    Specs:
    iMac 27" i7 3.5GHz 24GB 3T Fusion HD - 10.10.2b MBP 13" 8GB, 240GB SSD - 10.10.2b iPad Air iOS 8.1.2
    Epson WF-2540 WIFI goes offline frequently
    I use an Epson WF-2540 with my Macs (actually an iMac w/ 10.6.8, a MBP with 10.9.2 and an iPad with iOS 7) and generally have success and quality printouts. Occasionally, the printer simply goes offline via WIFI (the WIFI light is off) and I get the message the printer is offline. The Epson FAQs and Support have been useless. I am told to clear the queue (which usually is empty), delete the printer setup in System Preferences and create a new one, reinitialize my router (the router is always fine for me and others on the network and is less than 3 feet from the printer), download and reinstall printer software and/or disable the firewall which I have never turned on. There is no problems with the power, no error message is displayed on the printer and my Macs are usually less that 5 feet from the router and printer. The Macs and iPad never loose connection. This has happened on 2 different brands of routers. If I turn off the printer, wait a little while and start it up, WIFI resumes and if something was left in the queue it automatically prints.

    Does anyone have anything else I could try to maintain the printer WIFI connection?

    Anyone else have problems with Epson hardware?

    Thanks in advance.

    You may have a defective or intermittent WiFi receiver (antenna or interface) in the Epson. I have an older Epson NX 420 which has never lost its WiFi connection. If all other WiFi devices are working normally within your network, that probably narrows it down to the printer itself. Not much you can really do except swap out the printer if you must have WiFi printing, or attach it to your Mac via USB.

    Something else: Look for any other devices that may be interfering with the WiFi signal to the printer. Cordless phones are infamous for interfering with WiFi signals.

    Arg! I didn't want to hear about a possible hardware issue. Maybe I should open up a ticket with Epson because the printer is still under warranty. Sigh!

    I thought about interferences but the router is literally 3 feet away (above on the wall) from the printer with nothing between them. My computers, which never loose WIFI, are further away and the printer is in between them and the router. I do have a TV on the other side of the room but I think that is far enough away to not be the problem. The cordless phone is on the other side of the house.

    Thanks for the response though.

    The cordless phone that's on the other side of the house probably does not provide enough RF to interfere so I think we can rule that out. (But let's keep it in mind, just in case.)

    Why don't you try changing channels on your router and try the Epson again to see how it receives from the new channel. You'll need to access the internal setup of the router to switch channels. For example... if your router is set to operate on channel 4, change it to channel 11. Changing channels on the router does not require setting up your Mac or other devices again as they will receive the signal automatically.

    Hmm! I currently have the router set to channel 11 because no one else in the neighborhood is using that channel. I was advised to use channels 1, 6 or 11 for best results. There are 3 on channel 1 and 2 on channel 6 in the neighborhood. Also, the router is actually an Arris Internet/phone modem so if I restart it I will kick 2 other Internet users and the phones for a while. Maybe I will set my alarm for 2 am and change it then, lol. I'll get back to you then. Thanks.

    Before I went to bed, I changed the router channel to 4, a channel which was not being used by anyone in the neighborhood. When I woke this morning, the printer was offline. I guess changing the channel didn't work. Next step is contacting Epson I guess.

    I'm wondering now if your model Epson has a "time out" feature built in to it? After so many minutes or units of time that it's not in use, it goes into "standby" mode and drops the WiFi signal? Do you think that's a possibility? Perhaps it's something that Epson would know.

    Yes, it does have a stand by/low powered mode and I have it set to 5 minutes. I don't think this is the issue because there are times it wakes fine and lets me print and there are other times that WIFI just drops.

    I filed a ticket with Epson today and have exchanged 2 emails with them. I told them everything I tried and they asked me to test a few things. The tests, including copying, scanning and printing a network analysis sheet were all successful meaning the printer itself is ok. It just drops WIFI occasionally. They just sent me another reply email and said I should call their tech support (of course no 800 number) and be near my computer and printer for further testing. I suppose that will be my next step on Monday. I'm just tired of dealing with the printer today.

    Thanks for your help.
