Dutifully upgraded firmware and now I am experiencing problems connecting to devices on my Google Home smarthome network as well as connecting my wifi Samsung speakers to my wifi Samsung TV to enable "Q-Symphony.*
All of this was working just perfectly ok every prior firmware upgrade.
I needed to force the 2.4ghz WiFi connection to fix my Samsung woes (it used to all work fine at 5ghz) but my Google Home situation is maddening - some devices are longer available on the app while others are.
Thank you! I didn't realize that I could downgrade Firmware, which is great. Turns out, I was able to rectify the issue by changing the setting (I think it was "BSSID"?) that blinds the SSID to some devices. I am not on that network now so I can't see the setting in front of me, but that seems to have been the culprit.
Perhaps it was changed to default to "on" in this latest firmware update?
It may not be caused by the Randomized BSSID, since this does not hide the SSID. The WiFi BSSID will be randomly modified every time the device is started.
We need to check this issue further if you are available to do more test.
I understand that in theory BSSID shouldn't be the issue -- and it may not -- but after my upgrade about 1/2 of my smart devices stopped working on the 5ghz network (no wifi found) but would work on the 2.4ghz network. But when I turned off BSSID everything started working again on the 5ghz network!
I assume maybe the smart device that also records the BSSID. When it connecting to WiFi, in addition to check the SSID/Key, it may also verifying the BSSID.
In fact the firmware v4.6.x already has Randomized BSSID and enabled by default.
Does this issue not occur on v4.6.x?
You also mentioned that there is no problem connecting the smart devices to 2.4GHz WiFi with Randomized BSSID enabled?
Please PM me the issue syslog when the smart devices cannot connect to 5GHz WiFi and let me know the MAC address of the smart devices.
Hi. The GL-AXT1800 is in a part-time occupied location so I'm only there about once a week. I will PM you the syslog next time I have a 5GHz connection issue.
I do want to offer an update: the last time I was there, a few smart devices wouldn't connect (again) to the 5GHz network even though they were working fine when I had left the week before.
A reboot of the router fixed the issue. This may have actually been the solution last time as well -- I just happened to have disabled the BSSID prior to rebooting.
Still, it's quite confusing as to why these devices would get "lost" after being connected for about a week. Agreed?
I'd like to confirm the disconnection issue: If the client device is a PC or phone, can you see if the WiFi is connected but no network access, or the WiFi is already drop?
If don’t restart the router at that time, and click WiFi on the PC or phone to manually reconnect, does it work?
Yep, if the issue reproduced, please export the log and share with us.
I will do more tests when I'm there next, but when I was there yesterday, I found that more than half of my smart devices (mostly Google but also SmartThings) were no findable via Casting on the 5Ghz network. When I shifted my phone's wifi to connect to 2.4Ghz, those devices were available for casting to.
To answer your question, I've never had a problem actually accessing WiFi or internet access via WiFi via the router on my phone.
The issue appears to be limited to what devices are available on which band to "cast" to.
Make sense?
Let me know what other tests I can complete to help diagnose? Thanks.
It can be confirmed that GL firmware are not restricted the casting service on a certain WiFi band.
May I know are these casting devices unable to be searched by phones?
Please help collect the following information:
In GL GUI -> Clients, are they online? Try to SSH to router, ping the casting devices IP, is it reachable? I wonder if the WiFi connection of casting devices is normal or drop.
Connect the PC to the router 5G WiFi and ping the casting device IP. Is it reachable? If ping is reachable, means the casting device is connected to WiFi. At this time, check whether the phone can search for these casting devices and initiate casting to.
If do not restart the router, these casting devices cannot search (or connect) 5G WiFi to the router, right? If reboot the casting devices, can it reconnect the 5G WiFi?
