Ubuntu 18.04 LTS usb wifi dongle freeze

**neset94** · May 7th, 2019

Whenever I connect to WiFi using my usb wifi dongle (TP-Link TL-WN725N) the computer freezes and I have to force reboot. If I share my iPhone internet connecting with WiFi and connect my computer to it with the usb wifi it works almost perfect, but the system sometimes still completely freezes and I have to force reboot.

Just started using Linux yesterday so I'm still learning all the terminal stuff but here is some info:

~$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 002: ID 04ca:002f Lite-On Technology Corp.
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 045e:07fd Microsoft Corp. Nano Transceiver 1.1
Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

If I need to give more info please let me know and please let me know how to get that info because like I said this is my 2nd day using linux. Coming from windows.

to make it clear:
1. When usb wifi dongle is connected to pc and network is turned OFF pc works fine but of course no internet.

2. when usb wifi dongle is connected to pc and I try to connect to home wifi computer freezes.

3. when usb wifi dongle is connected to pc and I try to connect to iPhone internet sharing it connects and internet works on pc.
