Good information here but …
1) My old router was disconnected and I don’t have a smart phone or wifi so i could not access the info supplied above. At a bare minimum the first four lines should be printed on that sheet given with the router.
2) The router I bought is a pcWRT CF-WR619AC and the info supplied on the sticker stuck to the bottom is wrong. Instead of http://192.168.10.1 it said http://192.168.0.1 like my old router and that number didn’t show anything in my browser. And my browser kept connecting to your website when I tried the pcwrt one.
The good news is that once I was able to check these forums I was quickly able to set up the router and eventually got my internet back.
