  1. Can only connect one way on networking


    Okay, an interesting situation here. Up until recently I could connect via my ethernet networking fine, between 2 PCs, both ways. Both my PCs recently upgraded to 1903, approx 1 week apart. I have zero idea if it is coincidence, but now I can only access one of the PCs, not the other way around. So for instance I have a Ryzen and Intel PC, I can now connect to the Ryzen fine, but the Ryzen can not connect to my Intel. Yet last week everything was fine. Whether the update is relevant or not I am unsure, as it worked okay when one was updated. I can ping both PCs IP address fine from each other.

    I have checked all IP4 / IP6 settings, all are set to automatic, etc. I have been through most guides online. I have also rebooted my router and waited 10 seconds, I have also reset both PCs multiple times. I have disabled firewalls on both PCs (they both use ESET). The Intel PC is Windows 10 Pro and the Ryzen is Windows 10 Home. Both via 1gbps wired ethernet. Ryzen PC is Realtek NIC and Intel PC is Intel NIC. I have tried ipconfig/ flushdns and ipconfig /renewdns and ipconfig/ registerdns to no help.

    Now here is the interesting bit, if I use the ipconfig /release command on the Ryzen PC then I can suddenly access the Intel PC fine, as though it suddenly unlocks, BUT, it disconnects me from the internet and up comes the "no connection" world grid icon in the tasktray (which used to be the monitor and exclamation mark on older windows versions) and says "Unidentified Network". If I ask windows to rectify the problem using the network troubleshooter, it then gets me back to the normal network (upon fixing it says "Ethernet doesn't have a valid IP configuration - Fixed *green tick*"), but it then stops me accessing the Intel PC on the network again. I have no idea what this means. Oh and just to mess with my mind more, when I use the /release command on the Ryzen PC I can now no longer access the Ryzen PC from the Intel PC (like I normally can) until I rectify the issue on the Ryzen with the network troubleshooter (which then as mentioned stops me accessing the Intel PC again, arggghhhh).

    Not sure if this is related but my Epson wireless printer beeped at me at 4am last night saying "IP already in use" on the small LCD printer screen, not sure why. Also yesterday afternoon I was having internet speed issues so I tried another router modem I had in the shed as a spare and also tried the 2nd NIC (atheros) on my Intel PC motherboard. However I changed back to my existing router and the Intel NIC within minutes when I noticed the speed wasn't helped, so was purely a temporary change which shouldn't have altered anything as everything went back to how it was.

    Any ideas ? Thanks.

    :)

  2. Losing network connection

    Hello Dear, if you have a laptop or a PC with a wireless network adapter, you can see a list of available wireless networks and then connect to one of those networks. The wireless networks will only appear if your PC has a wireless network adapter installed, the adapter is turned on, and the wireless access point is in range.

    1. Click Start, click Control Panel, click Network and Internet Connections, and then click Network Connections.

    2. In the left pane, under Network Tasks, click View available wireless networks.
    In case, If you don't see the network you want to connect to, click Refresh network list. If you see the network but the signal is weak, move the PC closer to the wireless router.

    3. Click the network you want to connect to, and then click Connect.

    4. If you're connecting to a secure network, type the security key, and then click OK.

    I Hope you solve out your query soon.
