ends. I receive the speeds acceptable on phone so i'm assuming it's the modem or the PC.
