Windows 10: My laptop does not connect to the main router after setting up a wifi extender

I recently setup a TP-link Wi-Fi extender and since connecting to this on my laptop, I can now no longer connect to the main router. When I do connect it says there is no internet. This is only an issue on my laptop. On both my phone and tablet I can connect to the main router or the extender.I tried the steps suggested in this post https://answers.microsoft.com/en-us/windows/forum/all/i-cant-connect-to-my-wifi-but-i-can-connect-to-my/f6a054e1-7ec4-4c14-baa6-fa3fbfc97b3c but none of these steps worked, and actually briefly prevented my laptop from connecting to any network I have managed

Laptop won't connect to wifi/router - but will connect to wifi extender

Hi All.

The following has happened before, and then if fixed it's self, but started happening again 3-4 days ago and is still an issue.

I'm about 20-25 feet from the router, Normally it connects no problem. But since Monday afternoon my laptop won't connect to the router. It keeps saying "no internet, secured" when trying to connect.

As I said I can normally connect no problem.

I have a wifi extender and moved it closer to the office, I can connect to that.

I moved the laptop right beside the router (2 feet away) thinking maybe the distance is the issue but got the same problem.

I have a second laptop in the house and that connects to the wifi with no problems.

My laptop is a Thinkpad T470 - Core i5 / 16gig ram about 2 years old.

I've windows 10 pro.

As a lot of people are right now I'm working from home, so I need to try to resolve the issue as sometimes the extender doesn't work.

Thank you for your help.

 

connecting to my wifi extender

I cannot connect to my wifi extender (netgear) from my laptop. I have Windows 10 installed. I can connect with all other devices (cell phones).

I can connect to my modem/router but when trying to connect to the extender it says "internet not available". Any suggestions or has this nothing to do with Microsoft products?

 

Setting up a wifi repeater woes - all advice appreciated!

First off, setting up a wifi repeater is one of the most ridiculously painful experiences I have ever had with tech hardware.

The needs:

... to be able to repeat the wifi output of my Netgear DG834N v1 ADSL/router to the upper floor of my house through the Edimax wireless 300M Range Extender (EW-7416APn v2). To enable my iPad2, 3DS, laptop and anything else that roams to maintain connection and not suffer dropouts.

The questions:

1. How do I know that the roaming devices are using the repeated signal from the Edimax extender and not just grasping on to the weak signal from the DG834N downstairs?

2. Some advice on the net suggest the router and the extender share the same SSID, which seems logical. However some suggest that the router and extender need to be on different SSIDs - but if this were the case surely the devices would only connect to the same SSID and ignore the other SSID?

3. If they use different SSIDs will the devices automatically pick the strongest signal and switch to whichever SSID that is?

4. Some advice suggests using the same channel number for both router and extender, which seems logical. Some advice suggests using different channel numbers for the router and extender - if using the same channel number, does this create too much data and make the connection worse?

5. If using different channel numbers, will the roaming devices automatically choose the right channel number based on connection strength?

6. While using the program WirelessMon I can see both the router and extender and their respective signal strengths, channel numbers and SSIDs - but there is no way of telling if the repeater is in fact repeating the routers signal - is there any software that will show that?

7. Is there any one trusted source for setting up a wifi repeater?

8. Will my hair grow back?
