I have a wired network with two Western Digital PR4100 (NAS), and several Windows 10 workstation, plus one Windows 7. I have a Zyxel modem/router and TPLink switch. No wifi.
About a month ago I was hit with a power surge that knocked out power for about 10 seconds. No, I don't have a UPS protecting my two NASs. Ever since that power surge, my Window 7 Home PC is unable to connect to one of the two NAS with any regularity. Prior to the surge, everything worked perfectly. The other NAS connection is ok about 80% of the time but it will sometimes drop as well. The Windows 10 PCs connect with both NAS ok.
After the power surge:
I replaced both NAS under RMA, so the enclosures are brand new (thinking the network card within each might have been damaged).
I replaced the NIC in my Win7 PC.
I replaced the switch.
I replaced the modem/router.
After all that, I can still only connect to one of the two NAS with regularity.
If I unplug the LAN cable from the back of the NAS I'm having trouble with, and then plug it back in, I have access to that NAS from my Win7 machine for several minutes only to have it drop again. I've tried turning off my firewall and anti virus. Didn't help. I've turned off/on network file sharing which results in a brief moment of connectivity.
Interestingly, I can always PING from my Win7 to NAS, so I know the connection is alive at a very low level.
Anyone have any other ideas that I may have missed, short of replacing this Win7 pc (which I'll probably need to do early next year anyway).
Thanks in advance.
