Debian Configuration :: USB Wifi Adapter Frequently Disconnecting
May 20, 2015
Using a USB ISO, I recently installed Debian 8.0 Jessie (64-bit, Xfce DE) to a new computer. I usually lose my Wifi connection after 1-3 minutes when donwloading/uploading at around max. speed 4 Mbps/512 kbps. Sometimes it will last 15+ minutes.
When lightly browsing it can usually stay connected for 15-30 minutes. I have to disable and enable Wifi using NetworkManager to connect again. If I remember correctly, there were problems with the Wifi connection even during the installation of Debian.
This Wifi USB adapter works fine on my old computer with Debian 7.7 (32-bit). No problems with the Wifi connection yesterday on my old computer during 10+ hours of activity.
This Wifi adapter also works fine on this new computer when I boot from a live USB (Rescatux 0.30.2) downloading and uploading at max. speed for 1+ hour.
I already tried some suggestions I found online, but they didn't work:
* changing Wifi channels between 1, 6, 11 in my router settings
* changing WPA-WPA2 to WPA2 in my router settings
* ignore IPv6 in NetworkManager
* change probe_wait_ms from 500 ms to higher value by adding Code: Select alloptions mac80211Â probe_wait_ms=1000 or Code: Select alloptions mac80211Â probe_wait_ms=3000 to /etc/modprobe.d/mac80211.conf and rebooting
* disable Power Management for Wifi adapter (not supported)
* ...
I can also post the output of commands from Rescatux or my old computer if needed.

I installed vpnc package under RHEL 5.1 64 bit and its working fine. but it is showing frequent disconnectivity issue. I did added the script for respawning:

I have just added but no idea if it will work or not.Downloaded from external source.
1. How to check vpnc logs upon disconnectivity? 2. How to make the connectivity stable?
My wireless card disconnects frequently and sometimes it won't even connect at all. I've googled the card and the driver and it looks like others are having similar issues as well. [url]-[url]
My lspci | grep -i network is as follows
Code:
Under iwconfig, it's identified as wlan0, and I'm running kernel x86_64 2.6.32.9
i'm very new to linux(starting), don't know anything. I tried my level best to configure my wifi adapter but, couldn't do it. so give to step wise instructions to to do so.
I want to know any command which is equal to disconnecting and reconnecting lan cable. actually sometimes my router takes some time to connect to internet and when this happens my desktop shows network disconnected. but when router is connected system does no detect it and i have to manually disconnect and reconnect the cable which is not convenient.
I have another thread started [URL] asking for support on configuring a Netopia TER/GUSB-N USB Wireless Adapter. But, I figured it would be interesting to get some opinions about other wireless adapters. I don't mind shopping on eBay for a new adapter or purchasing one at Walmart or BestBuy. So basically, I wanted to find out which wireless adapters are guaranteed to work out of the box after installing Debian. I am setting up webcam servers throughout my house and want to use the same hardware as much as possible. So if anyone has any recommendations on a wireless adapter that is proven to work and work well, please let me know.
Here are three that I can get pretty cheap at Walmart: Belkin N150 Enhanced Wireless USB Network AdapterNetgear WG111 Wireless-G 54Mbps USB 2.0 AdapterCisco - Valet Connector (Wireless N USB Adapter) AM10-4A
The usb wifi adapter (airdata 150 s2 usb) which I have don't work well. The first time I put it on my computer does not work, so I installed this package [URL] but still not working. Then I search on intenet and found how to make it to work here [URL] that I do is add "blacklist rt2800usb" at the end of the file /etc/modprobe.d/blacklist.conf . After that usb wifi worked, but I have others problems. Some times it disconnect from the Internet and web pages are loading slow and some times do not load at all. Does any one know how I can make it work well? I am using Debian Squeeze.
I bought this wifi adapter to use with my home server running debian Wheezy [URL] ....
I installed realtek-firmware and wireless-tools(including NetworkManager and wpasupplicant). I rebooting and plugged in the wireless adapter and it didn't load the driver. After further research, I found that this adapter required the RTL8188EU driver, which I had to install manually. After manually installing that driver using the source from the iwfinger github [URL] .... and rebooting, I plugged in the wireless adapter and it worked. The wireless adapter seemed to work but after testing it under load(downloading a several GB file from the server and uploading a several GB file to the server) I ran into issues during the tests. I'm not sure what is going on but it seems the driver is failing or it is disconnecting from the network. I checked dmesg and this is what I found,
I dual-boot Jessie with Windows 10, and I recently guessed that the 'fast boot' (hibernate on shutdown) feature of Windows doesn't properly shut down the RTL8188EU NIC plugged into my PC. So when I boot into Debian, it isn't properly recognised by the driver and I have to completely shut down the PC to make it work.
