I can get my 2925 to connect to a wifi hotspot from my phone. Handy for the short periods when the Kelly gang are buggering about in the cabinet and you want to keep the whole house online with the least amount of fuss.

he does not have a wifi model so hence the usb wifi dongle option. Have done this as a temp solution with an AP connected to WAN2 on an AX router (it not supporting WIFI WAN is a right PITA)
