Estimable
I am using an Acer Aspire V3-371-59YR laptop. Processor: i5 4210u, RAM 8 GB, WiFi adapter: Qualcomm Atheros AR5BWB222, Windows 8.1.
Whenever I connect to a WiFi network, it always shows «Conneting to the network is taking longer than usual». Honestly, there is nothing unusual about that. It shows me that warning EVERY. SINGLE. TIME! But the internet works just fine. The problem arises when I plug in the laptop. The wifi suddenly stops working, mysteriously. Sometimes it disconnects completely and shows me a yellow triangle with an ! sign on my network icon. When I try to connect to the wifi again, I get the «Cannot connect to the network» error repeatedly. Sometimes I let a page to load and immediately plug in to see the response and the page loading just haults. If I unplug immediately after that, the page load magically resumes (BTW it is impossible to connect to Wifi while my laptop is plugged in. I need to disconnect and reconnect the adapter plug while connecting to the network and this sometimes works). I have tried uninstalling drivers, reinstalling, switching between the drivers made for the adapter by microsoft and qualcomm, updating the drivers, messing up the power settings, reseting my adapter, toggling airplane mode, setting «enable downloads on metered connections» (even though my network is unmetered). I have tried with various routers and networks, tried changing WPA2 security to WEP, disabling it altogether, restarting the computer, doing all sorts of stuff I have been able to find online, but no fix ;_;. This is definitely a software bug in Windows 8.1 or in the driver as nothing else works. PLEASE HELP. PLEASE! I am stuck!
Update 1 March 28:
I have applied some patches provided by acer and have also updated my bios. Now I am going to try again. Let’s see.
Update 2 March 28 (after few minutes):
It seems to work for now. Maybe I fixed it, maybe.
Update 3 March 28 (after few more minutes):
It works now, YAY! But I still get «the connection is limited» and «connecting to network taking longer than usual». Any help?
Wifi starts and stops
Hi,
I’ve been able to run wifi with a Neatgear (Realtek RTL8188CU), and make it start at every boot.
But since three days, I’m getting crazy, wifi starts on boot (blue dongle led blinks and I can scan the wifi ip adress) but immediatly (about 1 or 2 mn) it stops without any reason.
Any idea.
Thanks by advance
Re: wifi starts at reboot but stops 1mn later
FYI:
/etc/rc.local:
_IP=$(hostname -I) || true
if [ «$_IP» ]; then
printf «My IP address is %s\n» «$_IP»
fi
modprobe snd_bcm2835
echo «Starting WiFi. »
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
sleep .5s
dhclient wlan0
echo «WiFi should be started»

Maybe this will help to find the glitch..

Re: wifi starts at reboot but stops 1mn later
It will be a cruddy power supply.
Try one that can reliably deliver 5V @ 1A or better.

