Ubuntu Networking :: Wireless Networking - Signal Very Poor
Feb 21, 2010
My mother has Windows Vista and i have linux ubuntu. She has a special verizon card that she inserts into her laptop for internet. My computer also has an internal wireless card, but the signal here is very poor. Supposedly, among windows computers, I would be able to get a flashdrive, and with a little program uploaded from my moms computer, set things up using the flashdrive on my computer to share the internet that she pays good money for =/ However, it wont work with ubuntu, which isnt in the windows inner circle. When I open the executable file with WINE it says that it cant run wireless network setup "on this version of windows". lawl. I was wondering, is there any way around that? Is there anyway to network with my mothers internet?
iwconfig shows that the bit rate is 130Mb/s and link quality is 98/100. I'm using the wcid network manager instead of defaul gnome one. I'm getting lots of packet loss and performance is very bad. The connection is practically unusable. I've tried installing the compat wireless backport package but that did not work at all.
My wireless is flakey -- dropped connections, poor speed, etc. As diagnosis, I loaded the 'wavemon' utility so that I might watch the radio and signal and noise.Things will be good, then fall off, then get better, then go away entirely. Repeat continuously and randomly. For these experiments, my laptops -- more than one -- are on a table.The table is roughly 15-20 ft laterally from the access point. The access point is also 8 ft above the floor vs. 3 ft table height.(grin) While the signal "wobbles" everything else is mechanically stable and otherwise not moving.
I installed WICD because I was looking around the internet and the Ubuntu forums said that it was the best fix for the Network Manager not working. I added the source and installed the package like the Ubuntu site said. I go to Applications => Internet => Wicd Network Manager. It says no wireless networks found. I know that the router is working because my sister is right here next to me playing Maplestory on her laptop! When I do the lshw -C network function in the terminal it is only bringing up two things: the network controller and the ethernet controller. I used Yahoo Answers as my first goto and the answers there said that Linux doesn't have the drivers for the router. I have a Netgear Wireless-N 300 Router WNR2000 and a Dell Inspiron 1750, if that helps. Can someone give me a link to the drivers or tell me in detail what to do?
I have Ubuntu 9.10 a dell laptop i am using a tew-644ub usb wireless adaptar and it's seeing signals but wont connect to any my network is unsecured and open. everytime i try it does this swirlly thing then says diconected. im using a diferent computer to post this so if there
For the past few months I've been using Ultimate Edition 2.3 on my laptop. Various problems I encountered convinced me to switch. I installed Ubuntu 9.10 today and after the install I can't pick up my wireless router on the list of available networks. I'm able to pick up every other one on my block, just not my own. My server and my roommates laptop can pick it up and are connected to it, the problem seems to be exclusive to this laptop with the fresh install on it.I tried the 'connect to hidden network' option and it doesn't connect, it just keeps asking for the psk
For some reason my laptop cannot keep a connection with any wireless signal. I have tried several networks and resetting the router and it just doesnt work. Im not sure why...i have selected to connect to a certain network and it either takes forever to finally connect or doesnt connect at all. also when it does connect it only last a few minutes, meanwhile using win7 i have no issues with the connection.
I just installed the latest version of Linux on my Dell Mini 910 and it's now not picking up my wireless signal. The wireless card is enabled so I'm not sure what's going on. Btw, I tried entering the smb command that was given to the other member about 4 threads down as he had the same issue. Didn't work though.
My laptop has sat in the same area for days, I've noticed that in Ubuntu I get a real low signal and can barely connect for a minute and on Windows I get like 3/5 bars. I don't understand what's going on. Is it a driver issue or something?My wireless card is Realtek RTL8187B and using the latest Ubuntu as of today.But just so everyone knows, I have google'd and search around for a few hours. I've seen many different types of problems that just wasn't like mine. Lots of people can't even get theirs to work and some people use different types of drivers. But Ubuntu detects my wireless card fine, I'm just having a signal strength problem. Because the Windows on my laptop has a much stronger signal as stated above.
Im looking for a device that connects via usb in order to greatly increase the range of my wireless adapter card. It must support g and n channels. Ideally if the device need no config, that is if its 'plug in and play' would be ideal. Though if theres support in the ubuntu drivers tool that would be ok too. Im based in europe as well so it has to work here too.
Also looking to find a wireless adapter that supports packet injection on ubuntu-again with a device that needs no drivers or has drivers in the repos.for the record im looking to use these for penetration testing of a network i own.
