Question Laptop WiFi not connecting to some specific hotspot

[halderarnab320]

Recently my laptop wifi is not connecting to some specific mobile(iPhone 6s) hotspot. My mobile hotspot is connecting to other laptops and mobile but when i try to connect from my laptop it's starts showing connection is taking longer than usual and then not connection...even it's not showing the password option. But my laptop is connecting to other wifi networks. Previously it was connecting to my iPhone but before few days it suddenly stops connecting.

System Specs:
Lenovo Z51-70
Win 8.1, 64bit

Wireless Driver:
Qualcomm Atheros QCA61x4 Wireless Network Adapter

This: "is not connecting to some specific mobile(iPhone 6s) hotspot".

Where, whose iPhone 6s hotspot are you trying to connect to - is it actually your iPhone 6s or someone else's?

The wording is somewhat contradictory: "specific mobile(iPhone 6s)" vs "was connecting to my iPhone".

Has the laptop wifi connected to that hot spot (either someone else's or yours) before?

If all other connection paths/hotspots, and devices are connecting then the desired hotspot device is likely blocking your laptop.

Double check the wireless configuration settings.

It's my iphone and yes the laptop was connected previously but now it's not...I've also cleared all saved wifi passwords from Manage Known Networks still it's not connecting.

My thought is that there was some update with respect to drivers and/or configuration.

Are you certain that only one network adapter (wired or wireless) is enabled on the laptop?

On your laptop use the Command Prompt to run "ipconfig /all" (without quotes) and post the results.

I am wondering about the IP address lease time: Seems to be limited to 12 hours.

Is it possible that your hotspot is using a WIFI channel that is being excluded by the laptop driver ? The 5Ghz band has lots of restrictions depending on geography.

Some hotspots limits the number of concurrent clients. How many are you using at a time? It might be a limitation of apple or the carrier in question.
