Just a quick update — I ended up buying a Topton N100 and paired it with DDR5 RAM and a 500MB M.2 SSD. I installed OpenWRT by plugging the M.2 into my main PC and using BalenaEtcher to flash the image.
It took me about 20 minutes to configure the network, with some help from ChatGPT. It’s now been up and running for just over a week, and everything has been working great. No issues with gaming performance, and thanks to SQM, I’m getting more out of my connection.
