Windows 10 recognised network but no internet connection(ethernet)

Knarfster · 15 Jan 2017

Hello,

Yesterday the ethernet connection to my wifi range extender dropped randomly. I've had this problem specifically with a LAN connection before, but have always been able to sort it out by resetting the connection between the router and the extender, which are connected through power socket. Now the wifi connection randomly drops and is unreliable which is to be expected as it was never that strong to begin with, as well as the ethernet connection showing no forms of life at the moment. From troubleshooting the only error that's found is "default gateway is not available" and in the network center both connections simply state "no internet".

I've tried changing from DHCP to an assigned IP-address for both connections using multiple DNS-servers, for example copying the result of the ipconfig/all command (results attached) as well as using Google's DNS servers, but this only seems to add another problem to the troubleshooting process while solving nothing.

I've tried downloading and installing new drivers for both network adapters and made sure that neither are handicapped by power eficiency settings. I've also tried using older versions of the drivers still present on my computer.

This has led me to think that the problem lies with the range extender but resetting the router or the extender hasn't worked out for me. The extender in question is a Devolo dLAN 500 duo powerline adapter. The other desktop in the household seems to have no problem connecting through the powerline to the router and has a reliable and fast connection.

Any help would be greatly appreciated. I have tried different things trying to solve this issue on myself and have reverted everything to the settings on which I had a connection until yesterday, but there's the possibility I've forgotten something.

Welcome to the TenForums @Knarfster

Lots of problems with connectivity. It looks like from your screen grabs you are connected by cable and wireless.

Just so everyone understands, can you connect through a wire to your power adapter and get Internet connectivity and it just spotty with wifi?

Here is a link to a tool to visualize your wifi. Please scan with your AV before opening. It will show you channel and strength. If you have lots of overlap and signal is weak where you are trying to connect then you should look at switching channels on your powerline. Assuming you are using 2.4Ghz bandwidth. Please confirm.

inSSIDer 3.1.2.1 Download - TechSpot

If you don't want to use tool run this command. It will list networks in your area that card sees, including yours. You can copy info and paste into next post. Watch any privacy info.

There is a windows Network trouble shooter, not sure if you have used. Type troubleshooting into Cortana, click on Troubleshooting at top of list. When window opens click view all in upper left. When you open Network trouble shooter, click on advance and run as admin, then click next.

In network settings, under Network there is also a network reset.

If that does not correct things here is a list of commands to execute. Stuff in brackets after command tells you what it does. You can research on Google.

From command prompt(admin)

ipconfig /flushdns (Clear the dns cache)
nbtstat -RR (release and refesh NetBIOS names)
netsh int ip reset (reset ip settings)
netsh winsock reset (Reset Winsock Catalog)

I like the idea of an older driver. I usually recommend heading to your machine makers site and getting the driver there. Asus, HP, Lenovo, etc. If they have a Win 10 driver great, if not Win 8.1. Install it. Note driver version. If this works and then it stops working look at driver versions again. Windows is helping by updating drivers. If this is the case you will tell it to stop helping.

Thanks for the response, I can't really access the computer tonight as I don't seem to have any USBs or cables around, I'll post the results of those commands tomorrow. For clarification my pc is connecting to the wifi hotspot both by ethernet cable, which was usually the fastest/most reliable, and wireless. Now neither seem to work, but the problem seems to specifically arise for my pc only. I have tried using troubleshooting but that lead me to the error of "default gateway is not available".

I've also tried accessing the Realtek website but seem to not be able to for god knows why. I can look up third party sites for the drivers but I read in another post that the chipset for the adapters can be important in knowing which driver to download. As seen in the logs I posted earlier I'll need to look for GBE PCI-e drivers specifically, is that correct?

I would suggest that while you try to isolate this issue, either connect wireless or wired.

In some circles for security reasons when you connect both, one drops out. Where I worked we enforced that, now it happens on many systems automatically. Imagine being connected to a corporate lan, accepted and passed through security, then connecting to a rogue wireless network. Your machine becomes a bridge which is a security no, no.

