Greetings to anyone who takes the trouble to read this post!

 

For a while now, I’ve been having an annoying situation with my Wi-Fi at home. I did some research, but I can’t find any useful tips on Internet, so I was wondering if anyone has any ideas for helping me.

 

It’s like that: We have three laptops at home, all running Windows 10, as well as a host of other devices (smartphones, tablets, Chromecast), which all connect, via the Wi-Fi, to the Internet. The phones, tablets and Chromecasts usually rarely have a problem connecting to the Internet but, often, if one laptop is switched off/has gone to sleep and is woken up, it will connect to the Wi-Fi but a yellow triangle will appear on the Network icon on the bottom right hand corner of the task bar, it will say “No Internet Connection” and the thing will not go on the Internet. This usually happens when one or both of the other laptops are connected to the Internet. The problem goes away by simply resetting (unplug and plug in again) the router, but then one of the other laptops might lose its Internet connection.

 

The thing is annoying; restarting the router when you want to get on the Internet interrupts the connection for all the other users and if you keep doing that it gets on everybody’s nerves. The only thing the provider suggested, when I managed to get through to them, was switching to a different “Channel” on the router, but I have done that several times and it has not really changed anything.

 

I would really be grateful for any tips that might work. Thanks in advance!

A place to start: Disable Fast Startup on all your Windows10 computers. This uses a hibernation file for supposedly faster startup but it can give problems.

 

https://www.windowscentral.com/how-disable-windows-10-fast-startup

 

Once disabled open an elevated command prompt. Windows key +  X  > Powershell as admin. Type the following commands

powercfg.exe -h off

Reboot. See if that helps. If not then on the Windows 10 computers you can do a Network Reset. 

  1. Select the Start  button, then select Settings  > Network & Internet  > Status > Network reset.
  2. On the Network reset screen, select Reset now > Yes to confirm.

Thanks! I followed your advice on all of the Laptops, but the problem persists. I am convinced the problem lies with the router, not the individual laptops. Any suggestions anyone? By the way, the router is a Netgear one.

On the Windows 10 computers that have a problem see if giving them a static IP outside of the router's DHCP server addresses helps.

At the moment, I have now idea how to do that :) I could google it, but if you could point me to a page explaining how to do it, I'd be much obliged. 

 

By the way, since the problem just reappeared on one laptop, I went and looked up  the Network properties of the connection on that laptop and noticed that the following columns were missing (when compared with another laptop which was on the Internet on the same Wi-Fi): Link Speed, DHCP enabled, DHCP servers, DHCP lease obtained, DHCP lease expires, Defautl gateway,  Network name, Network category.

 

Connectivity (IPv4/IPv6) showed "Connected to unknown network no traffic" i.e. it does not even recognise the name of the Wi-Fi Network. 

 

I should also mention that connection to the Internet is via a Netgear Wirelles Cable Voice Gateway CVG834G, to which my telephone line is also hooked-up. I'm in Europe and the service profider is sfr, formerly numericable, formerly coditel. I haven't been able to find much on the Internet on that particular device. Most importantly, I don't know if (and how) to update the firmware. 

 

Thanks again JohnC_21 for your interest and efforts and also thanks in advance to anyone else who might take an interest.

You're Welcome,

 

In your router settings you will see a range for your DHCP server. It can be in the range of 50 or so addresses. Outside of that range would be your address to create a static IP address.

 

This page provides the steps. 

 

https://portforward.com/networking/static-ip-windows-10.htm

 

For your DHCP address range see page 4-9 of the manual.

Edit: The above manual is cbvg not cvg but it should be close.
