Check the user manual or contact your AP manufacturer for details. Channel This setting controls the channel your AP uses to communicate with client devices on your Wi-Fi network. Most APs should have this set to Auto by default. We don't recommend changing this setting unless you Have a good understanding of Wi-Fi channels Know how to determine the least congested channel in your environment Channel Width For optimal performance and compatibility, enable support for all channel widths. If configured for 40MHz only or 80MHz only, this setting prevents legacy devices that support only 20MHz from connecting to the AP.

Information on the not be duplicated There are many USB Wirless devices that have the RTL8811cu chipset, so the device may not look like the illustration. Also as many of these devices come with the driver on a mini cdrom and people don't have cdrom drives on their computer or laptop these days, you'll need to get it from the internet. Windows generic drivers for the Realtek RTL8811cu provided by Microsoft may cause stability issues or intermittently cause it to malfunction and causing instability in Windows. So, installing the drivers from Realtek are important if you are experiencing any issues like these. Basic Specs Multi-system compatibility, support Windows 10, 8, 7, XP, Vista, Mac.

I have recently bought a usb wifi adapter as my current network card does not get any 5Ghz signal. I used to run on windows 10 so no issue to install the driver. But I got fed up of win10 as quite slow on my laptop. So i have decided to install linux mint 19.3 with cinnamon desktop in dual boot 1 benanna88 Members 7 posts OFFLINE GenderMale LocationAustralia Local time0236 PM Posted 19 January 2019 - 0400 AM I have just set this computer up, and from the start have used this USB wireless adaptor to connect to the Internet. But it has always worked intermittently, usually working from startup and then disconnecting after a while. However sometimes it's not connected at startup, and sometimes I can unplug it and plug it back in to reconnect, while other times only a restart will get it working. And sometimes it will show available networks but not connect, and other times it won't even let me turn WiFi on. All very strange and inconsistent behaviour. And the adaptor worked at first without installing the driver from the CD it came with, but after the first time it stopped working I installed the driver, and now it doesn't seem to work without it. The other issue I am having which seems to be related is that shutting down or restarting the computer usually results in a blue screen with the Stop Code DRIVER_POWER_STATE_FAILURE. Doing some Googling led to me updating my graphics driver, which seemed to fix it the first time, but then it has continued to happen regularly. One thing that sometimes fixes it, although isn't alway necessary, is closing the Realtek application from the taskbar. And sometimes shutting down takes a long time, but I don't get the blue screen, just my monitors going to sleep shortly after clicking shut down, but then it restarts, presumably because it runs into some problem maybe the same thing. Again inconsistent behaviour. So, can anyone point me in the right direction for fixing this, or offer any suggestions?

Several things could be causing one problem or could be causing multiple problems. I tried to find more info on that computer and it should have WIFI capability without using the wireless adaptor. Is that possible? Something that might help in discovering the problems would be a report/ log from Speccy - System Information - Free Download Please post the Speccy report/ log or a link to the Speccy report. “Every atom in your body came from a star that exploded and the atoms in your left hand probably came from a different star than your right hand.

I don't think it would have WiFi without the adapter, but I guess the Speccy report below will confirm that. Let me know if that uncovers anything.

Should of looked further into the listings as they then state WIFI Adapter included. Perhaps others will have some suggestions for you. My only suggestion is to use cable instead of WIFI if at all possible. “Every atom in your body came from a star that exploded and the atoms in your left hand probably came from a different star than your right hand.

While WiFi dongles are pretty darned reliable, they, like all things, can and do have "lemons" or failures. Also make sure you match whatever you buy to have capabilities at least as good as your current router does so that you can maximize your throughput.

Getting another dongle might be the way to go, although if the current one is faulty I might see if it can be replaced. Thanks for your replies and help.

Eventually I will probably set something like that up. But in the meantime the eBay seller was kind enough to send me a different brand replacement, so I'll see how I go with that when I receive it.

Back to top 10 benanna88 benanna88 Topic Starter Members 7 posts OFFLINE GenderMale LocationAustralia Local time0236 PM Posted 23 January 2019 - 0517 AM Well the new adapter arrived today, but it had other problems. I uninstalled the software and driver for the original adapter before plugging in and installing the software for the new one, but from the start it couldn't 'see' my 5Ghz network, so I connected to the which was extremely slow. As in YouTube videos were choppy at 360p and wouldn't run. I tried restarting and giving it a chance, but then gave up and went back to the old one. The latest with that is that it still cuts out eventually, although seemingly not as quickly as it used to, and the computer restarts and shuts down normally most of the time.

It certainly sounds as though it is not. Just as an aside, when it comes to external hardware that requires or is likely better equipped to function with a driver other than what's already in Windows, I strongly suggest installing that driver software before ever plugging in the device for the first time. Most OEM instructions state that this should be the order as well.

The replacement adapter is an EDUP Dual Band WiFi USB Adapter and I double checked on the computer that it was dual band. It also showed the neighbours 5Ghz network, just not mine. And yes I thought that should have been the case as well, but the instructions actually said to do it the way I did. Is it worth trying again, installing the driver first before plugging the device in? Edited by benanna88, 23 January 2019 - 0606 PM.

Also, if the software includes a "control module" from the maker for the dongle where you'd get an icon in the system tray or overflow notification area, these very often give you more information about what the device "can see" than Windows does. This device certainly should be able to see both 5GHz and networks. I will say, though, that in my experience 5GHz networks are far less robust as far as signal strength as distance from the access point increases. I stopped using them in my household because I got a more consistent and generally faster, as a result signal on the network. If it still doesn't see the 5GHz network try moving closer to your access point just to test to see if it eventually shows up. Every WiFi card or dongle seems to have it's own level of sensitivity to signal strength and, in fact, there are settings related to same.

At the moment the original dongle is working quite well, although not perfect, and so I am sticking with it. But if I run into more problems I will try doing a full uninstall and reinstall of the new device's software before plugging it in, and see if that makes a difference. And I'll check out the control module as well if necessary. Thanks for the tips. Back to top 15 lngo lngo Members 1 posts OFFLINE Local time0536 AM Posted 19 June 2022 - 0421 AM I found this old thread. After succeeding, I'd like to share my experience. System is Windows 10 Pro, Version 21H2, Build Asus Mainboard with USB Wifi-Stick is a Realtek 8812BU Wireless LAN USB NIC, from eBay as "WLAN Adapter USB Stick 1200 Mbps WiFi Dual Band 5 GHz Antenne PC Windows 10". Wifi wouldn't work, after a few minutes heavy packet losses, most times only recoverable through restarts or adapter deactivation-activation efforts. Therefore Read forums, tried out with countless restarts, off course - Original drivers from - different usb slots - group policy automatic diver update deactived - Energy savings deactivated within driver configuration as well as system policy for usb devices and wireless adapters Wifi worked perfectly with previous setup old router as repeater and connected to ethernet port as well as with all other devices in the household. Only thing that worked finally limit device to wireless mode IEEE 11 Mbit/s. I assume the chipset itself is glitchy since many people report that problem. I'll return this POS and have ordered myself something which seems to have another chipset Netgear A6120 AC1200. Back to top
