@DevYangoz when you indicated that you're using Rogers XFinity 5G split band, is that to imply that you have set separate wifi network names and passphrases for the 2.4 and 5 Ghz band networks with the modem's Band Steering disabled? That would prevent the modem's Band Steering from flipping devices back and forth between the two networks as its sees fit, without any warning to the laptop user.
I think my first step would be to load Intel's Driver and Support Assistant which can be found here:
Intel® Driver & Support Assistant
Load that and run it to see if there are any updates to the wifi driver, or any other drivers. Updating those drivers would be your choice to make. Beware that Intel's drivers are ahead of Microsoft's updated drivers, so, if you run Intel's Driver and Support Assistant and update any of the drivers as indicated, and then ran the Microsoft updater, the Microsoft Updater would most likely roll back the Intel Drivers to the previous Microsoft "aware" drivers. For that reason I'll run the Intel Driver and Support Assistant after any Microsoft updates are completed.
After any Intel wifi updates and reboot, I'd try to determine if the laptop is able to see your 5 Ghz network and any other networks that are running nearby. If you can see the 2.4 Ghz network and nearby 2.4 Ghz networks, but can see any 5 Ghz networks, that would imply that there is an issue with the 5 Ghz antenna or the wifi adapter itself. IF all of your other devices can see your 5 Ghz network and other 5 Ghz networks nearby, that would back up the observation that there is an issue with the laptop's wifi card or the 5 Ghz antenna.
Have a look at the following wifi cards:
In each case, near the very top of the card are antenna connector points labeled 1 and 2. Those connectors are used to connect to the antenna. The antenna itself are either buried in the body of the laptop, running straight out from the connectors, or possibly directed upwards so that they tuck in behind the screen.
If you were able to take the bottom casing off of the laptop you would probably see the wifi adapter sitting near the side of the laptop that sits near the laptop hinges. You could visually inspect the adapter to ensure that its sitting where it is supposed to sit. Those cards are normally screwed in place with a single screw, so, it should not have gone anywhere, but, fwiw, if you can access the laptop, I'd unscrew the card, pull it out of place slightly and push it back in, hopefully to remove any oxidation on the connector itself.
I'd also consider swapping antenna to see if the issue travels from the 5 Ghz side to the 2.4 Ghz side. If the issue stays with the 5 Ghz side, I'd replace the wifi card.
If you drill down into the Control Panel -> Device Manager -> Network Adapters, you should be able to determine the wifi card details for that wifi card and go looking for a replacement card.
Now, fwiw it might be possible to upgrade that card to one that runs 6 Ghz networks. That depends on HP and whether or not HP whitelists the laptop components, so that only the designed components will let the laptop boot properly. That used to be an issue a few years ago, but, it hasn't been discussed for quite a while now. If you peruse thru an HP forum, and I'm assuming that there is one, you might be able to find a few posts on replacing the wifi card in your laptop and you might also be able to find problem posts such as yours. I think thats one of the first things I'd do, update the drivers if required and then search for any posts that might exist on the HP forum for your laptop (again, assuming that there is a separate laptop forum.)
More food for thought, check any existing HP forum, and also check the Comcast Xfinity forum to see if anyone else has run into issues with an HP or exact HP laptop that you have, or run into issues with the wifi card that you have in your laptop. That might take some searching around within the Xfinity forum: https://forums.xfinity.com/
I know that @-G- has run into issues with drivers so he may have more comments for you on that issue.
Can you check the Device Manager and post the model number of the wifi card?
Fwiw, here's Rogers modem lineup at the moment:
https://www.rogers.com/support/internet/setup-install
And .... here is a Shaw page that shows the comparison between the three XBx modems, XB6, XB7, and XB8.
What modem do you currently have?
Just thinking aloud, I'm assuming that the modem is running 802.11ax as part of an 802.11 n,ac,ax wifi mode, and possibly running WPA3 for security. I'm wondering it the wifi card is 802.11ax and WPA3 capable? if not, either one of those might be causing a problem.
OK, hope this provides some food for thought.
@DevYangoz this almost sounds like a heat problem. Have you ever taken off the bottom casing to inspect and clean out the cooling fans and back ducts?
Is this your gaming laptop? https://www.youtube.com/watch?v=cPcjFump_1Q
If so, have a look at minute 6:20 of the video where the reviewer shows how to take off the bottom casing and shows the internal components under the case. The wifi card is on the left hand side of laptop. Its not anywhere near the cooling fan or ducting, so, that begs the question as to whether or not its beginning to fail due to internal overheating.
If this is your laptop, it doesn't look terribly difficult to remove the bottom casing to see if there's anything obvious that might be affecting the wifi card.
Fwiw, our son has an older Asus gaming laptop and every once is a while he will take the bottom case off and clean out the fans and cooling ducts.
Beyond that I'd consider the following:
1. Remove all wifi network profiles from the laptop;
2. Uninstall the wifi card, reboot the laptop and then reinstall the bluetooth and wifi drivers with already downloaded Intel driver install files.
