Hi,
I've installed version 44863 on a tplink 1043ND v2.1. the install went without issues.
My problems/questions are:
1. I have an old Asus tablet (android 4.x) that will not connect to the wifi. I get an "Authentication Problem". I got the same message even after I turned off wireless security. (it worked fine on the original firmware) [I've enabled the log, but there was nothing about the wireless in it)
2. I've configured a wireguard tunnel. it seems to work fine but it does not use the DNS configured in the peer tunnel, but it uses the static DNS from the WAN setup.
Another small thing is that whenever I change anything and click Apply Settings, the tunnel stops to function and I have no internet until I either disable the tunnel or reboot the router.
The wifi is fine, every other device connects and works okay. only problem is this specific tablet, that worked with this router (original firmware) and still works with my other router.
same with the wireguard, installed and works fine, the only issue is that it seems to ignore the DNS in the tunnel peer setting.
I've searched and read and counldn't find the solution

The problem is the tablet, not DD-WRT. You may have to manipulate some settings, but I'm pretty sure it's not going to connect. You have to ensure that you're using WPA2 wireless security, AES - NOT AES+TKIP. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Android 4x is very old in terms of wifi technology support...
Try using straight mixed mode instead of limiting it to NG-Mixed... you might have a b only radio in that old tablet.
Make sure you are only using WPA2-AES 128 for security
Make sure WMM is turned on.
It might be the tablet doesn't support WPA2 and only legacy WPA... I'm not the android guru about what wifi security was supported at what version of android...
do that homework and see what the device can support; but it's 6+yr old hardware for sure... My guess it it should have G mode for 2.4ghz and 802.11N for 5ghz, but likely no 5g support yet...5ghz was not common on phones until after kitkat...too cheap to invest in the new expensive standard... _________________ FORUM RULES
like I've said, I've tried to disable all wireless security and the tablet still won't connect ("authentication problem").
I have tried wpa2/aes, which is how my router was defined before. no go.
same tablet worked before with this router and is working still with a different tplink router.
the tablet supports WPA2 and n-only, as this is how it is connected to my other router.
i'll try changing the network mode

no special setting for DNS? what does the "Peer Tunnel DNS" entry in the Tunnels page for?
I don't want my traffic to use a public DNS when I'm connected to the VPN

For making the peer QR or config file (if you set up WG as server)
But like I said read the WG client setup guide, paragraph about DNS
If I understood correctly from the guide, I should set the static DNS to the VNS's DNS. (it is not a private IP range, but maybe it is restricted to when you are connected to the VPN network ?)
doing that, the wireguard tunnel won't start at all. until I switched it back to 1.1.1.1
but now the DNS leak tests shows cloudflare DNS... :/
