Lenovo y50, Unstable wifi, Potential faulty hardwar Realtek RTL8723BE
Hi,
I am having some issues with my wifi on my personal laptop, and I would need if possible some advice
- Base OS : Windows 10
- hardware wifi : Realtek RTL8723BE Wireless LAN 802.11n
- Driver 2023.30.0301.2016 (Latest version was installed before reinstalling my base os)
- Motherboard : wmic baseboard get product,Manufacturer,version,serialnumber gives me LENOVO y50-70 does not make a lot of senses for me, but otherwise I just get the serial number and version
Problem Description
My wifi is very unstable, I can connect to the router, sometime it works properly, some time I don t internet connection. The error i get can be DNS resolution or web site not reachable.
I get the same problem with different routers
Interesting and make investigation very difficult for me is that I almost don t get any events
the only events related that I get sometime is 3 WLAN Auto Config (Errors)
EventID 40003
Description WLAN Autoconfig detected limit connectivity, performing Reset/Recover,adapter
code1 0xC 0x4
code2 0xDEADDEED oxEEC (really did not like this one as i believed I was being pwned, but looks like it is the drivers that return that)
Code 8 0x0 0x0
Usually it happens once when I reboot, and I get informational WLAN auto config entry saying that it went well, so I don t think it is the problem.
From there, it changes between working and not working
The only other event I get are for example warning because DNS failed, but it makes sense to me.
What I have done:
- Investigate events
- reinstall drivers
- flush DNS. route tables
- search on the internet for similar issue
- Reinstall base os
I am just done reinstalling, and I have the same problem.
What I think
I have a computer science background but windows is not the OS I work with, and don't know much about hardware. Lack of event does not really help me to investigate. I think that my wifi card is dying (It is a good computer, but it is not the first time i get hardware failure ...), but before buying a new one i would need your advice:
- Do you think of other investigation that would reveal a software problem.
- Based on what I said, do you think I am right to think about hardware failure, for me it would explain why it is not just not working, but it is unstable. Also for what i have seen, this wifi card is shit....
- Do you have any advice, that is the more important as I am not sure if a wifi card can be changed easily, if any wifi card can be used, if you have any advice for a good one.
Thank you very much for your answer, if you need any other information i will provide them
Have a good day
