SSID question

[Tray51]

I need to delete old SSID and change to new on. Problem is I don’t know what the old number is as I received this from a friend and they don’t know either.

For general help for new router or printer please refer to this article in our printer database.

Please provide the exact model name of the printer for better assistance as I may be able to find videos to show how to connect or fix the problem. A printer can be a PRO or a PLUS or have the letter 'e' after the number and that can make a big difference. Some printers with the same number ID could be a LaserJet, Deskjet, or Officejet.

If your printer model ends in the letter 'e' then click the spoiler for special needs.

HP+ printers are designated by a lowercase "e" at the end of their model number (e.g., 8135e rather than 8135). These models are enabled for HP's smart printing ecosystem, which requires a permanent internet connection, an HP account, and the exclusive use of Original HP ink for the lifetime of the printer.

Click Spoiler if you have a new router, have not reset the printer, and nothing else changed.

New ISP, same old printers, PCs and smartphones: Log into the modem or router and change the SSID (names) of each band so the names are different. Create a numeric password identical for each band to simplify login. If you must use alphanumeric characters then do not use any from this set: ilL1oO0D8B5S as they are easily mixed up depending on the font used. Be sure to run the application (if any) that finds the best channel for each band. Your ISP should be able to do all of this for you if you need help.

If you configure the new router with:

• The same SSID (network name) as the old router
• The same Wi-Fi password
• The same security type (typically WPA2-Personal or WPA2/WPA3 mixed mode)

Your printer may reconnect automatically. However, your PC may have an old IP address, but you can always tell the PC to find the printer, and it will obtain the new IP address.

If you have multiple repeaters or Wi-Fi boosters or 2.4ghz cameras / appliances, there are additional settings required.
