slow upload

For a bit now my upload speed has be unbearably slow at less than 1 mbps which is nowhere near what it used to be or is advertised to be. I have done all the trouble shooting I can from checking cables to restarting modem and router multiple times with no effect. Ethernet made no difference. Xfinitys AI was not helpful either. I'll by calling once I can but I wanted to see if I could get some help here. Thanks

I have an arris SB8200

A tech came out and it's been taken care of. There was something wrong with the cable and he fixed it. If someone reading this has had a similar issue and you have done the trouble shooting, schedule and appointment by calling xfinity customer service.

Good experience and I'm glad it's been fixed. Wish I had gotten the name of the tech so I could give him a shout out.

Update: Sometimes the upload speed goes back to normal for a brief time after a reset but it is not consistent.
