Asus RT-N66U, build 44715. It's connected to a standard ISP provided router.

I set it up as a repeater according to the wiki - https://wiki.dd-wrt.com/wiki/index.php/Wlan_Repeater

The 5G band is acting as a repeater and the 2.4G band is an Access Point (I have tried with a VAP and the same thing happens). I configured the OpenVPN Client and everything works fine when the VPN is on. Any traffic connected to the Asus router runs through the VPN.

However, when i disable the VPN, the internet connection goes with it. There is no kill switch configured and i cant figure out the problem.

Report back when you have upgraded and the problem persists

The forum guidelines will tell you how and where Smile

If the problem persists we need a more accurate description e.g. if you disable the VPN do you have internet?

And 47256 dropped, so you should likely flash and test this release.

https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2021/08-25-2021-r47256/broadcom_K3X/dd-wrt.v24-47256_NEWD-2_K3.x-big-RT-N66U.trx

Also, repeater modes may be a little tricky; they may or may not work. You may have better luck with Client or Client Bridge.

FWIW I upgraded my R6200v2 to 47256 configured as 2.4 GHz WLAN Repeater (using same wiki guide) with 5 GHz AP connected to my R7800 connected in bridge mode to ISP modem..
For fun I configured OVPN client to PIA. No killswitch.

All working fine VPN enabled and disabled connected wired or wirelessly. No PBR configured.

Possibility exists you may need to reboot your devices
after changing VPN status.

The upgraded software fixed it thanks. I thought i had the latest version but must have been looking in the wrong place.


The lack of speed under OpenVPN from the puny CPU caused me to go out and buy a shiny new router that now outstrips my ISP connection speed, but that's another story Smile


FWIW:
ISP - 25Mbps
Asus under OpenVPN - 6Mbps
WRT3200 under OpenVPN - 32Mbps

Looks like you are getting the full bandwidth on VPN now. But that increase is normal, cause their modems use bits for the rates. 250000000 bps = 31.25 Mbps. There's 8 bits in a byte. Smile
