compatible alternative router?

@Sulamaye666 - browse to http://192.168.1.254 in a web browser.

From memory, I think you want 'Advanced Settings' > 'Wireless'

You're likely to be prompted for the admin password which can be found on the label affixed to the hub.

See here for further help. Note that ‘point browser’ means open your normal web browser and insert 192.168.1.254 in the address field. If you have a separate search box from the likes of Google then do not use that. https://community.plus.net/t5/My-Router/2-4ghz-and-or-5ghz-best-practice/m-p/1351966#M840
