My home wifi network has two Google Wifi access points (APs). My desktop computer is running Ubuntu 17.10 and is literally a foot from one of the APs.  Unfortunately, instead of connecting to this close AP at 5GHz, it usually connects to the AP on the other side of the house at 2.4GHz, obviously creating a very slow and unreliable connection.  I have two questions:   Why would Ubuntu not automatically select the closer, stronger, faster AP? Assuming this isn't something that happens automatically, how can I force Ubuntu to choose the better AP?   N.B.   I found some related answers in the archives but they all seemed targeted to older versions of Ubuntu and Network Manager (pre-Gnome), and are no longer relevant. I'd prefer not to hardwire my computer because I have other equipment that needs to be hardwired and not enough ports.

It worked, the it dropped, then it worked, now it won't connect to wireless. Brand new Asus laptop that came with ubuntu is connected. The problem seems to be with Ubuntu. It keeps asking for authorization codes for my neighbors signals as well as my signal which the asus is connected to.

Context  I have purchased a new  laptop which has Windows 7 Home 64-bit which has this Wi-Fi Option: Intel ® Centrino ® Advanced-N 6230 (2x2 agn + Bluetooth)  And I have 4 Mbps Internet connection with a  Wireless router.  Problem  When I use internet on my laptop by wired LAN it works very good very fast. But when I use internet on Wi-fi it works very slow, and most of the time it doesn't work properly.  Any solution for this?

I have a laptop with an Atheros card and I woud like to use it as a wireless access point.   I need an AP with WPA/WPA2 encryption for testing purposes; I don't need any routing functionality or anything else (it's fine if it has that, but it's not a requirement).   A live CD would be good, I just want something that's easy to setup -- like I mentioned, it's not for real use. I tried it on Ubuntu but I guess by default Ubuntu is missing the special drivers required to act as an access point.

My Panda USB wi-fi adapter works just fine on 16.10, but when I try to connect to my wi-fi router in 17.04, GNOME network manager reports "Connection failed." I did some tinkering, and noticed that my MAC address for my wifi adapter, according to GNOME, is DIFFERENT every time I make it forget my wifi settings and try to reconnect. Any leads on a possible fix or work-around?   I'm running Ubuntu GNOME 17.04, kernel 4.10.0-19-generic, GNOME 3.24.0.

So I just started using linux/ubuntu today and I've been getting problems with my wifi, ive tried the solutions on this page:  When im really close to my router, its fine, i can see wifi signals, but when i go just a few steps back it disappears right away. Im using the latest version of ubuntu 17.10  Any suggestions would be nice! :)

I have recently bought  laptop, which comes with  Kaby Lake processor, I have installed Ubuntu GNOME 16.04.1 on it, and it is unable to detect WiFi adapter.   Upon running lspci -nnk | grep -A2, I'm getting following information about adapter.  028005:00.0 Network controller [0280]: Intel Corporation Device [8086:24fb] (rev 10)         DeviceName: Intel Dual BandWireless-AC 3168 802.11 ac 1x1 WiFi + BT 4.0 Combo Adapter         Subsystem: Intel Corporation Device [8086:2110]  But running rfkill list all, I see following output (WiFi missing there).  0: hci0: Bluetooth         Soft blocked: no         Hard blocked: no  And here's the output for dmesg | grep iwl.

Now, I don't know if this adapter is supported by 4.4 kernel that Ubuntu 16.04 ships with, or it requires manual fix, as my laptop doesn't have hardware switch to turn on/off WiFi. Also, this being a combo adapter for both WiFi and Bluetooth, I can use Bluetooth just fine. Ethernet works too.  After searching around Intel® Dual Band Wireless-AC 3168 I found  page which suggests that support for this Wireless Adapter was added starting Kernel v4.6, and since 16.04 has Kernel 4.4, I tried two things.  1) Upgrade Kernel  I manually installed 4.7.3 from , and booted into it but WiFi still remains undetected.  2) Loading firmware for this adapter version (3168).  I searched for .ucode files for this adapter and found it on . So I copied iwlwifi-3168-21.ucode and iwlwifi-3168-22.ucode files to /lib/firmware/ and rebooted, but still no luck.    Update  This seems to be a linux-firmware related bug, and I have filed the report on . However,  given by  seems to fix WiFi under Kernel 4.7.4, but it breaks Bluetooth which was working fine with Stock Kernel 4.4.0-38. I'm still looking for a proper fix which doesn't cause any regressions (I'm fine with upgrading to newer stable Kernel release).

