An Epson TX810FW is connected to the rest of a network using WiFi, and its been working well for a while.
But suddenly, it stops printing.
I take a look, thinking its just lost its IP address, or it cannot find a DHCP server.
Sure enough, its configured to use DHCP, and often, if the DHCP server gives it a new IP address, then suddenly, nobody can print to it.
So I decide to work around this by using a fixed IP address.
But it doesn’t work, as I’m now having problems getting the printer to recognise the WiFi router… The printer has a ping diagnostic, but that fails.
It could be something peculiar with the WiFi encryption (although its been a while since I’ve seen devices that cannot cope with standard encryption protocols.
Just to be sure, I change the WiFi router to have no encryption… but the printer still cannot connect via WiFi.
OK, at this stage there are 2 possible options:
- The Wifi Circuitry in the printer has failed.
- The whole network circuitry in the printer has failed.
So I connect the printer using an ethernet cable to the router, and after some configuration, the printer works just like before (but this time with wires).
So once again, I’ve seen WiFi circuitry fail
