Debian Hardware :: Cut Power To WiFi Adapter On Startup?
Aug 26, 2015
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?

im using fedora 10 with gnome on a laptop, i want to increase power to my wifi adapter as im only getting 40% connection strength to the nearest wifi AP (about 20 feet) in windows under power management there is a slider with best performance against battery life, is there a similar setup in fedora 10? ps, if explained fairly well, i dont mind shell scripting (bash) and compiling.

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,
Code: Select all[ 5478.544704] RTL871X: reg 0x80, usb read 4 fail, status:-71 value=0x0, vendorreq_times:1

I'm somewhat new to Debian and I'm not sure what else to do here.

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 mac80211 probe_wait_ms=1000 or Code: Select alloptions mac80211 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.
Output of commands on Debian 8.0 64-bit (I edited out some info, MAC, ...; not sure if that is important):

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

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 have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

i tried following the readme file included in the driver of the usb network adapter but seems its not exact.
any ideas on how i can configure it manually? KDE does not detect any wifi device. .(of course since no driver is installed yet).
i used my desktop (win***)with DSL connection and installed the driver of the usb net adapter.. made it as the access point. . so my laptop detects the desktop as wifi spot.

I recently installed Ubuntu 10.10 onto my Acer Aspire D260 netbook.I find it much easier to use than Windows 7.Everything has been working fine until I recently tried going on the internet via battery power instead of my A/C charger. My update manager is showing that I am up to date and Additional Drivers is showing that the Broadcom STA wireless driver is installed and in use.

I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?

Having moved my computers into a "new" office in my house, I have no network cables. Had fun times trying to run a network cable, ultimately stopped due to unknown block in the vertical wall and fear of drilling through something important. I have strong WIFI signal to this room.
I tried plugging in my Netgear WPN111, didn't work. Works on my Win7 box, and I need one on that anyway, so I'd prefer to get another wifi card, be it a PCI, PCIE, or USB dongle. I would prefer the USB dongle since I could then use it elsewhere if need be. I've installed Ubuntu 10.10 64-bit. The cpu is an Intel quad-core 920, with 8GB ram.

Out of all the Linux I have tried, this is the only one which will hibernate and startup again properly. But it has no drivers for the rtl2860 wifi adapter. I am thinking of using NDIS wrapper, but it may stop hibernation working. I see a guide which I am going to try to follow, but has anyone out there got this adapter working and hibernation still works?

I Have an HP Pavilion G6. I recently installed openSUSE after having no luck with another linux distribution. I was told openSUSE is more compatible with laptops, so I figured I'd give it a try. I am now facing the same problem I had been facing w/ the other distribution (Ubuntu). My Network Adapter doesn't seem to be recognized by any linux operating systems. It is a Ralink 802.11b/g/n WiFi adapter. When I open the "network" tab, my home wifi is not listed, nor are any around me. In fact, I can't even open the "wireless" tab.
I've installed any recent drivers for my adapter, and I went to extensive lengths to try to solve the issue on my previous linux distribution. I don't know what output to give you from the terminal, nor do I really know any commands to look for anything. On a side note, I had been messing with my touchpad application, trying to set my preferences. I check the boxes for horiz. and vertic. scrolling with two fingers, and apply. They don't work. I check the boxes for using two finger tap to do something, and three finger tap to do something else.

I started yesterday off wanting to install this USB wifi adapter on my PC (which is mini-itx so has additional pci slots) [URL] it has the Ralink 3070 chipset. I tried everything I found when googling, nothing came close to working, this was in Fedora12. So I gave up and installed Ununtu 10.04, hoping for better luck there. Ubuntu will recognise the presence of a wifi adapter, here's the output from iwconfig
[Code]....
But it sees no wifi networks and generally won't do anything; I don't think it has the right driver. Rosewill does list a (linux) driver and so does Ralink, but again, neither of these come close to working. has anyone gotten this adapter or chipset to work in ubuntu?

My laptop has an internal wireless g "adapter" (for lack of a better word) and I plugged in a very cheap and very small ASUS wireless N adapter later on. The ASUS adapter has better bandwidth (again for lack of a better word) but isn't as high quality of a link as the internal adapter is.The laptop appears to be using the internal adapter, but i want it to use the ASUS adapter.

I am using a Sealink PN 2202 USB serial adapter on a linux box (Ubuntu 10.4) running kernel 2.6.32-28-generic. I have written a perl script to simply log the incoming RS232 data (9600 8N2) and it works fine when I start it from a bash shell:
perl /home/pk/PerlCode/RS232_D4_v11.pl
However, I need the computer to boot and start logging after a POR. If I try to use Startup Manager to execute my script everything seems ok but I randomly loose about 20% of the incoming RS232 data. In Startup Manager I use the command
gnome-terminal --title="D4 RS232 Log" --execute bash -c "perl
/home/pk/PerlCode/RS232_D4_v11.pl"
If I close the automatically-started script and restart it from a bash shell, I again will randomly loose about 20% of the incoming RS232 data. It almost seems like I have screwed up the driver by using the Startup Manager. The only way I can get reliable logging again is to remove the script from Startup Manager, then restart the computer and manually launch the perl script. I was thinking that maybe the order in which the driver was loaded and perl script started might be an issue. So I tried a bash script that sleeps for 15seconds, then starts the perl script. Again, I loose random pieces of incoming data when this is initiated by Startup Manager.
Here is some more info:

After a new fresh-from-DVD install of Fedora 14 64-bit (over top of Fedora 12 64-bit which went over top of Fedora 10 64-bit before that) my Linksys WUSB600N adapter connects at login to my WiFi N router with WPA2 Personal.
That is great, as previously (fc10/12) I had to use the Ralink drivers per ogetbilo's thread on this forum (that thread kept me on the net for many years now). And at some point this even became a pain because sometimes the system would boot and refuse to connect to the wireless (which would hang trying to connect) and then crash to a dump screen on shutdown (bug reported). The fix was hoped to be found in upgrading to F14 and the newer kernels with working native Ralink chip support.
But I still have an issue... the connection stays up for a few minutes then drops. If I disable/re-enable wireless it (at least sometimes) re-connects. But obviously that is not workable. This is a USB adapter and I am not entirely sure that there is not some USB powersave issue going on, but I do not see anywhere to disable system USB power saving either.
