1) Three windows computers (2 win10, 1 win11) accessing Guest network and can communicate to the internet but 2 of 3 can not connect to another device on the same network.
2) All computers can reach SOME devices but not all the same devices.
3) There are occasions when a computer CAN access the devices that it could not at a different occasion( after reboot computer, reboot network, power down, and have seen it inconsistently work after a /release /renew.)
4)Network has 2 wifi pucks and the network is fine per google home. All devices that can not be seen by the computers show up on google home networks.
4)From problem computers, devices cannot be pinged at all or respond "Destination host unreachable" (again inconsistent).
5) Using the device name and NSlookup on one of the problem computers:
*** homeportal can't find xxxxxxx: Non-existent domain
However, the IP address of the device is shown when ping xxxxxx is used.
How can I troubleshoot and resolve this issue?
Answered! Go to the Recommended Answer.
Update: Identified that troubled computers are on the 5G network of the same SSID but cannot connect. Forcing the wireless adapter to start on 2.4G network and connect to same SSID, all connection issues are resolved. The device that is being connected to is on the 5G network. The access point of the computer and the device are different.
So, I can never tell what is coming up on what AP at what speed but a 2.4G connection on the computer seems to resolve the issue.
Is there a configuration or setting that needs to be applied to the network? I believe that other device connections are being affected (Chromecast to Android phone, same network...). Maybe just a "bad" puck? At least I have a workaround.
Thanks for reaching out. I'm sorry to hear that you're having an issue with your devices communicating with other devices within your guest network. Does the computers stay on 2.4G? If not, do they still communicate with other devices when they switch to 5G?
Looking forward to your response.
Computers may switch or come up on either 2.4 or 5.0. It is curious that if/when the devices are on 2.4 and the computers are on 5GHz then most everything is "good". Other combinations are not so good. The inconsistency is due to computers that may come up on 2.4 or 5.0 or switch. I appreciate your asking. At least I feel I can identify when it is a network issue and reconnect to remedy the situation. Not ideal but better than just not knowing anything about what is going on.
I'm sorry to hear that you had to get rid of your Google Wifi points. We're sad to see you go. We hope we can make it up to you in the future. Let me know if there's anything else.
I have no other questions or concerns. I spent a lot of time trying to figure out the "root cause" and why things didn't work as I believe that they should. Always my first consideration was "I must be doing something wrong". Since removing the devices from the network, I have had Zero problems. This has been a real relief to me. It's unfortunate that I couldn't have been told that using this product based on my use case would be intolerable. Future considerations will be based on something other than "gee, it's Google, it must be good!". Hang in there and don't believe everything that you see on the internet... I do appreciate your responses.
