I am facing some weird issues with created hotspot on my laptop.
My details:-
Code: Select all
Laptop:- Fujitsu Lifebook A555
Linux Mint:- 18.3 Sylvia (Cinamon X64)
Wifi & network adapter
02:00.0 Network controller: Intel Corporation Wireless 7265 (rev 61)
Subsystem: Intel Corporation Wireless-N 7265
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)
Subsystem: Fujitsu Limited. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
Kernel driver in use: r8169
Kernel modules: r8169
So I decided to start FRESH.
From GUI: Went to network connections & removed the network Hotspot. This removed old config file for the hotspot. Then added a new connection and set connection name, SSID:-Mint-Spot, passkey etc. Here is screenshot of same

I could hotspot config File created like below
makrand@mint-fuji1 /etc/NetworkManager/system-connections $ ls
IDC-MGMT Mint-Spot
Checked the contents of Mint-Spot Files.
[connection]
id=Mint-Spot
uuid=11718dd2-d8da-4215-a16b-96aba1ae78a8

interface-name=wlp2s0

Now my hotspot is displayed with name Mint-Spot and I can connect internetid to it and access interent on android.
So I decided to turn off the hostspot. After I turned it on immediately, the hostspot aquired network name like 'mint-fuji1' on its own and config file for hotspot as been modified to below. Note:- it didn't changed the PSK key. Only SSID was changed.
Now I can see mint-fuji1 as available wi-fi network from my android. But if I connect to it, I can't access the internet. I tried pinging 8.8.8.8 (google public DNS) from my android and below is result. 10+ erros.[connection]

After this, I rebooted the laptop and now I could connect to Hotspot from android and can access the internet
So here are few problems
1) I am not sure why its resetting the SSID name to mint-fuji1 when I turn hotspot on & off (or reboot laptop). Seems in spite of the set name of SSID, its taking mint-fuji1 as default. Strange!
2) Why I can't access the internet from android connected to hotspot most of times?
3) Why rebooting laptop fixes the issue?
Things tried so far:-
1) I've updated network manager to the latest version from update center. But no luck.
2) This problem is appering only after reinstalled (no upgrade....just format and reisntall) OS to 18.3. with 18.1/2 hotspot used to work fine.
I am really confused now. Any clues??
