I have the printer in my living room and despite having a descent wireless router the printer shows 2/3 bars signal. My other equipment all have full reception at the same location so my guess is the wireless receiver in the printer is a cheap one.
Sometimes it just drops the connection in the middle of a print wasting paper and ink. Very frustrating. I emailed Epson support about this a while ago but so far I have not received a reply. Has anyone else had this problem?
here is an example, sometimes it can stop after 95% complete!!!
The issue could be caused by the physical location of the antenna inside the printer. Turning the printer for better orientation can sometimes solve this type of problem.
Also, a 2.4 GHz cordless phone near the printer or between the printer and the router could be causing interference.
