The 5G radio signal turn off sometimes

[adrianmak]

My router is AC87U, firmware 378.55

I used inssider to look around wifi devices. Only ME has a 5G signal router.

I found that the 5G signal turn off sometimes. I have to reboot the router to get it on again.

Have you tried Merlins latest code for the 87U ? If not you may want to give it a try it has a new driver for the 5G quantenna chip set that may resolve your 5Ghz issues.

Summary of changes since 378.55:

• Merged with Asus GPL 378_9177, which includes numerous fixes and tweaks, and improvements to the networkmap. This includes the newer Quantenna driver for the RT-AC87U, which resolves connectivity issues on the 5 GHz band, however it still causes some battery drain on that band. The only workaround is to revert to 378.55 if this is a problem for you.
• Support was added for the (unreleased yet) RT-AC88U. Thanks to Asus for providing a development sample.
• Enhancements to syslog handling. The default log level can now be configured (it used to be hardcoded to Emergency). This is especially useful to users who log to a remote syslog server.
• Editable entries for the DHCP static lease, virtual servers and prot triggers pages.
• Various component updates: miniupnpd, openvpn, dropbear and minidlna were updated to their latest versions.
• Various issues related to networkmap were resolved, especially handling of long hostnames.
• You can now configure up to five separate OpenVPN clients, to match Asus's stock FW.
• Numerous other fixes, please see the complete changelog for details

Okay. I will take a try.

Should I reset the factory default after firmware upgrade ?

Since My ip subnet is different than the factory 192.168.1.X
Mine is 192.168.103.X

For each factory reset, I have to plug my PC to router directly to access the router setting page.

I would for sure preform a full factory reset this is always a good idea when there is a driver upgrade.

could i restore the settings (backup current settings ) after a factory reset ?

I had the same issue on 378.55. Testing on 378.56 now to see if the issue persists.

Not recommended manually reconfigure is the best way to go.

Common issue on that model, i know at least 5 cases like this (not including my RT-AC87U RMA), and talking with ASUS close people theres some legions of cases, RMA is the way.

1 day in. No issues so far! But my 5ghz issue occured only about 1 week+ into leaving the router turned on.

From that post,
the found out of the 5G turn off issue is caused by high temp. of the 5G chip ?
