I want to get a WiFi dongle with the 802.11AC or later standard that is compatible with Linux 4.13 (with Ubuntu 17.10) for a desktop PC (Streacom FC8 mini unit), 64 bit, intel core i3-2130).
Context: I have an Ethernet connection but a flatmate pulled it out in the past because he suspected that it was slowing down the connection for everyone else (which may be true). I went and bought a Vivid Wireless router and used that for a couple of months, but it costs $90 per month for an unlimited plan. A few days ago I reconnected the Ethernet to the old router and have used it fine, however an hour or so ago I couldn't use the internet and it would prompt me to log in to the router ISP gateway. So I suspect that the flatmate denied access for the Ethernet connection as he has access to the gateway, although he denies changing anything. While resetting the router may cause the username and password of the gateway to change to the default, there is no button to be felt after prodding around in the reset pinhole, so I'm unable to reset it and can't login in to the gateway. I've posted on a Telstra Forum saying the same thing.
Initially the dongle I had worked with Windows but it wouldn't and was not supported for Linux. So I bought another dongle that was Linux compatible but it didn't work, so I got a refund. Here are the results of trying to get it to work. I read this which says that AC dongles may be difficult to setup.
A useful source of information is https://wikidevi.com/wiki/Main_Page.
The TP-LINK Archer T4U is a dual band 802.11ac USB adapter.
It uses the Realtek RTL8812AU chipset which many have had good results getting 802.11ac in the 5GHz range working with Linux. Good 802.11ac USB dongles have been slow to come about and often require some setup for the drivers.
Here is a link to Realtek RTL8812AU chipset and Linux. https://github.com/abperiasamy/rtl8812AU_8821AU_linux
If you are looking for a easy setup than going with a known working wireless-N dongle would be better.
Then from the https://github.com/abperiasamy/rtl8812AU_8821AU_linux readme:
Known Supported Devices:
- COMFAST 1200Mbps USB Wireless Adapter(Model: CF-912AC)
Interestingly, the seller of the first dongle said that the chipset is RTL8812AU! So I'll try that with the instructions in the abperiasamy repo.
That didn't work.
I bought an AC600 WiFi dongle, which works plug and play, which is able to connect to my router sometimes, and only sometimes.
I went back to using Ethernet connected to the router, but the housemate wanted to unplug it on Feb 1 2018, so I did.
So I used a WiFi extender (Netgear WN3000RP) that is already in the house (but is meant to be used for others; although nobody has complained. I plugged an Ethernet cable into that and connected the other end to my computer.) The internet works fine with this setup. I bought another extender, getting an AC1200 one, in order to get more reliable and faster speeds, although the speed with using up to 300 Mbps works pretty well.