Is there a way to automatically cut the power to the wireless NIC on startup and then reenable it so I don't have to do this?
Its been like this since fedora 12, in fedora 11 its no problem, i hope it will be fixed in fedora 13 and i am waiting..., and after fedora 13 released the problem is still the same...
I use Intel 3945ABG. wifi connect with no problem and after few seconds its disconnected, and re-asking my saved password (which is stupid since i save the password so fedora won't ask me that stupid question again).
Wifi seems to disconnect fairly requently, sometimes reconnecting automatically and sometimes requiring me to re-enter the wep password.
I would like to make it so it stays connected.
The router is not very close, but I think it's close enough. I even moved it closer. Other devices (such as my N900 mobile phone) hold the connection without issue.
One complication is that there are several devices all with the same SSID, though there should be one which is clearly stonger.
I never had this problem with Ubuntu before and I am now confused. This is a clean install and I have not change anything about my AP so don't why this is happening.
Every 5min or so my wifi keeps disconnecting and sometimes have problems reconnecting. I also have Windows on this machine and it does not do this at all. My AP is set to channel 9(changing it makes no difference), WPA2. Logs below

-i have a HP Pavillion dv6 entertainment pc laptop -im using ubuntu 10.10 -my wifi indicator keeps flashing -before when i was using fedora this was not happeneing -and now some times in between wifi disconnects and doesnt connect back -only after restarting it connects back -anyway its not disconnecting very frequently -but when i put something for downloading in the night, morning i can find it incomplete as wifi got disconnected -same time my netbook using windows xp keep working and connected
I have Lenny running on my old Toshiba Qosmio E10 via wired ethernet. what I need to do to get the intergrated wireless adapter recognised, configured etc.
I just did a Wheezy reinstall (I just started using LVM on LUKS), but my Ralink RT5370 usb wireless adapter wouldn't work, even though I have firmware-ralink installed. When I click on the Network Manager icon, it lists my home network (WPA2 passphrase) as available, but clicking on it yields no result.
Before the system reinstall, I've been using the adapter with firmware-ralink without problems. As far as "apt-get update && apt-get upgrade" goes, my system is up-to-date.
I tried uninstalling and then reinstalling firmware-ralink (rebooted too), but to no avail. The adapter seems to be undamaged.
Here are a few pieces of info that might be useful:
Code: Select all$ uname -a Linux watershed 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u1 x86_64 GNU/Linux

Wifi getting disconnected very frequently in Fedora 10. I am facing issues in my Toshiba satellite laptop, after a fresh install of fedora - 10. After the install, The wi fi connection is dropping off very often, and even on keeping wpa_supplicant and wifiroamd in "active" state, the connectivity needs to be established manually.
I've just installed Debian Wheezy on my old Toshiba Satellite A10 (Intel celeron 2.20 GHz, 1GB Ram, 30 GB hard drive) and tried to connect to my home wifi network with a usb wifi adapter (Hamlet HNWU254G). lsusb in terminal says it is Ralink RT2501. Ethernet worked fine, so I installed firmware-ralink package, the adapter was recognized and I was able to connect.
However, I heard quite frequently a strange whistle and realized it came from the usb wifi adapter; it also got very very hot. Other strange thing: the computer some times freezes: screen flickering, loss of control of mouse and keyboard, need to shut down with power button.
At first I thought it was the video card not being powerful enough for Gnome (even classic), but then I installed Xfce4 and nothing changed. Instead, when working offline, freezes happen less frequently (but still happen).
I've tried the usb adapter on another laptop with wheezy: it gets hot, but there are no whistles and freezes.
I'm running Ubuntu 10.04 64bit on a 15' Dell Studio After doing an update my internal wireless will not connect to my wireless network. The card is on, I can see networks around me, but it will not connect to mine. It just acts like its connecting and then disconnects.
i am using broadcom wireless (4312) on my laptop with FC15 and configured it using [URL]. initially it ran great without any problem (for a week). but from yesterday, every 15 minutes or so, my wifi started getting disconnected, showing the wireless login screen . I can reconnect only by rebooting or restarting network manager service.