3. Reconnect the wifi to your network to see what happens.
Have a look at step two to download the bluetooth and wifi driver files first, then return to step one, just below:
1. To remove the wifi network profiles, have a look at the following page:
that led to the following link:
https://www.sordum.org/14327/network-profile-name-changer-v1-4/
The download link further down on the page will download a zipped file that contains two executables: NetPnc.exe and NetPnc_x64.exe. I ran the NetPnc_x64.exe on my desktop to see what it picks up, and yup, there are a number of network profiles that I can delete. So, it looks like this is an easy way to delete any and all network profiles off of your laptop. At this point, I'd go ahead and delete all wifi profiles. You can also choose to delete any ethernet profiles that might be there as well. The profiles accumulate over time. Later on, when you restart the laptop and connect to your ethernet and / or wifi network, Windows should simply create new profiles as necessary.
2. Uninstall and reinstall the wifi card. I ran into an interesting post late last night to do just that:
https://community.intel.com/t5/Wireless/Wifi-driver-AX201-not-working/m-p/1377626
Have a look at that page. Download the driver files. Don't do anything else other than downloading the files, and when you have them stored somewhere, return to step one above to delete the wifi profiles first, then carry on with the list as shown to uninstall the wifi card and all of its drivers, reboot and then install the current drivers from the downloaded files. Its possible that Windows might have some old driver stored somewhere, but, hopefully, when you uninstall the wifi card, that process will remove all of the old drivers.
3. When all of this is done, reconnect to your ethernet and then wifi networks.
Run the laptop on 5 Ghz wifi to see if you can recreate the slow performance. If that happens, and you haven't taken off the bottom cover to check the fans and cooling ducts, then its time to tackle this one.
At the end of the day, if none of this helps, then I'd replace the card, but I'd replace it with a same size wifi card that does Wifi 6E (6 Ghz). Apparently the Intel Wifi 6E cards will only run on Windows, not Linux or Ubuntu. If you go down that path, find a Wifi 6E card that fits and then before you order it, check Intel's site to ensure that there is a Wifi and Bluetooth driver available for that card. You would follow the same procedure to uninstall the current wifi card, then shut down the laptop, replace the card, reboot the laptop and install the Wifi and Bluetooth driver. Download the Wifi and Bluetooth drivers before you start the uninstall procedure.
Hope this helps ......
@DevYangoz in all of your interaction with Tech Support, has the modem ever been replaced?
When you have time, can you log into your modem and navigate to Gateway >> Connection >> Rogers Network. On that page you should see three data tables at the bottom of the page, Downstream, Upstream and CM Error Codewords. Please copy those tables and paste them in to a post. To copy the tables, one at a time, place your curser just ahead of the first character in the table. Hold down the shift key and scroll down and to the right until the curser is sitting just after the last character in the table. Release the shift key and with the data still selected, use Ctrl c to copy the data. In a new post, use Ctrl v to paste in the data. Please do that for all three tables. You can use the keyboard arrow keys to scroll down and to the right to the end of the table. When you paste the data into a post, since the tables are all horizontal, the forum software will automatically generate a scroll bar at the bottom of the post so that people who are looking at your post can scroll right to see all of the data.
If you have a signal level issue, the modem performance can drop off of a cliff, and, rebooting the modem will temporarily bring the modem signal levels back into an acceptable range, until the signal levels degrade once again. Now, if the modem drops off line on its own, that's a definite signal that there is in fact a signal level problem. If the modem is operating in a degraded state in terms of its data rate, then that issue should affect all of the modem output paths, Ethernet, 2.4 Ghz and 5 Ghz. Its very strange that at a time where the laptop 5 Ghz falls offline, that a modem reboot appears to resolve the issue. Its possible that the modem wifi controller is failing, which is brought back into a operational state with a reboot, but, as you indicated, I think, when the laptop falls offline, your phone and other devices keep working.
So, its one or the other, the modem's wifi controller, or the laptop's wifi card. But, I'd like to see the signal levels at a time when both modem and laptop are working, and when the laptop 5 Ghz fails.
Have you ever placed your hand near or above the modem to see if its overheating? It should be sitting in an open location so that it has adequate ventilation.
@DevYangoz your second post worked. Those numbers aren't too bad. The downstream signal levels are a little high, but, that shouldn't cause any issues. I'm just being picky about them. The upstream levels are ok as well. I'd like to see them no higher than 40 dBmV, but again, that's my preference. There are very few uncorrectable errors, with three channels showing correctable errors. Channel 23 is interesting. I wonder if that is because of RF interference from some outside source? The OFDM errors are typical.
So, if you replace the modem that leaves two possibilities: 1. Some very strange issue with your account that just affects the laptop, or 2. Some issue with the laptop wifi card that is causing it to fail after running for a short time.
It might be time to take the bottom casing off of the laptop so see if anything is evident in a visual inspection.