Yes you need the right driver and it should state in the device manager what the adapter is. Then head to the manufacturer of your PC or Motherboard.

I would also suggest, with extreme caution, that you disable your AV & firewall for some testing. One thread had this as a solution. You need to test against trusted sites and even they may present risk with malware advertising. I'm not recommending this as a normal mode of operation.

Can I ask, what are you using for AV and what type of PC, Motherboard are you using?

I've downloaded inSSIDer and it shows that the hotspot signal is being transmitted on 2.4 GHz, I'm not sure if the hotspot even has the possibility of transmitting at 5Ghz. Attached is a screenshot for the hotspot the network the hotspot creates. I disabled the ethernet adapter before I checked.

I've also run the network commands you told me to, which led to a message saying "access denied" but still told me the reset was complete. After rebooting the pc it didn't seem to have done anything for me.

I'm using Norton as AV and I've tried changing the network setttings etc. while I had it disabled already. Motherboard is always a bit of a hazardous guess to me as my PC was prebuilt and I can't seem to find any sellers online that mention the motherboard. I didn't really pay attention to that when buying my PC. The only info I can find is that it's a Medion MS-7848 H87 AHCI.

I've just found a driver on the Medion site that specifically mentions the Realtek 8168 for windows 10. I'm going to try to install it after completely uninstalling my current driver.

Thanks for update. Well running commands performed the resets so we know it not the ip stack for example. I might try moving channel to channel to channel 4, its a little clearer.

Interesting that signal is at 54. How far away are you. I assumed since you connect with cable you are in same room. I would have expect in the 30's.

Note driver versions as you go. Also try without AV cautiously.

We all do things differently. Can I ask why you are cable and wireless connected?

The hotspot is located like 4 meters/13 feet away from the computer. I keep the installation files for every driver I download branched in one folder. I'm connecting through both wireless and ethernet because ethernet has been faster and more reliable in the past. Sometimes for downloading I connect through both as there seems to be less downtime.

Everytime I try to install a realtek driver it shows me the options only to delete or change the current driver even though I've just deleted my current one. Does this mean I didn't fully remove the driver (which I tried through device manager) or is this just some oddity in the installation process?

I'm considering to put the router on the other side of a thick wall so that I might be able to connect wirelessly to the router directly as is possible downstairs at the moment. That would still leave me with a faulty hotspot though and probably a weaker connection.

I honestly have no clue how to change channels in inSSIDer as the learning tab doesn't really teach me anything. Do I have to configure that through hotspot settings? I don't recall ever configuring them even when we set them up.

Well I guess the signal makes sense if you are 4 meters away and you have a thick wall in between. Concrete and masonary is not the best median, nor is wood wall filled with duct work and electrics.

Myself I would just connect wired if I could as that should be fast. Wired ports, today, come as either 100 Mpbs of 1000 Mbps. To get 1000Mbps both posts have to rated at that speed and the cable needs to be a quality cable. A Cat5E cable will support a 1000Mbps although I believe it is rated at 100Mbps. You can get over 100Mbps on wireless but you need at a minimum an "N" class radio, good reception and a source that produce. If you look at inSSider screen shot you sent it says the device can produce 150Mpbs.

To move forward I would suggest you enter the device manager, find your wired adapter and uninstall it, when asked, remove the driver software. Then shut off your wireless radio, please. (Either a function key or physical switch on laptop). Then install your wired driver. Reboot and connect cable.

You don't change channels in inSSider, you either enter your router or extender, and change the channels on the device.

I figured I'd give you an update. I've contacted the company of the hotspot and they notified me of an known error that's solvable with a workaround so that got my wireless connection working. The problem with my ethernet connection seems to have been the box for our television threw some problems into the mix for the modem. After that acted up we reset it and now I can actually get internet through my ethernet cable as well.

Thanks for bearing with me and apologies for the slow responses.
