A couple of days back I switched on my ols computer again and.... it died. Along with it a few other components in my network died: one swith completely broke down and another lost a few ports. Those parts have already been replaced.
The last issue that I am aware of at this point are repated to my printer, an Epson PW700X all in one. It has lost its capability to print over (wired) LAN at the same time, but its wifi is still operational. My wife still manages to get prints off the thing using her laptoip and my andoid phone does so too,
The problem is that both my laptop and my sons don't.
My sons lapton runs Win 8.1 x64. My wifes laptop and mine run Win 7 x64. All three run the same Panda Internet security software, incl. firewall.
There has been no issue at all while the printer was operating on wired LAN. It is set to manual IP configuration for WiFi, the same settings at it had in its wired days: 192.168.33.222 / 255.255.255.0, gateway 192.168.33.1 (=Fritz!box 7390).
I've done some experimenting on my laptop: removed all Epson software, downloaded the latest (for x64) and installed it. No firewall warnings/blocks, the test page printed perfectly and the inserted SD card could easily be read. A 1st printjob from MS Office caused no problem either.
The next day however, the printer "could no be reached" and the mapping to the SD card could not be reestablished. I have not been able to fix the issue.
