XB7 vs XB6 initial performance disappointment

@adammusic22

What you did was a different test. That just tests to your device and not the gateway itself.

Correct, I said I didn't know of the test to the modem, and I showed what the tech got to the modem. I haven't tried the xfi test or wherever it is. It shows at best, I have never got a megabit out of the modem, hardwired, to 2 capable windows 10 desktops. And that wifi is cut in half to my fastest device, the only one capable of wifi6, that I suggest is a marketing ploy available to few devices. Meaning that it will be lower on all other devices such as a chromecast or Amazon firestick. And pointed out the 5ghz is weaker so a chromecast or firestick might default to the 2.4 rather than 5ghz since the 5ghz is weaker..

I go to Connect, then more, then xfinity speed test and it only allows for the speed to a device. I don't find a test to gateway. Certainly would be interesting to see though. As I read my last reply it seemed a bit pointed and certainly wasn't meant to be. Guess I fell into the mood of like talking to the recorded message when calling comcast. I couldn't find what others say can test to gateway, I get these results, and techs come out and say thats pretty good. Thanks for all the input though, I'll see if I can find that gateway test - maybe I missed an xfi update..

Wheres the gateway test in the ios xFi app?

It would be in the connect tab, but it seems it could vary by gateway firmware and if Comcast enables it on the account to be able to do it.

My excitement yesterday, regarding the restoration of the xFi option to monitor and measure the speed of the connection Comcast is delivering to my XB7 modem, has turned to the familiar frustration of not receiving the gigabit service level in a reliable fashion.
More than twice today I have been asked by the xFi app to restart the XB7 because of connection speeds that are lower than my premium speed tier.
The restarts did not alleviate the intermittent problem from recurring.
Maybe the XB7's ability to maintain a consistent gigabit connection is still a work in progress?

Oldmanriver1- I agree with you and disagree with nubsors statement. The test to the modem to verify plan speed is from the substation nodes and does a loop back speed and error check to the modem. That said, it was when I did them many years ago for a company connecting TV and radio stations to mainframes. I wouldn't think xfinity wants the customer to see those numbers, and get pics of it because they always tell me it looks good. Whatever device that initiates that test is irrelevant. It kicks off the test but isn't included in the test, unless its the test that I see and then it does run to the device. I checked all the screen options and never saw that I could do this test to the gateway,, I can only run to a device.. If I run through a router it drops the ethernet speed in half,, but straight from the xb7 it runs fine to my pcs with gigabit ethernet cards.. You have the s10+, I do too and thats all that can use the wifi6 for me. Its speed being wifi tested like 413 down and 40 up so wifi is not giving and won't give plan speeds. Plan speed is just to the modem. Modem drops it some for the gigabit it sure seems. Then cable quality and length and ethernet port and pc can drop the speed more, that I agree with nubsors. Wifi6 seems to eat battery more polling constantly too so I use 4glte at home. I fear doing any modem reset not knowing what may be set to reload but I should check my software version and see if it matches yours.

My measured speeds to the XB7 modem on the gigabit speed tier were generally good again on Sunday, after often being in the 600-800 range on Saturday.
But this Monday morning I have often been languishing in the 400-500 Mbps range according to the xFi app utility.
Each time the speed falls short, I am encouraged to reboot the modem. But that achieves nothing.
Finally the xFi app instructed that I needed to chat with an agent for a service appointment.
She was getting the same poor result, so a technician will be here tomorrow.

Measured speed provided from Comcast to the XB7 modem are excellent today so far.
I've had to set back my service appointment to the weekend.
It is significant to note that after many months with the unsatisfactory XB7 upgrade, this is the first time that a trouble ticket has been willingly issued based on the added leverage of the xFi app utility evidence that tends to suggest my gigabit connection speed is frequently unstable, often connecting in the 400 - 800 Mbps range, far below my gigabit speed tier.
Up until this point, no one at Comcast was willing to admit there was any problem.
Could a solution now be at hand?

Oldmanriver1 - I still can't find a gateway test so have to settle to my devices. Are you doing your test on ethernet to a pc or wifi to your s10+? I am 5 feet from my xb7. On my s10+ and 5ghz, xfi test gives me 518 down, I didnt run it for up. On speedtest.net I get 571 down and 35 up. Going to my ethernet pc xfi gives me 717 down, yet speedtest.net gives 944.8 down and 39.1 up. Then something I found in xfinity is myspeedcheck.net and it gives my pc 947.8 down and 41.9 up. I'm not too impressed with the xfi numbers. Here's a full link to the spellchecker I found:
myspeedcheck.net/speedtest/xfinity-internet-speed-test
Walking downstairs and my s10+ goes to 421 down and 41 up. Guess I'm about as close as they're going to get me to 1gigabit but would sure like that gateway test..

Here's how the Comcast speed to the modem test might look when your area receives the necessary updates.
Good luck.

Yes. It will here in Tennessee.
