Was rather shocked to find BT hubs don't allow you to change DNS servers anymore and force you to use their own ones, so I can't properly setup adguard.
What routers are people using now that are reliable and will let me control my own network configuration
I love my Microtik hEX S. It takes a minute to get used to the menus, but I really like how everything is laid out and managing using winbox. For 70 bucks it has a hell of a lot of features.
Before that I used a Ubiquiti Edgerouter X which I liked pretty well but I was not a fan of the web interface, it felt very dated; I also had issues with certain firmware updates that made the device pretty unstable. Eventually it kind of just died so I replaced it with this. I think I paid $50 for the ER-X, definitely recommend spending a little more for the hEX S.
One thing the hEX S can not do (at least that I have found) that the ER-X can that I care about is running a MDNS repeater. I have a couple subnets including one for IoT devices so this is necessary, as a slightly jank solution I ended up spinning up an Ubuntu server VM with separate NICs on the subnets I wanted to repeat between and running this binary to do the deed: https://github.com/geekman/mdns-repeater - if anyone knows of a better solution plz let me know.
Can confirm, I bit the bullet for a CR2004 last year and it took me a couple of weeks at least to set it up the way I wanted. Powerful, but steep with a capital S.
