One of the worst things about those routers other than having generally poor coverage despite looking like a Crown of Thorns was that if you actually took advantage of the more advanced features like VLANs, port forwarding, static routes, FTP and all that stuff and set it up… It inevitably seemed that there was a 99% chance that a firmware update would not allow you to restore a backup of the router config on the updated device!

That happened a couple times, spent days getting everything set up only to find out the firmware update refused to load a config made with an older version. F that. Never used those routers again.
