AR750S repeating 5GHz issue

tauceti · 2018-09-18T11:23:25.543Z

@nopro404: I don’t want the same SSID for 2,4 and 5 GHzbecause then I cannot check if there are really 2 wlans broadcasted…
and as written the 5GHz is not broadcastet or available…

tauceti · 2018-09-18T18:38:41.399Z

well if the AR750S cannot repeat a 5GHz into another 5Ghz wlan the whole router doesn’t make sense…does it work for you??? @kyson-lok can you please advise?

@tauceti Could you ssh to the router, then issue cat /etc/config/wireless, show the output.

I can’t reproduce this situation.

Understood your issue. For 5G there was a bug to work as repeater when there are a lot of DFS channels around. When this happen you will not connect to the Internet.

This was fixed and you download the testing firmware to have a try.

@alzhao I already updated to latest testing firmware.!

Anything new? It is the main usecase I bought the device for. I also tried many settings in LuCI and also resetted the whole device but the 5GHz wlan is only available and visible when I deactivate the repeated 5GHz wlan in LuCI. Do I have a faulty unit?

@tauceti We are on vacation now. We try to investigate this issue asap.

are you still on vacation or could you please continue investigating? @kyson-lok
Thanks!

I see you had changed the wireless configuration file. What did you modify? We can’t reproduce this issue.

Could you reproduce it, and then show me the system log?

tauceti · 2018-10-01T04:44:22.818Z

Ok I will reset the whole device and start from scratch and then send you the logs.

tauceti · 2018-10-01T21:40:22.303Z

it is strange. with the latest testing firmware (29.09) I cannot see my 5ghz WLAN when scanning for networks in AR750s router. It is only shown as DFS. Is the channel the issue? my 5Ghz Wlan uses 108 channel.

tauceti · 2018-10-01T22:14:51.534Z

I retried and found out that the problem must be somehow that I have 2 WLANs (2,4 and 5 GHZ) with the same SSID. When I use only a 5GHZ WLAN with a unique SSID it seem to work

Try checking your timezone / location. I saw the DFS channels when I accidentally had it set for Asia rather than the United States…

kyson-lok · 2018-10-08T08:49:31.829Z

Do you mean the router itself SSID?

tauceti · 2018-10-08T10:29:44.015Z

Hi,

I re-examined: have 2 routers (not GLI fabric) which each send both a2,4 and 5 GHz
WiFi all with the same SSID. I get the above problem with the third Router (which is my AR750) when repeating the 5GHz WiFi but only if both other routers are operating. If I disable one non GLI router it works. Strange.

kyson-lok · 2018-10-10T07:08:56.904Z

Thanks for your feedback, we will investigate this issue.

kyson-lok · 2018-11-01T09:27:52.504Z

@tauceti Could you please upgrade the latest testing firmware? Here is the link to download. Please untick “keep settings” when upgrading, and don’t using luci instead of our webui to connect your upstream AP. Please let me know if this version fixed the issue.

tauceti · 2018-11-02T14:39:02.981Z

Hi Kyson-lok,
thanks for the reply. It seems to work now. Perhaps it is because of the autochannel feature which is now enabled?

kyson-lok · 2018-11-05T02:00:52.381Z

Not sure why, because we can’t reproduce this issue. However, we had fixed some bugs for 5GHz repeater, such as inconsistent bandwidth, channel issue and so on.

I meet with the same problem. I take gl-ar750s-3.006-1104.tar firmware and start with clean configuration: the problem remains. A750S prefectly uses 2.4GHz Wi-Fi as WAN, but fails to use 5GHz WiFi as WAN. I have saved config and logs. Here is my /etc/wireless:
