ASUS RT-AXE7800 Tri-Band WiFi 6E 6GHz Extendable Router w/ 2.5G Port Expired

Might as well wait for WFi 8 because by the time you're willing to pay for a 7 at the acceptable price for you, you'll probably post the exact same comment again.

You plan on paying $400+ for a wifi 7 router in the next 2 years? Cause you wont find a wifi 7 router under $200 till probably 1.5-2 years from now.

Yes it is a huge jump from wifi 6 and 6E but its not worth the wait for people who are on a budge but still want the best possible.

Comcast recently screwed over a lot of people by taking a bunch of modems off their previously "recommended" list and then not providing them with adequate provisioning.

I had the same issue with being on a 1Gbps plan. They did a free "upgrade" to 1.2Gbps and stopped provisioning my modem correctly. No amount of tech support could figure it out and they wouldn't admit they screwed up.

My speeds shot down to 400Mbps max, so I cancelled and got fiber rather than continue going in circles with them.

You need to call them up, have them check the provisioning, and confirm that the 8210 is still on the "supported" list for the plan you have.

Do a speed test (do NOT use their test or speedtest.net, as they have rigged those with prioritization tricks) by downloading a large file or using speedof.me (they aren't able to rig this one).

If your speeds are still terrible with the tech on the phone and they claim your signal is fine, have them send someone out to check the performance at the tap. Keep in mind the hardware they give the field guys is also somewhat rigged as it can do a lot of things your modem can't and isn't provisioned for any certain speed. It's going to give back maximum potential readings and most of the field guys will just slap the side of it and call it a day while looking cocky.

If your line to the premises is fine, you're back at square one with the modem, but now you have them doing a bunch of finger pointing at the modem being defective.

At this point, you can either try a different modem that they certify is "supported" or force them to downgrade your plan. If you play it right, you might get them to credit you for the difference on the months you've already paid for.