I just installed Fedora 12 on my EEE PC has weaker wireless signal that I have previously had with any other linux distro or windows.Has anyone else had this problem, and is there anyway to increase to wireless signal?
Is there a way to keep a wireless AP from generating an RF signal at all until it gets pinged by a client which:
1) Knows it's (the AP's) IP, name, passcode, and operating port,
2) Knows which frequency, and periodic ping-rate to use,
3) And, identifies itself not only appropriately, and timely, but only pings twice before it falls silent, awaiting a response, all others would over run the limit, and thusly fail the AP screening and the AP would totally ignore them, logs the attempts, and stays cold, dark, and silent.
In short, only one (1) device is capable of turning it on.
Seems to me that conceptually, it's quite do-able. Has it been done?
I recently moved to Beijing and am having trouble with my apartment's wireless setup. My laptop can connect to any wireless network I find out in Beijing but not our home network. My Roommate has a mac laptop and has no issues connecting to our wireless router. It appears to connect but receive no signal, which is frustrating me to no end. Here is my spec list and the model of wireless router we are using.
this isnt happening on ubuntu but I think this is more or less a kernel problem that could happen with any flavor. After a new install off of a live cd my wireless card is not picking up any signals...i was able to use wireless while using the live cd but now after it has been isntalled to the hard drive it is not working. even tried in terminal to manually look (iwlist wlan0 scan) but it isnt picking up the signal
I am among those unfortunate wretches with an Atheros wireless card (ar5001) and I've had problems with it from the day I installed Ubuntu. I've been using Madwifi to connect to the internet, and it's worked fine, until I lately changed my internet connection, got a new modem etc.
Madwifi works still, but the signal is really weak - while not so on Windows Vista.
I know it's NOT ipv6 related. Do I have to change the connection settings? Is my card outdated or whatever? Am I using inefficient drivers? Should I just not use Madwifi and rather something else instead?
(Trying to install ndiswrapper and get it to work was a dreadful process, so I won't attempt that again.)
Situation is a cable modem and a Belkin F5D8235 Wireless-N router (and a computer) are at one end of the property. Approx 150-200 ft away I want to put 3 desktop computers none of which have a wireless card or device. I DO have a Linksys WRT54G I'm not using.I want to hardwire the 3 desktop computers to a switch that is hard wired to the Linksys. Putting a wireless card in one of the 3 computers is not practical because of physical obstructions (a lot of cabinetry, furniture, walls) that the Linksys (which can be at the window) would not have to deal with.
Is it possible for the Linksys to 'receive' the wireless signal from the Belkin so the 3 desktops can share the internet? If not, what could I put in the window to 'receive' or 'repeat' the wireless signal?I know this isn't exactly a Ubuntu question, except that 2 of the 3 computers are 64bit Lucid.
I have a new Acer Aspire One, model D250-1958. It uses the Atheros AR928X. I've tried Ubuntu Netbook Remix 9.10 and Ubuntu Netbook Edition 10.04, as well as the conventional Ubuntu. Everything works beautifully, except no wireless. The netbook picks up the signal, but when I provide the Key it fails to connect, and eventually prompts me for the key again.
I've tried to research this on my own, but haven't found a solution. In particular, the solution reported by narnie for his Acer Aspire One D250-1584, <HERE>, didn't work for me.
I'd really like to get this working. The netbook will be much less useful if it can't make use of our wireless router.
I'm trying to connect to the wireless netwrok of my university, which does NOT require any password. When the computer starts is automatically connects to the network and it always worked well, but now a message appears that says "authentication required" and it says that the network requires some sort of password or key. This is weird because it had never given me the problem. The options in the box are "Cancel" and "Connect", but "Connect" cannot be marked. There's also a dropdown box in the box that says "Security Type" and the option is "none". No other option is available for marking. After canceling the message and trying to connect like 50 times, I finally got a very poor connections. My email took forever to open and I opened the terminal to download something that someone said had solved the problem
Code:
sudo apt-get install linux backports-modules-jaunty
But it has taken forever to download, which proves the connection is working but it's in really bad shape. Any hints on how I may solve this? I read several bug reports and fixes similar to the problem, but they were very old (apparently a bug that was in Gutsy and then continued in some cases in Jaunty).
