R7800 5ghz disappearing for a short time
R7800 randomly drops the 5ghz band and restore it back. "Select wifi network" window appears on my iPad 4 (ios 9.3.5), but when I choose "cancel" button it immediately reconnect to wifi network and ...
Hi m0a0k0s,
If that is the case, this means the router is working fine and it has something to do the devices that does not stay connected to 5Ghz. You might want to update the iOS version or contact Apple.
Hi m0a0k0s,
Try changing channels of the 5Ghz network. If still the same, reset the router.
Hi m0a0k0s,
We’d greatly appreciate hearing your feedback letting us know if you need further assistance.
I use this router only on weekends, so it takes some time to reply.
I've changed several chanels on 5ghz and have reset router several times but the problem still exists.
I can see it only if I use iPad a lot, that's not often happens.
Also my iPhone switches from 5ghz to 2.4ghz network after some time, maybe the source of problem is the same.
I have some devices compatible only with 2.4ghz, so can't turn off 2.4ghz.My WiFi settings:
Also iPad is registered only on 5ghz network, so it never switches to 2.4ghz.
iPhone is registered on both networks and it switches to 2.4ghz after some time (several hours) while it's lying near the router.Why haven't you enabled SSID broadcast on the 5ghz network?
I've just discovered next thing in router log:
[WLAN access rejected: incorrect security] from MAC address ..., Friday, February 24, 2017 15:07:36
[WLAN access rejected: incorrect security] from MAC address ..., Friday, February 24, 2017 15:07:33
[WLAN access rejected: incorrect security] from MAC address ..., Friday, February 24, 2017 15:07:12
[WLAN access rejected: incorrect security] from MAC address ..., Friday, February 24, 2017 15:07:09
It happened just in time when my iPad lost network again and it's the iPad MAC address.
I'm sure I didn't have those records in log before I turned on SSID broadcasting.I never change connection setting on iPad since I configured it with new router. iPad uses static IP address.
Moreover there's no way in IOS to explicitly change security options on already registered network, except unregister the network completly.Also I have "Turned on Access control" with "Allow all new devices to connect" checked.
