ASUS X205TA WiFi on Ubuntu Budgie 19.04

I just installed Ubuntu Budgie on this little laptop and everything works flawlessly EXCEPT wifi. It was an issue in Windows 10 too, which is what prompted me to try Linux on this thing. I followed this answer but the nvram thingy in efivars isn’t there (there isnt a single nvram thing in there) and copying the command gives in fact cp: cannot stat '/sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113': No such file or directory as a result. How do I get the txt file I need to make this work? Do I have an alternative to this to make the internal card work? with this distro? I don’t want to use an external one because the ports on this laptop are a bit flimsy and for some reason the slightest little bump makes it disconnect and reconnect. Thanks. EDIT: I should mention that I don’t care about bluetooth not working

Why kubuntu 18.04 LTS freezes/hangs when it’s trying to connect to wifi using usb wifi adapter?

I have two newly-assembled machines at my office, I have installed Kubuntu 18.04 LTS whenever I try to connect to wifi using Tplink TL-WN725N OS freezes. I haved used lshw and wifi adapter driver is already present. It’s been one week and I can not find a solution to this problem. Please help!

Can’t connect to a specific Wi-Fi network because of “Reason 2”

This is a new network that I haven’t connected to before, it uses WPA2.

The laptop can connect to my phone’s hotspot and my phone can connect to the problematic Wi-Fi network. As I live with other people I’m not allowed to touch the router and its settings so all I can work with is my laptop.

The problem is I get deauthenticated right after I get authenticated. This is the output of dmesg:

[  583.623274] wlp2s0: authenticate with xx:xx:xx:xx:xx:xx [  583.674097] wlp2s0: send auth to xx:xx:xx:xx:xx:xx (try 1/3) [  583.682346] wlp2s0: authenticated [  583.682581] wlp2s0: associating with AP with corrupt beacon [  583.688023] wlp2s0: associate with xx:xx:xx:xx:xx:xx (try 1/3) [  583.696076] wlp2s0: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0x431 status=0 aid=6) [  583.698537] wlp2s0: associated [  587.736455] wlp2s0: deauthenticated from xx:xx:xx:xx:xx:xx (Reason: 2=PREV_AUTH_NOT_VALID)

I have checked that the password is correct multiple times and I have selected Personal WPA2 in the security settings of the network.

What can be the problem?

WIFI Connection breaks down when connecting to HDMI

I have switched from Windows to Xubuntu a couple of weeks ago. Most things work so far. However, if I connect my laptop to HDMI the download rate sinks to zero and my Internet connection vanishes. The second I disconnect the HDMI cable the connection re-establishes and everything works as usual.

I have an Acer Travelmate 5742, an Intel(R) Core(TM) i5 CPU M 560, my wireless interface is:

description: Wireless interface product: BCM43225 802.11b/g/n vendor: Broadcom Inc. and subsidiaries

I have a proprietary driver for my WIFI. Furthermore, I had to make some adjustments to be able to use brightness control:

Section "Device"         Identifier  "card0"         Driver      "intel"         Option      "Backlight"  "intel_backlight"         Option      "TearFree"   "true"         BusID       "PCI:0:2:0" EndSection

Can anything of my adjustments cause these problems?? I switched to VGA (which works perfectly) but I do not intend to stay this way…

I appreciate any help! Thank you!

Has Wi-Fi hacking gotten almost impossible?

I have read about Wi-Fi password cracking for a while and used different tools my self, such as:

  • Airodump for monitoring
  • Aicrack for getting key from cap files for WEP/WPA/WPA2
  • Reaver for WPS
  • Bully for WPS
  • Reaver and bully with PixieWPS for WPS

I have tried the tools on WEP, WPA and WPA2, where only WEP is able to get cracked. The weak point of routers was WPS, but reaver and bully seems outdated and I have not gotten them to work on a single router yet. WPA2 cannot be cracked as far as I have understood, and the only way to actually get a password from WPA/WPA2 is by having a word list, which in itself is an extremely bad solution. There is an incredibly low chance of a password being in a word list, and if we talk outside the USA, they are non existant. Since WPS cracking seems to be secured, WPA/WP2 not being able to be cracked without word lists and WPA3 on the way, would that mean that currently Wi-Fi with WPA/WPA2 protection is most likely impossible to hack?