Here in the UK, everytime you sign up to an ISP they will provide you with a router to connect at home. These are usually cheap netgear home routers (the one I'm using is a DGN-1000SP) with a basic GUI firmware. With 3 people in the flat, we usually have around 6 devices (3 PC's and 3 mobile devices) but sometimes up to 10 as more devices/guests come into play.  However, I've noticed that the network slows down massively when the number of devices get to 8 or so. Logging into my router's GUI I notice that the list of attached devices keep changing; sometimes there are as little as 3 devices connected and sometimes all 6 are shown.  Is this because the router cannot handle all the simultaneous requests (hardware fault) or because the internet connection is too slow? The connection is ADSL with 5Mbps down and 1Mbps up.  What are some ways I could fix this? Will establishing another access point with my spare router, wired to the original access point but broadcasting a different wireless channel and throwing traffic to this router help if the problem is to do with hardware?

I would like to extend a WiFi signal. I could buy a WiFi repeater, but a much cheaper solution would be using an older Android 4 device, which I own and don't use. The Android device is capable of creating a WiFi AP. So if I bought an external WiFi USB adapter for it, with a large antenna used as the receiver and the Android device itself as the AP, I could bridge the network.  The hardware should be possible. But how about the Android software? Will there be any issues, or any considerations I need to take note of?

Please note that this question is specific to Intel WiFi adapters.  My laptop is an HP ENVY with an Intel AX201 Wifi Adapter. I've dualbooted Ubuntu with Windows.  AX201 WiFi adapter is not supported by latest Ubuntu 18.04 version, because Ubuntu 18.04 comes with Linux Kernel 5.0, whereas support for AX201 comes built-in in Linux Kernel 5.2+. Canonical claims that Ubuntu 18.04 will get Linux Kernel 5.3 sometime next year. However, I wont be able to wait that long.  I tried downloading and installing Kernel 5.2.14, but I cant go beyond Grub: I get the error:     error: you need to load the kernel first.   Other option is to download the Intel Backport Driver, which I tried. That didn't seem to work either. As per the tutorials, I've restarted frequently, but that didnt work either.  Also I'm not quite sure if Intel IWLWIFI Backport driver supports AX201 in the first place.  WiFi works while I'm booted in Windows.  What should I do?  Thanks in advance!  UPDATE  I tried out @Pilot6's answer, and it worked. Thanks!  I have one last question: I've read that if you upgrade the Kernel beyond what Ubuntu 18.4 supports, its kinda unsafe (which I read as prone to system crashes).  I dont want system crashes because I have only one partition (root) for Ubuntu, and any crash would likely mean all my data is lost. One method forward would be to split my Ubuntu partition into root and home.  So if I want to access WiFi on my device safely without risking any crashes, what should I do?  My understanding of Ubuntu and Linux may be wrong as they are built on forum answers only. Please correct me if Im wrong anywhere.

I have two  ethernet adapters that give me near ideal internet access on my media computer (FIOS 25/25mpbs tests out at 8ms 25.4/24.7) and perhaps 100-140mbps to my router, printer, drive, etc.  I now want to add a few wifi points and instead of having the mess of a powerline adapter + a wifi router I think it will be neater to have an all in one solution.  Most of  are 200mbps, however.  I know that 500 is backwards compatible, but will a mixed solution slow everything down like it can for a mixed wireless g/n network?

I recently upgraded from ubuntu 13.10 to ubuntu 14.04. Wifi (with ralink rt3290 card) was not working in ubuntu 13.10, but after the following the guide here, , it worked fine. But in ubuntu 14.04, no matter how much I try it does not work. Can anyone please figure out what the problem is and how to solve it.

When I turn WiFi on, my 3G connection shuts down, which is fine in most cases. However, I need to connect to a LAN at work that is not connected to the internet and I'd prefer not to lose my data connection when I connect to the work intranet. How can I keep both connections active? Ideally, I could limit this desired behavior to this one SSID because I want it to continue to operate with the default behavior for all other WiFi connections.  If that can't be done, prefer a solution that is easy to toggle on and off. I'm using a Samsung Galaxy Nexus (Verizon Wireless) on CyanogenMod 9.
