by George·Comments Off on Windows 10, VPN, and WiFi Refresh Errors
I’m currently working on a project where I set up a Raspberry Pi to host a VPN server so that I can let my extended family view some private pictures. I previously had a PritUNL server running on Digital Ocean with a remote mLab MongoDB server, but it didn’t seem to work too well, with connections getting dropped and some serious compatibility issues. PritUNL does, however, have a very nice interface and supposedly better resource usage than OpenVPN Access Server, the limited-to-two-concurrent-users OpenVPN solution I was using before.
My current setup had a PritUNL client (running unknown in the background) and a SecurePoint client on Windows 10, with OpenVPN on my RPi set up through PiVPN. The SecurePoint client was very easy to use, and it worked when I ran it. After testing that it worked, I hibernated my PC and went to work. And that’s when things went wonky.
When I opened up my PC, I saw three WiFi networks, the SSIDs that are from my house. There’s no way those things would be available at work. No other network was available. I knew it had to be something to do with my VPN software, so I uninstalled those and rebooted.
The problem persisted. I looked online, and it showed me that Windows 10 used to have a bug where old, unsupported VPNs (Cisco) would cause some internet connection issues. So I ran the fix for that (using cmd.exe in admin mode):
netsh -d – resets all network configurations and settings, but MS recommends it only as a last resort
Basically, netsh -d worked, but it also erased all my WiFi profiles. I played around with netsh some more, and I learned you can export current profiles using this command: netsh wlan export profile folder=c:\WifiProfiles\, which sends the profiles to C:\WifiProfiles. It’s not very intuitive, or maybe because I only had one profile, but it would seem that netsh wlan export profile name="George's iPhone" folder=c:\WifiProfiles\ should have worked, but it sends me this error: Profile "George's iPhone" is not found on any interface.
Once you backup your profiles like this, you can probably use netsh wlan add profile filename="ProfileName.xml" interface="Wireless Network Connection" user=current to import profiles that have been erased. I didn’t try it because I didn’t have any profiles backed up.
Then I downloaded OpenVPN and didn’t know how to get it to connect, which actually requires you to put the ovpn profile into the C:\Program Files\OpenVPN\config folder, and then right clicking the system tray GUI to get the Connect option to appear. Without the ovpn profile, the Connect option doesn’t pop up.
Anyway, that’s three things learned today: netsh wlab show wlanreport, netsh -d, and OpenVPN config folder. And although PiVPN doesn’t support bridging, I can access all the network drives and printers that I need to.
by George·Comments Off on Windows 10 and a Black Screen after Login
I own an Acer W500, a tablet PC made a few years ago. It runs pretty well and I decided to upgrade it to Windows 10 just a few days ago. However, after upgrading, it ran into an issue where a black screen would appear after login, with a cursor.
What causes this issue? One might be drivers, and one might be Windows file explorer enhancements, such as OldNew Explorer. Another might be issues with monitor management, or that the system is doing a disk check.
What can be done? First get into Safe Mode. Press CTRL+ALT+DEL to get into a place where the system can be restarted, then press SHIFT+Power icon, then press Restart. This will bring up the troubleshooting menu.
For those that can get into safe mode, use this to uninstall any explorer enhancements or to update drivers.
For those with the check disk problem, it’s probably good to wait about an hour to see if the black screen will go away on its own.
For me, I was unable to get into safe mode since the safe mode boot screen would not recognize my USB keyboard. Anyway, I had already backed up all my data, so I used the troubleshooting menu to reset my PC (reinstall Windows).
Now, it works, although it is a little slower than on Windows 8, but the entire Windows system only takes up 10GB, vs the 15 with Windows 8 and 7.
by George·Comments Off on Windows 10 and the EETI Touchscreen Device (Acer W500)
As an owner of an Acer W500 touchscreen tablet PC, I was eager to upgrade to Windows 10. The upgrade seemed to run fine, although I had to restore the system using the Windows 10 system restore tool due to an error or conflict with the Explorer UI.
Everything seemed to work fine until yesterday, when the touchscreen stopped working. I had to plug in an external mouse in order to click things, and I used the On Screen Keyboard from Ease of Use settings to type things in very slowly.
What was the cause? I learned on HP forums that the newest version of the EETI Galax touchscreen device did not function properly. A poster suggested opening the Device Manager, finding the touchscreen device under Mice and Other Pointing Devices, then rolling back the driver. I did, and it worked.
Until the next day. After I restarted the system, I had an unknown device and zero touch capability.
I tried installing the official Acer touchscreen drivers, but as there is only a version for Windows 7, it didn’t work. I tried downloading the latest EETI PCAP touchscreen driver (Projected Capacitive), which installed, but didn’t seem to fix anything.
So I restarted again, and the “unknown device” reverted back to the old (newest), nonworking update. Another post on the HP forums said to use the EETI PCAP driverpatch. Thankfully, it worked, and I uninstalled the EETI Galax driver package using Revo Uninstaller.
For those using the HP TouchSmart or the Acer W500, this seems to work… for now.
