I'm having severe issues w/ package-loss and a generally bad connection w/in a WiFi-network at my uni. I'm usually encountering a package loss of ~50% and aborting connections which makes working w/ SaaS impossible.  I'm using Ubuntu 13.04 and my network-adapter is an Atheros AR9462.  Applying the nohwcrypt=1-option doesn't change anything.  Also very noticable: The connection works as intended in other networks; the problematic network uses WPA2 w/ MSCHAPv2.

Note - I know nothing about Linux, just switched over from Windows. Also not an accomplished coder.  Installed Ubuntu 16.04 on a Dell laptop; it worked.  Installed it on an HP laptop (model 17 -x061nr) and the wi-fi will not work. In Network Settings, the option to turn Wireless on is present, but when I click it on it immediately switches back off again. I have no Ethernet ports available. I can download something on the Dell laptop and transfer it via flash drive, but that's it.  The HP's network controller is a RTL8723BE PCIe wireless network adapter, from Realtek. Prior to installing Ubuntu on this laptop, it was running Windows 10; the wi-fi worked there. The wireless isn't entirely kaput - the first time I switched it 'on,' the name of my wi-fi network appeared for half a second before the wireless switched off.  I've powercycled the laptop, reinstalled Ubuntu, and disabled, then re-enabled Networking. I looked in Software &amp; Updates; it had one notification that the device is using an alternative driver (Processor microcode firmware for Intel CPUs from intel-microcode (open source)). I've tried enabling the wireless with and without using that device.  I've looked around the forums for similar issues, but haven't found anything quite like this.  Advice? Any further info required?  rfkill list all: 0: hci0: Bluetooth     Soft blocked: no     Hard blocked: no 1: phy0: Wireless LAN     Soft blocked: no     Hard blocked: no 2: acer-wireless: Wireless LAN     Soft blocked: yes     Hard blocked: no   Update: Wi-fi is now enabled.

On my 74mb connection I only get about 37 mb/sec; hardwired I get about 67 mb/sec and on my Windows PC I used to get over 70mb/sec with WiFi.  Why is it slower on Ubuntu?

I'm testing Ubuntu 18.04 with my current desktopand everything works correctly except for the Wi-Fi adapter. I'm using a TP-LINK TL-WN8200ND version 2.  As requested , my wireless-info output is at .  I've tested Mint 19, Kubuntu and KDE neon, with similar results.  Is there an official driver that works out of the box?

I recently updated my Lenovo Y50 computer to 16.04. Since the update, I have been unable to see or connect to any wireless networks. The output of running sudo lshw -C network is:     *-network UNCLAIMED          description: Network controller          product: BCM4352 802.11ac Wireless Network Adapter          vendor: Broadcom Corporation          physical id: 0          bus info: pci@0000:08:00.0          version: 03          width: 64 bits          clock: 33MHz          capabilities: pm msi pciexpress cap_list          configuration: latency=0          resources: memory:d1600000-d1607fff memory:d1400000-d15fffff   The fact that the wireless network controller is unclaimed leads me to believe that this is a driver related issue. I have checked and made sure that "Use proprietary driver" is checked in System Settings > Software &amp; Updates > Additional Drivers and I have run sudo apt-get install --reinstall bcmwl-kernel-source I have also restarted after every driver change to finish the changes.

I have purchased a TP-LINK TL-WN823N (EU) V2.0 device, which is a USB device that should work as a Network Interface Card, allowing me to connect my computer to wireless networks. Unfortunately, I am unable to find any wireless networks using this device using either wicd or network-manager (no networks appear in the list of networks supplied by either application).  A CD came with the device claiming "Linux support". The CD contained a URL to a corrupted archive file for downloading installation resources. I try to mask my immense frustration.

I have a HP 14-AN001NA laptop. It came with Windows 10 installed on which the Wi-Fi worked fine anywhere in the house.   However I removed Windows 10 and installed Ubuntu 16.04 instead and since I have had terrible Wi-Fi anywhere aside from about three foot away from the router. I don't know if it's relevant but my Wi-Fi is not called wlan0 but wlo1 for some reason (I didn't change it).  When running lspci -knn | grep Net -A3     I get the following output:  05:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723] DeviceName:   Subsystem: Hewlett-Packard Company RTL8723BE PCIe Wireless Network Adapter [103c:81c1] Kernel driver in use: rtl8723be Kernel modules: wl, rtl8723be

I have just installed Ubuntu 20.04 and I am facing a pretty big issue. My download speeds are really low compared to the Windows 10 that I have installed on dual-boot setup.   This is the speed I'm getting in Windows.    And this is what I'm getting in Ubuntu.   My network adapter is Lenovo RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller.   I have tried changing the DNS options but that doesn't help.  Device is a Lenovo Y700-15ISK Laptop.

I bought an ASUS USB-N53 wireless-N Dual-band USB wifi adapter. It does not install on my Ubuntu 11.10 system automatically. I cannot figure out a way to get it installed.  Any advice?

I've been trying to get Ubuntu to run on my HP 15-an000nd. It has been a huge pain all the way.  My last (big) remaining problem is Wi-Fi. The signal strength is very very weak.  lspci gives me the following concerning wireless:  02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device 522a (rev 01) 03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter 04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller (rev 0a)   I have tried the following:  sudo rmmod rtl8723be &amp;&amp; sudo modprobe rtl8723be   and it tried to install these drivers:    I also set this parameter in the config file :   options rtl8723be fwlps=0   but nothing helps I still barely get any signal.  Any help is greatly appreciated, Greetings.

I have a Lenovo Yoga 13 and I was running 14.04 on it and I've since upgraded to 16.04. I applied the fix descibed here () with 14.04 and it worked but no longer seems to with 16.04. I know that the way Realtek drivers work was reorganized in Linux kernel 4.4 () however I don't know enough about what was changed to know if that was the problem. Has anyone else experienced this issue or know how to fix it?
