I'm a student who uses the laptop all the time and I have a problem with Wifi on the laptop. I don't really know what it is. I can describe the problem tho. For example, i closed my laptop last night, so it goes in suspend mode. I turn it on this morning and my wifi doesn't want to connect until I restart the laptop. It says that it's connecting and in Wifi settings the circle animation is spinning, turning Wifi off and on doesn't do anything. Here's what happens when I check to see my network info: sudo lshw -C network   *-network                         description: Wireless interface        product: Wireless 3160        vendor: Intel Corporation        physical id: 0        bus info: pci@0000:02:00.0        logical name: wlp2s0        version: 83        serial: 00:1e:64:e6:1c:93        width: 64 bits        clock: 33MHz        capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless        configuration: broadcast=yes driver=iwlwifi driverversion=5.4.0-52-generic firmware=17.3216344376.0 ip=192.168.0.14 latency=0 link=yes multicast=yes wireless=IEEE 802.11        resources: irq:129 memory:df100000-df101fff   *-network        description: Ethernet interface        product: RTL810xE PCI Express Fast Ethernet controller        vendor: Realtek Semiconductor Co., Ltd.        physical id: 0        bus info: pci@0000:03:00.0        logical name: enp3s0        version: 07        serial: f8:ca:b8:52:72:49        capacity: 100Mbit/s        width: 64 bits        clock: 33MHz        capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation        configuration: autonegotiation=on broadcast=yes driver=r8169 firmware=rtl8106e-1_0.0.1 06/29/12 latency=0 link=no multicast=yes port=MII        resources: irq:17 ioport:d000(size=256) memory:df000000-df000fff memory:d0000000-d0003fff  Also I have to mention that my Linux is doublebooted alongside Windows 10, but I don't think that makes any difference.

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.

The latest version of Ubuntu server (18.04) seems to demand network configuration and refuse to boot without it. I have no desire to connect the server in question to the internet for anything, and have installed previous versions of Ubuntu server without network no questions asked.  Is a network connection an absolute requirement for the latest version of Ubuntu server? Or is there something I'm missing?  The installation cannot proceed past the network configuration page unless an ethernet connection is active, by my current estimates. I have no ethernet network within range of the machine so can't test it on an internet-less network. I only have WiFi within immediate range (which does have internet access) but it won't recognise the device and it should be simpler to get the installation to happen without any updates than to go to the effort of finding the drivers to support the WiFi adapter.  Note that this is NOT a duplicate of  since the new installer seems to be the real problem here.

As my laptop does not have Ethernet port, to set up wireless, I need to install drivers offline.  My Ubuntu version is 14.04.3, and kernel version is 3.19.0-25-generic.

Now I am not sure what to try next. I am not Ubuntu expert, and would appreciate any help.  Thanks a lot in advance.

As Ubuntu 10.10 seems to neither detect my graphics card (Intel 82852/855GM) automatically nor use the corresponding Intel driver even after manually installing it, I am looking into manually configuring X (shouldn't I?). Where can I find the configuration files I need to edit?

So I did a fresh install of Ubuntu 20.04 on a computer with the new RTL8125B Realtek network card and I cannot get the network to work. I was very suprised since this is supposed to be the new feature of the 5.4 kernel (I have 5.4.0-26-generic installed). Does anyone have any idea on how to get it working?

since I bought my new laptop, with a wifi card Intel Wireless AC 9260, I cannot connect to any wireless network. When I choose the network to connect it tries to but at the end it displays a behavior like timeout connection. Any of you face a similar problem before? (Yes, I already did extensive searches looking for related problems but any solution worked).  Ps.: the wifi connection works fine in Windows.

I just installed the OS on my laptop and at first wifi didn't work. After connecting to ethernet and updating everything, the wifi is working. But it disconnects here and there and requires me to reload the service or reboot. The bluetooth on the card does not work at all. It is seen and hciconfig shows an address for it. However, I cannot find bluetooth devices with it. I have seen a lot of different posts with this card but most of them are older. Where can I go from here.

I need a PCI wireless adapter that works well with Ubuntu 12.04. I have looked around on the web but a lot of the information is out-of-date or confusing. Could someone point me to a wireless PCI adapter on Newegg or Amazon that they know works well with Ubuntu 12.04? I would really appreciate it.
