Hi everyone,
I have already found a solution to the problem I am about to discuss, I am just posting this in case it can help someone else. I am also wondering if there was a better way in case I missed it.
I have a Fedora 14 desktop, an F20 laptop, and 2 F21 laptops. All run wireless except for the desktop. All all 64-bit. I have a wired network connected Epson WF-2540 printer, using the Foundation driver epson-inkjet-printer-201211w-1.0.0-1lsb3.2.x86_64.rpm. I can print and scan from any machine without issues (well, thanks to some previous help from this forum).
The other day the printer said it was low on ink. It would still print (and look fine) so I kept using it. Maybe that was a bad idea? It eventually said it was out of ink (black) and refused to print anything else. Fine, I put it in Replace Cartridge mode and replaced it. I first tried my F14 desktop system since I use it for most everything. The printer icon still had the warning emblem on it and would not print anything. In system-config-printer I fiddled with the Enable button and eventually got it working again. Okay, fine, so I do the same with my F21 systems. They work as well.
Now comes the fun part: I do the same with my F20 laptop but it refuses to print anything, I then realize it can't even ping it. All of the other machines can ping (192.168.1.10) but not F20. F20 can ping everything else, and is on the Net. I close down and then reactivate the wireless interface, no good. I reboot, which I despise doing, no help (this really pissed me off). I look at the router, no help there. I do an strace on ping and get this at the bottom:
ioctl(1, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(1, TIOCGWINSZ, {ws_row=33, ws_col=118, ws_xpixel=0, ws_ypixel=0}) = 0 sendmsg(3, {msg_name(16)={sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("192.168.1.10")}, msg_iov(1)=[{"\10\0\34\377\16P\0\1\310 \351T\0\0\0\0Vg\6\0\0\0\0\0\20\21\22\23\24\25\26\27"..., 64}], msg_controllen=0, msg_flags=0}, 0) = 64 recvmsg(3, 0x7fff53ff24e0, 0) = -1 EAGAIN (Resource temporarily unavailable)
It will do this forever. I tried traceroute but it just returns the asterisks as expected.
So, what happened here? Is this a bug somewhere or did I miss something (again)? Or maybe this was corrected in F21. I was able to get around this problem by switching to the wired interface. It could now ping the printer, and then I could fiddle with the Enable setting (system-config-printer) to get it going again. After a few test pages I then switched back to wireless and that is now also working fine.
What did I miss? I did not do anything to the printer during this time.

WLAN & AP devices are?
I'm using the 5G side of my new Netgear R6200v2 router. I'm on Time Warner in Oahu using an Arris Surfboard SB6183 modem. No special configuration except for DHCP reservations. As I mentioned before it can print fine now, wirelessly, but I had to change to the wired interface to clear out the printer out-of-ink error condition. This sure sounds like a bug to me. However, this is on Fedora 20 and has possibly already been corrected. The Fedora 21s didn't have a problem, nor did Fedora 14 (but it's wired only).

That is AP/router, but what is Wi-Fi device on Fedora machine? lsusb/lspci

Sorry Poma, this is on a Lenovo ThinkPad T500. From lspci:
03:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection
It is using the iwlwifi driver.

Kernel and firmware versions are the same for 21/20, if updated, but not NM versions. You can try this, - make dir # mkdir /etc/systemd/system/NetworkManager.service.d - make conf file therein, to debug NM /etc/systemd/system/NetworkManager.service.d/debug.conf [Service] ExecStart= ExecStart=/usr/sbin/NetworkManager --no-daemon --debug - di dam di da # systemctl daemon-reload # systemctl restart NetworkManager - observe e.g. # journalctl -b -u NetworkManager -f
man 1 journalctl

Wow, it never occurred to me that this might be a NetworkManager foul up. I'll have this ready in case this happens again. Thanks!
