Laptop disconnects from Wifi at random intervals


My laptop is randomly disconnecting from my new router. Sometimes it's every few minutes, sometimes it can be an hour or two in between disconnections. This only seems to effect wireless devices and I notice it most often on my laptop. The router is a Fritz!Box 7490 and is connected to 2degrees Internet. The message in the WLAN event log is :

[table][tr][td]Wireless LAN device deregistered itself (5 GHz). MAC address: 64:BC:0C:6A:79:62[/td] [/tr] [/table]

The weird thing is that if I disconnect from wifi and reconnect it re-establishes the connection near instantly. Sometimes it just shows as connected to wifi but not to the internet.

I have tried factory resetting the router (As suggested by 2degrees Internet) and I've tried setting my laptop DNS settings to 8.8.8.8 and 8.8.4.4. I have also tried to change the wifi channels in case of interference.

Any suggestions or advice is welcome and I'm happy to provide extra info on request. Thank you for your attention.

 

WiFi disconnection /download speed reaches 0 upon lid close


Hey Everyone!

I have a HP pavilion ab221tx laptop. The wifi chipset inside it is a realtek rtl8723BE. I am noticing that download speeds immediately reach zero upon lid close & may be the laptop's wifi also disconnects. By the time I open the lid and the display turns on,the wifi would have got connected.

I googled a lot but was unable to figure out if it's an OS issue/os build issue/setting issue.

I have tried things like
*reintalling the driver from oem site & also updating it
*disabling power saving options of the wifi adapter".
*tweaking advanced settings in power plans (ensured wireless adapter performance is set to maximum in all power plans)


I am facing this issue since the last three days. I remember installing certain apps like PC Remote(Beta) & WIN-Remote Control, which enable you to make your android smartphone's touchscreen act like a laptop's touchpad. While doing this , I came across an article where they suggested to enable "wake on magic packet" in the advanced tab of LAN adapter properties. I just went there to check if it was enabled or not but I found it to be enabled (ideal setting as suggested). Thereafter I had changed none of the settings.

I have since uninstalled all those "pc control softwares/ reinstalled those wifi and lan adapters/re-enabled maximum performance of the network adapter in power plans/disabled sleep "do nothing" on lid close & re-unchecked allow the computer to turn off this device to save power but still face this wifi disconnection issue upon lid close. I really do not understand what went wrong!

Is it likely that these softwares would have caused the issue? How can I fix it?

 

WiFi disconnects, must close and reopen laptop to reconnect


Just to add some info, when I try to open a new tab in Chrome it often says "not responding" then the wifi will shut off, forcing me to close and reopen my laptop. Really desperate for help!