6 Reasons Your WiFi Keeps Disconnecting and How to Fix It
Whether you’re in the final research stages of a major paper, on a Zoom call for work, or simply gripped by the season finale of «Ozark,» a dropped WiFi connection at an inopportune time is a massive buzzkill. People deal with this modern inconvenience all the time, sometimes for months before doing anything about it. Here are some of the most common reasons it happens and what you can do about it:
1. Too Many Devices Are Connected
Back in the day, the average household had a computer or two to connect. Now, with smartphones, iPads, smart TVs and so much more, it doesn’t take long for WiFi to hop aboard the struggle bus. «Surprisingly, even if a connected device isn’t actively sending/receiving data, it will still consume some of the available bandwidth,» says Neil Parker, chief technical officer and co-founder of the livestream wedding app Lovecast, in an email. «What this means is that if you have many devices connected, you can start to see slowdowns or drops in your WiFi connection.»
The Fix: Parker says that the first and easiest fix is to disconnect unused devices from your WiFi. The easiest way to do this is to simply change your WiFi password, which will kick everyone off. Then, you can allow only certain devices to rejoin. «If that’s not feasible, you can also try to switch bands (maybe connect to the 5 GHz band instead of the 2.4 GHz where it may be less crowded),» he suggests. In general, the 5 GHz band has faster connectivity but a shorter range than the 2.4 GHz band, which has a longer range but can be slower. Change the band by going into the individual device’s settings.
Cutting back on heavy WiFi use temporarily can also help — for instance, stop gaming or downloading a movie.
Finally, you may need to upgrade your connectivity. First, run a speed test to check your current speed. (Google «speed test» to see a list of websites where you can do this.) You may have too many devices connected for the internet speed you’re paying for. If this is the case, contact your internet provider about upgrading to a higher speed. But you may want to try some of our other fixes first before spending the money.
2. The Router Is in a Bad Spot
This is the most common reason for WiFi failure, says Aseem Kishore, founder of Help Desk Geek in an email. «If your access point is buried three doors down in a closet and the device that you’re trying to connect it with is edging on the outer limits of its signal range you’re going to face signal dropping till you move your device closer to the access point,» he says.
The Fix: Install the router in the room where you plan to use the WiFi most or as near as possible. Mike Dragan, chief operating officer at events app Oveit, says to elevate the router so that there aren’t any obstacles in the way and place it as close as possible to the middle of the home. «You should also stay away from reflecting objects like glass, mirrors and metal, as WiFi signals tend to bounce off of them,» he explains by email.
3. You’re Getting Radio Interference
«Most of us place our WiFi routers next to our cordless phones, Bluetooth devices and smart TVs, and this causes all these different signals to interfere with one another and eventually result in signal dropping. If you’ve ever wondered why your phone stops getting WiFi when you’re next to the microwave, say hello to radio interference,» says Kishore. Radio interference may also happen if you live in an apartment or condo building and everyone has their own WiFi routers in close proximity.
The Fix: Change the channel on which your WiFi is operating. «Use an application such as WiFi Analyzer that tells you which WiFi channels are being used the most. Pick a channel that is used the least,» emails radio engineer Sam Brown with the wireless technology blog OneSDR. «Alternatively, switch over to the 5 GHz band. In general, this is a very good solution for WiFi in apartment buildings where there can be hundreds of access points in operation in the very popular 2.4 GHz band but relatively few of them operating at 5 GHz.»
4. The Wireless Card Needs Updating
The drivers on electronic devices, like printers and computers require semi-regular updates, or else they won’t work well. If you’re struggling with WiFi drops (particularly if it’s on just one device) check to see if the device’s drivers need updating.
The Fix: As with other types of tech, you’ll have to go straight to the source to fix this pickle. «To upgrade your wireless card drivers, go to the manufacturer’s website and get the most recent versions,» emails Steve Scott, chief technical officer at Spreadsheet Planet.
5. The Router Needs a Break
People are pretty punishing to devices. We keep cell phones, laptops and all variety of digital things turned on all the time, regardless of whether we’re using them and expect them to function at peak potential. Routers are no exception to this habit, but they need the occasional time out, too!
The Fix: Turn off your router and modem and keep them unplugged for a minimum of 30 seconds, says Stewart McGrenary, director of Freedom Mobiles. Then restart them in this order: «First, connect the modem and wait for it to fully connect. Then you’ll need to switch on your router. Sometimes that’s all that’s required,» he says.
Sometimes, all the restarts and repositionings just don’t make things better. In those cases, it’s probably time for new technology. «Old routers become less and less compatible with newer services,» says Christen Costa, CEO of Gadget Review via email. «You may find it works after a reset . for a while. But eventually, you’ll need to get a newer router.» If you rent from your WiFi provider, double-check that you are using an up-to-date version. If you own, it’s probably time to bite the bullet and purchase a new one.
Thick walls are good for keeping noise out, but they get in the way of WiFi functionality. The most problematic materials in this regard are metal, concrete and brick. If you have interior concrete or brick walls, invest in a few wireless access points, then place them as close as you can to the devices in question. This will create a wireless local area network (WLAN) like those found in offices, which improves signal strength and increase the number of devices the network can support.
