Cannot connect to wifi after upgrade to Windows 10

I had always expected a few glitches after doing an in-place upgrade from Win7 to Win10 (v21H1) on my Samsung RF511 laptop (which is a few years old but in theory capable of handling Win10). After sluggish boot-up and touchpad issues (raised in separate posts), this one is about wifi connection.

The problem is simple. No wifi. Ethernet (which uses a Realtek adapter) works fine, so my internet connection as such is good. When trying to make a wireless connection, the laptop running Win 10 "sees" the wifi link. The router is a Netgear, again not the latest model. It has WPA password-key protection. But running Win10 now, the laptop "can't connect".

The laptop has a Broadcom 802.11n network adapter. With Win7 before the upgrade, the wifi connection worked fine. When dual-booted into Linux Mint on the same machine, the wifi connection still works fine. This suggests that both the Netgear router and the Broadcom adapter hardware are operating properly. The only thing that has changed is the upgrade to Win 10.

I have run the Win10 wifi troubleshooter. I've done the standard steps it asks (switch the router off and on again...). It says there is a problem.... but offers no suggestions for how to solve it.

I have looked at the network adapter properties/drivers. The driver is v.5.100.82.95 which appears to date from 2011. It is said to be working properly. Windows Updates offers no more recent version, and trying 'update driver' in Device Manager brings the message that the installed driver is the right or best one.

The Broadcom support website is hopeless, but I did find, download and install a more recent driver - v.7.5.340.0 dated 2015. No solution - the wifi still will not connect.

A laptop that can only connect via ethernet hard-wiring is not very useful. So what else can I try in order to get a wifi connection?

 

Wifi very slow on laptop, but ok on other devices - Windows 10

Hi Annu

I've had the same problem as Panayiotis1984. Upgraded to Windows 10 on my Lenovo from windows 8.1 - now the wifi is painfully slow. The wifi still works fine on my other devices (smartphone etc).

I tried the steps that you suggested but they did not bring an improvement.

Any other suggestions?

Wifi Very Slow

Hi,

The following are some reasons that may cause of the slow WiFi connection.

• Corrupted or incompatible drivers.
• Missing updates.
• Network connection settings.
• Hardware or software problems.
• Inappropriate distance from the router or obstruction.
• Interference with other devices.

To isolate the concern, have you checked if the issue persists with other devices? For now, we suggest that you follow the troubleshooting steps provided in this
