I bought a Lenovo K8 Note from India. I’ve moved to the US after some days and for almost a year, had been using the LTE compatible sims of the US without any trouble. Recently I’ve moved over to North Carolina and I had to change my carrier for that. Unfortunately, the new sim isn’t working on my phone. I tried contacting the customer service of the carrier company but they couldn’t help me. What made me frustrated is that such a giant company like Lenovo doesn’t have good customer support for their smartphones. The service centers  mentioned in the Lenovo Help App aren’t helpful. DOES ANYBODY KNOW HOW CAN I MAKE MY PHONE 4G LTE COMPATIBLE AGAIN?

Yoga 930 wifi dropping

I updated my system this morning and it did download an update to my wifi card.  It download RealTek WLAN Driver -10(64) V.2024.0.2.101.  


Now in the system logs it says, "

WLAN Extensibility Module has stopped.

Module Path: C:Windowssystem32Rtlihvs.dll"


Can I uninstall this driver to see if that would fix the issue?  If I can how would I go out doing that inside the device manager or no?


Also if I can uninstall it wont Windows 10 just reinstall it once I restart the computer?

Permanently Disable Broadcom Netxtreme on S20 running Win7

The onboard Broadcom NIC on my trusty old S20 running Win7 x64 died. I’ve replaced it with a PCI card that works fine.


The problem is that I’d like to disable/uninstall the Broadcom permanently. I disable it in the Device Manager, but every time I start my machine, Win7 reinstalls it.:smileyfrustrated:


Of course I’ve looked through Google, but I haven’t found anything that works.


Does anyone have a tip?


Thank you very much.
