I had DD-WRT on a Linksys E1200 v2 router acting as a wireless adapter (for my desktop connected by ethernet), but its admin console became inaccessible. This was basically okay until I wanted it to connect to a different access point.
Since I was going to hard reset, I figured it might be time for a new firmware. But wow, DD-WRT hasn’t been updated in a while, is there some new hotness? OpenWRT doesn’t fit in the Linksys E1200 memory, so that’s not an option. Is there a fresh version of Tomato? Turns out, yes. FreshTomato.
Install. I followed https://easylinuxtipsproject.blogspot.com/p/tomato.html#ID3 pretty closely.
K26RT-Nversion of FreshTomato supports Linksys E1200 v2.

Don't resetafter finishing. We’ll hard reset to wipe settings.
Change local IP to avoid conflicts. Before we get access to the rest of the local network, we should make sure that the router uses a different subnet than others.

LAN -> IP Addresson a unique subnet. I used
192.168.5.1(with a subnet mask of
255.255.255.0) since nothing else on the network starts with
LAN -> IP Rangeon the same unique subnet. I used
192.168.5.50even though I only really need 1 address.

Configure Wireless Client mode. I followed https://learntomato.flashrouters.com/setup-wireless-client-bridge-tomato-router/ pretty closely.

TODO: Enable IPv6?
I did have IPv6 working with DD-WRT configured as a
Client Bridge (when it became inaccessible…).
That method involved setting the primary access point’s IP (v4, nothing v6) as a default gateway, and I don’t think the client router was running its own DHCP server.
So far, I have tried the settings described at https://home.wieringafamily.com/projects/ipv6-home/, even though the instructions don’t pertain to
Wireless Client mode:

IPv6 Service Typeas
DHCPv6 with Prefix Delegation.