EDIT: Now I definitely can't connect. One strange thing was that at my house I couldn't connect either, but this time because I didn't even had the wireless option available anymore. I went to Hardware Drivers and realized 2 things:There were 2 drivers recognized, which is weird because I had always had only one, which is the Broadcom STA Wireless Driver, and there was another one, also wireless related,. but which name I don't remember Both drivers were deactivated, which again is strange because the STA was always activated before.
I activated the STA driver only. because I feared that two activated wireless drivers may have conflicted with each other. The Wireless started working again and I connected to internet with no problem. My home connection, by the way, needs a password.Now, back in University, whose wireless does not need password, the same problem happens. It says "Authentication required by wireless network" "Passwords or encryption keys are required to access the wireless network 'UC'." The a dropdown box with the title "Wireless Security" and with the only option available marked: "None". The the options in the dialogue boz are Cancel and Connect, which cannot be chosen.
ok, we had to move one of our databases due to failing hardware. This box is newer than the old but it's just dog slow. 1st I thought it was mysql but now I am realizing it's the network. As a test, I tried copying a remote file to that box and the old server (located at the same co-lo, same provider), same switch, etc.Here are the results;
Old server: access_log.1 100% 4192KB 1.4MB/s 00:03
New Server: access_log.1 100% 4192KB 72.3KB/s 00:58
So now I see why people were complaining about webpage load times, etc. I can't figure out why the network latency. I looked around a bit, see below for some things, I thought mtu, nic speed, etc.
mii-tool shows; eth0: 100 Mbit, full duplex, link ok eth1: 100 Mbit, full duplex, link ok[code].....
Are there other things I can type to test or provide more feedback somehow to get more information.
I use chrony on my laptop thinking it would be better for it than ntp because I'm frequently connecting and disconnecting from wireless cafe access points and going in and out of suspend mode. But I've also noticed that if chrony is started before the access point is connected it never syncs to the time servers. I have to manually restart it via the service command after I connect. This doesn't seem right to me, if chrony fails to find a network at start time, doesn't it periodically try again ?
I was running windows vista 32 bit (NOW UBUNTU 9.10) on my custom built pc with a TP-LINK TL-WN353GD wireless pci card, before on vista my wifi signal strength would be in the low 70% range with a speed of 54 Mbps from a access point roughly 250 yards away, now with ubuntu 9.10 signal strength in the 15-20% range with a speed of 1 Mbps. My question is, what is the best way to overcome this wifi signal strength and speed problem, it is a noticable performance disadvatange easily seen on a website like ..... where as before videos would play 95% of the time without having to stop and catch up, would a different wireless pci card be a better choice than what I have, or is the problem in the software as in a driver incompatability or lack of correct driver, not sure how to remedy the problem.
I installed 10.04 1st by making a partition with bootcamp on MacOSX.Then I formatted the partition according to Ubuntu's instructions. I didn't install rEFIt, because I prefer to just hit the alt (option) key.I made the necessary adjustments according to URL...Community Ubuntu Documentation - and everything seemed to be working fine.I upgraded to Maverick and everything seemed to be working fine aswell.But then I noticed, that the wireless signal keeps failing and I'm asked to put the password again and again..
I don't think this is due to the upgrade from 10.04 to 10.10, but I just noticed it recently, maybe because of the air humidity, the signal was stronger a few days a go.. don't know!!Is there anything I can do?Perhaps install a new driver, or another wificlient, like Wifi-Radar??
i'm surrounded by concrete block wall but have found an unlocked wifi signal. but i need to do something to help boost the signal. my HP laptop has a built in wifi card and i'm looking for something that i could use or do to help boost the signal.
I just installed 10.10 on a Dell Inspiron 1300. The wired connection(eth0) works fine but I get no wireless signal when I unplug and try to connect to my network/internet. It shows that wlan0 does exist but it gets no signal. I've used the rfkill to make sure that it wasn't blocked and everything seems to be ok, except I get no wireless signal.
I uninstalled Network Manager and installed Wcid and it found nothing. I even tried installing several signal scanners I found in the package manager. I've removed, updated and reinstalled the broadcom drivers. I still get nothing. The wireless signal from my router is nonexistent according to Ubuntu.
The wireless works fine when I put my windows XP HD in and it also works fine when I put my Mepix or PCLinux OS HDs in the laptop. So I know that the wireless card is not busted.
I'm using 9.04 on a laptop .when i was useing windows I got strong full bars for the wifi signal strength. On the same laptop in the same location, I get only 2 bars (low) wifi signal strength when I'm in Ubuntu 9.04 I'm using the wifi transceiver built into my hp Anyone heard of this problem?