I should be able to access xfinitywifi hotspots. /etc/network/interfaces and /etc/wpa_supplicant.conf. I don't want to use NetworkManager for this connection.> iw dev wlan0 scan
Apparently, the wireless adapter Realtek 8171 uses the rtl8192se driver, which is currently available only as source from Realtek's website. Is building a driver equal to building a package? Should I follow the same cautions, say these ones?
I've followed the guide at URL.... but my computer is unable to find any Bluetooth devices. Whether I'm using the command line or gnome-bluetooth, I don't get any results. If I plug in a cheap USB adapter, I'm able to connect and use the devices.My computer is a HP ProBook 4330s running Debian Jessie. And as far as I can tell the Bluetooth adapter is a Ralink rt3592 combination Wi-Fi and Bluetooth PCI card. The Wi-Fi works fine, but when i try to connect to a Bluetooth device, I get no search results.
I'm going to start using Debian as my desktop system rather than Ubuntu since I'm not really liking all the crazy eye candy and just wanted a fast and simple system. My main problem is networking, I guess I'll start off with my system specs and other information for problem solving.
I have a Realtek RTL8111/8168B Ethernet Adapter builtin to my motherboad which I am using, I could only get a basic connection, by basic I mean that it allowed me to connect to my local area network but not the internet. I then modified /etc/NetworkManager/NetworkManager.conf to change to managed=true this allowed me to use the internet, but the problem is, that it is a very unstable connection, the speed is very slow and it drops a lot! I have to carry on running /etc/init.d/network-manager restart twice to get my connection back, which lasts for about a minute.
My pc is aser aspire 5735z. I have acer nplify 802.11b/g draft-n wlan but i can use wifi on debian what i have to do ? Do i need driver or firmware? how can i solve this problem ?
I did a netinstall earlier today (latest version, amd64) on my Dell XPS laptop and ended up with a minimal installation because I couldn't connect to the internet. Now I'm trying to get online without a desktop environment.
I have an Intel Centrino 1030, so I downloaded and installed the firmware [URL].... with a usb, then rebooted. My searches have turned up a lot of instructions involving a utility called iwconfig and wpasuppliant, but these are apparently not installed. I don't really know much about it, but my /etc/network/interfaces file looks rather empty:
Code: Select all# The loopback interface  auto lo  iface lo inet loopback
Shouldn't there be something like wlan0 there? The network card does show up with lspci
I've been installing multiple versions of ubunutu over years and now I better understand why I faced always problems with wifi configuration on these different baselines : Debian root of course.
Now on Debian 7.4 : The Broadcom BCM4313 driver is not loaded by default (not free product) for my wifi card. This is stated thru the UNCLAIMED declaration
Code: Select all sudo lshw -c network  *-network UNCLAIMED     description: Network controller     product: BCM4313 802.11b/g/n Wireless LAN Controller     vendor: Broadcom Corporation     physical id: 0
[Code] ...
Unclaimed means : no driver found (no kernel association)
So I installed the driver located in the non-free backports by adding this target into the repository
Code: Select alldeb http://http.debian.net/debian/ wheezy main contrib non-free
 *-network     description: Wireless interface     product: BCM4313 802.11b/g/n Wireless LAN Controller     vendor: Broadcom Corporation     physical id: 0
[Code] ....
I can't connect with wlan0, it doesn't work. I found information here regarding WPA2/PSK wifi configuration on debian : [URL] ....
so I added this setup to my interfaces file an got :
Code: Select allauto lo iface lo inet loopback
allow-hotplug wlan0 iface wlan0 inet dhcp  wpa-ssid Hznteam-Datacenter  # hexadecimal psk is encoded from a plaintext passphrase  wpa-psk 12345678901234567890123456
It's worth ! no more wifi network are detected and ifconfig gives no ip address allocated :
Code: Select allwlan0   Link encap:Ethernet HWaddr 78:e4:00:4e:49:a3      UP BROADCAST MULTICAST MTU:1500 Metric:1      RX packets:0 errors:0 dropped:0 overruns:0 frame:0      TX packets:0 errors:0 dropped:0 overruns:0 carrier:0      collisions:0 txqueuelen:1000      RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
In a hp pavilion 15 Notebook PC with Debian 8.1.After two hours or so wifi stops working. Network-manager does not give any indication of failure but some times a yellow question mark.
