Intermittent WiFi unavailable with 6250

[MFaga2]

I have a 6250 WiMax/WiFi card which has been working fine for several years. Over the past month, however, it has begun to intermittently have problems. The WiMax works fine, but the "WiFi on" option in the menu sometimes appears grayed out and I cannot access WiFi. This is becoming a huge problem. I have tried reseating the physical card with no effect. Is there some way I can diagnose whether the hardware is faulty? I am happy to buy a new card, but will be extremely annoyed if I buy a new card and the problem persists. Is there anything I can do?

Hello, on this case the recommendation will be to update the drivers for your wifi adapter and try again, if the issue persist I suggest you to contact the system manufacturer to get further assistance since this could be an integration or a hardware issue.

You can find the latest drivers at the following link:

I hope this help you to resolve the issue.
