[AR750S] Can't connect to router interface

Technical Support for Routers
1

I recently purchased an AR750S-Ext and it has been working well thus far. However, today when I arrived at a motel I have been to before, I could neither connect to the router web interface nor the internet at first. I was able to ping the gateway IP.

I already had the Wi-Fi network saved and saw both 2.4GHz and 5GHz LED lights on. After powercycling it, the motel’s walled garden page opened and I successfully logged in. I was able to access the internet, but still was not able to connect to the web interface.
I tried both ethernet and Wi-Fi. When I attempt to connect to a local device in the Android app, it just gives the the unhelpful message, “Wi-Fi change. Please check.”

I currently have the openwrt-ar750s-AdGuardHome snapshot installed and previously had no issues. I have Mullvad VPN setup and AdGuard is currenlty off. I’ve only installed a few packages:

openssh-sftp-server
luci-theme-material
wget
file
nano
luci-app-wireguard

I have the hardware switch setup to toggle the Wireguard VPN. I tried switching it off and on again.

I’m probably going to reset the router in the morning and restore my backup of the openwrt-ar750s-3.104 firmware. I just wanted to report the issue.

Seems this is strange.

Can you pls check if your phone/notebook still get IP like 192.168.8.x from the router?

3

Yes, my phone and laptop have normal local IP addresses from the router.

I just reset it using the button and restored my backup I made right after setting it up with the 3.104 firmware.

Now it won’t upgrade packages:

I guess I’ll have to reset and start over.

EDIT: I just used the Revert Firmware option and set it up again. I’m still getting the same error attempting to upgrade the same packages as above. I’m at a loss now.

EDIT 2: I manually flashed the 3.104 firmware using the upgrade option with no change.

Pls do not upgrade packages like that.

Seems openvpn 2.5 breaks something.

6

You’re saying I shouldn’t use opkg? What’s the recommended way of upgrading then?

7

You should not update packages that has been installed on the router which may cause various issues.

You can install new packages, which generally will not cause trouble.

You’d better upgrade firmware only.

8

What? That’s rather insecure, isn’t it?

Sounds like I’m better off with installing vanilla OpenWRT, then.

9

Insecurity is relative. If you blindly update all your packages on Ubuntu for example, configuration files might get replaced with a default you don’t want, leaving you open to unexpected security issues.

Specifically with the AR750s, if you update to the latest OpenWRT you might encounter random crashes, that is why GL has not updated to the latest OpenWRT yet, until those issues have been found.

As Alfie wrote, even for advanced users, its better to stick with the latest GL testing version.

10

Point taken. I use the unstable branch (basically Arch stable) on Manjaro Linux on my computers, so I’m used to a rolling release model. I guess I’ll have to slow down a bit in this case if I want a stable router.

11

you sound like you know what you are doing, go for vanilla/official openwrt you won’t regret it :rocket:

12

it’s the same with vanilla openwrt. it says opkg upgrade is highly discouraged.

Yeah look at the link @reflector posted.

The entire top part of the page is a 18 line block of warning text basically telling you not to use opkg update.
