Upload Speeds

5 days ago we switched from 1300 Mbps speeds on our own Arris S33 TO the XB8 Xfi Complete Gigx2 plan.

Our download speeds directly from the Xfi router via Ethernet to a desktop via the 2.5 Port are around 800-1200 Mbps.

However, our upload speeds never exceed 10 Mbps. They spend 99% of the time under 5 Mbps. 

Tried calling. Can't reach anyone.

Tried chat, my agent changed 8 times during a 4 hour period of me trying to get help. By time one would start some steps, they'd vanish, a new one would appear and we'd restart the process, then it would keep happening just like that. After 4 hrs I gave up.

Averaging 3-4 Mbps upload speeds is unacceptable. I've tried direct Ethernet from XB8 to desktop, I've tried a switch, I've tried the XB8 in bridge mode and used our Decos wifi, I tried wifi direct from the XB8. I reset the device at least 20 times over the last 5 days. Nothing is working to improve upload speeds.

I'm using Cat 6 and 7 Ethernet cables.

Did everything and STILL an issue with the Upload Speeds. Just a reminder, I've reconnected and refreshed this XB8 over 50 times. I've tried it in Bridge Mode. I've tried it as a Router. I've tried other routers with speeds that exceed the XB8. I've tried Ethernet. I've tried Wifi. The Download Speeds are always good, but the Upload speeds NEVER exceed 10mbps and 99% of the time they are below 5 Mbps.  Screenshot attached.

I’m very sorry for this experience with the decrease in speed @user_rbr84 . I'd like to ask you some questions to narrow down the solution to this issue. Could you please send our team a direct message with your full name and full address? To send a direct message:

1. In the top right corner, you'll see a little chat icon near the bell icon. Click the direct message icon

2. Click the "New message" (pencil and paper) icon

3. In the 'To' line, type "Xfinity Support" there. A drop-down list appears. Select "Xfinity Support" from that list (an "Xfinity Support" graphic replaces the "To:" line)

4. Type your message in the text area near the bottom of the window

5. Press Enter to send it. An official employee, such as myself or whoever is first available, will respond. Thanks!
