Mine is stuck on 149+153+157+161 (shows as 157 in the no longer accessible settings on the router). Only one close by neighbor has 5 Ghz equipment and it is using the same channels. I had manually set mine to 36+40+44+48 (36 in the router settings) quite some time back but now Comcast has decided they know better. My transfer rates have really suffered. I used to get 450 - 500 Mbps download on my phone Now it is 350 on 5 Ghz band. Similarly, my 2.4 Ghz channel is shared by almost everyone closer by now that I can not choose the one that is the best for my use. I had spent quite some time dtermining the best chanels for my location and assigning the various devices to the 2.4 Ghz band or the 5 Ghz band. Typically, thermostats, garage door openers, and similar devices that have no need for fast wifi were assigned to the 2.4 Ghz band and laptops were assigned to the 5 Ghz band. The assigment of devices to the bands is still ok but the speed on both bands is less than it could be. I despise it when a company assumes they know more than the end users. This needs to be fixed.

Update: After two days the XB7 is performing at about the same speed as the XB6 that it replaced. Netuptime Monitor showed that the internet had been continuously active so the modem was not reset nor power cycled. I have no idea why the performance improved.
Original Post: I just installed an XB7 to replace the XB6 that I had. The wifi is much slower than the XB6. Testing from the same locations, speedtest shows phone download speeds are about half as fast (130 Gbps with XB7 vs. 380 Gbps with XB6) and similarly about half as fast upload speeds (15 to 20 with XB7 vs. 41 with XB6). Download speeds using a laptop dropped from 240-300 to 130-150. Upload speeds on the laptop dropped from 41 to 15-25. All tests were using the 5 GHz wifi band. The ethernet connections have not suffered as much but vary more than when using the XB6. Download the XB7 varies from 900 to 940 when it used to be consistently 950 with the XB6. Upload with the XB7 is now 35 to 40 when it was always 41 with the XB6.
All of these speeds are after a Comcast representative provisioned the modem. I had to call Comcat since after it was first installed the upload speed for wired and wireless was a pitiful 6 Gbps.
Has anyone else experienced this? Should I just go back to the better performing XB6 or should I ask for another XB7?

I am having a similar problem getting the free xFi pods. I received a notification 2 days ago saying an assessment was finished and that as an xFi Advantage customer, I could get 3 free Pods. Today I logged into my Comcast account and found the same message about the free Pods. I clicked on the link and everything looked fine until a message popped up saying “Sorry contact Comcast.” I tried the link several times with the same result each time. I initiated a chat session where I wad told that Comcast never sent Pods for free. How can I get the Pods that I’m told on my account that I ca have?
