Wanting to cut my losses, I decided to buy a cheap router. Found a Kasda 6512 for ~$22 bucks. It's a great router (we even have service in the backyard now).
If anyone else wants to take a look: the product is /B071HRYKJQ/ on amazon.
It is an Open-WRT router
8MB Flash - 64 MB RAM
I haven't used Gargoyle before, and this device isn't listed on the compatible devices page, so I thought I'd check to see if anyone else had attempted an install.
Any feedback or direction would be greatly appreciated!
