Fedora Networking :: Signals Strong But Broadcom 4318 Very Slow?
Nov 19, 2009
I've got the b43 driver and firmware installed, and the system comes up fine, but the max throughput on the wlan0 is about 100Kb/s. My laptop and iwl do about 2.5Mbps from the same location in the house. The signal is plenty strong:
wlan0
IEEE 802.11bg ESSID:"sar2"
Mode: Managed Frequency:2.422 GHz Access Point: 00:23:69:22:5C:00
Bit Rate=36 Mb/s Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=61/70 Signal level=-49 dBm Noise level=-57 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Is this expected from the b43 driver and a bcm4318? I was hoping for much better throughput. Also, I tried the broadcom-wl driver, but it doesn't seem to recognize the card. It looks like it's not supported from their site, only the 4311,12,21,22 were listed, although I see posts where other people claim they are using it with a 4318?

Ok, so spec's on my setup: Ubuntu 9.10 on a Dell Inspiron 530.. Q6600 w/3GB RAM, 500 GB HD w/radion 2600xt and broadcom wlan NIC. My issue is that the broadcom will not connect to my router. I did some searching, found a link from this site detailing how to get my NIC to work on Intrepid, but that's not what I have. I followed that guide anyway, substituting my driver for his (guide is on sampbar.com) and nothing. It's showing now as not ready. I've installed ndiswrapper and grabbed the drivers for my NIC from my Vista install, but when I use ndiswrapper to do that, I get an error saying it can't tell if the hardware is present, then shows me it is present and it still won't connect.

Here is what I have as far as hardware goes:
Compaq Presario V2000
- PROCESSOR: Intel Pentium M 710 -- 1.4 GHz
- RAM 2 GB
- HD 80 GIG
- Duel booting XP Pro with Ultimate Edition 2.8 (I understand this is built from Ubuntu 10.10)
- lspci -vnn | grep 14e4 yields the following:
Code:
03:00.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
I have followed to the tee this guidance: [URL]
I tried the installing b43 drivers with internet (using ethernet)
I tried installing off the DVD using the no internet option
I even tried installing the STA drivers even though I know the 4318 chipset is not mentioned as a supported chipset.
All of these were loaded/extracted with no errors via terminal following the guidance to the letter. Now here is a problem I have not read that anyone else has run into. (maybe I just missed it). When I go: System > Administration > Additional Drivers the only additional driver that shows up is "Software Modem". I can't for the life of me figure out why the b43 and STA drivers are not showing up to activate. I can install drivers all day long, if I can't activate them, it really does become a moot point.

So I just loaded ubuntu 10.10....and it works great...except for my wirelessi've got a broadcom b43 ...i went into system, administration, download additional drivers and downloaded/authenticated a b43 driver, but my machine (hp dv4405) does not recognize any wireless signals. The wireless light on my computer doesnt turn on (there's a button to turn it on and off) anyways...it's annoying. I guess broadcom recently released some open source drivers, but I'm having trouble sorting through all the info

I am succesfully installed a Dell wireless card with Broadcom 4328 shipset using ndiswrapper and rpm sources on Fedora 12 2.6.32.14-127.fc12.i686.PAE. Now I am using original Win drivers but the wifi conection is very slow and unstable.
The wifi card runs perfectly on win 7.

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.

Why does a NIC need a permanent individual way to distinguish it? Why not give it the host name in a form that is not a permanent hardwired hardware? Seems that the last ethernet router before reaching your PC is really seeking your NIC. So why is not the expression "What is your NIC Address" instead of "What is your IP Address"?

i noticed today that the last three places ive tried to use wifi at (a friends house, my cousins house, and my moms office wifi) refuse to connect, even after triple checking all the passwords and trying various security protocols (WEP 40, WEP 128, etc.). strangely, last weekend i was able to connect to a hotel wifi signal with no trouble. even stranger, my ipod touch is able to connect to all these places. at my friends house, we even tried an ethernet cable but ubuntu didnt even know it was there. im a little concerned about this, as i might need to connect to wifi for something really important and ubuntu wont cooperate.

barley got it today in fact, have my laptop dual booted running Win7 and Ubuntu 10.04. I haven't worked with the terminal at all so i have no idea what I'm doing with this. I'm having a problem connecting to the wireless Internet. It has theicon at the top but doesn't recognize any signals. Works fine using land line though. My laptop has the wifi on/off button on it but that doesn't seem to be doing anything

I can't pick up any wireless signals while running Ubuntu 10.04, but while running Windows 7, I pick them up. I have the feeling it's because of a missing driver, could anyone help me solve this issue?

I had windows and 8.10 earlier and now have single boot 10.04 !
1.) I can see wireless networks only after I am connected to the router through wired ! I guess its some thing to do with me activating ifup and ifdown, when my wired connection stopped working as i was trying to install wireless drivers.
2.) Even when I see wireless networks, i cannot connect to any of them.
I tried various things for a whole day trying to fix it and i doubt if i screwed up some thing that was running good.

just switched from Windows Vista to Ubuntu 10.10 on my Toshiba laptop and I'm loving it, except for some wireless connection problems. About 70% of the time, my computer is unable to find any wireless signals whatsoever, despite being right next to the router. When it does find the signal it connects fine and runs great, but most of the time it doesn't show any signals at all. I can't find any pattern to when it does or doesn't find the signal. My result for the "sudo lshw -C network"

Got up this morning and switched on theLinux Box and started getting wifi connect problems. I could work for about 5 mins then it would start searching and asking me to confirm to connect to my network.After some time NM kept on asking all the time to confirm the network and key.I reset the router and check to see if other PCs were OK and a Windoze & Linux laptops were fine, no problem there so it's not the routerd.I'm wondering if the broadcomm card is starting to fail as it heats up or could it be a corrupt file or parametersNo updates have been done in the last month, it just started today. Here are the results from the log and dmesg:
[root@mylinux ~]# dmesg | grep b43
b43-pci-bridge 0000:05:01.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17

I have a Dell-made, Broadcom-based wireless card, BCM4322. I'm using Broadcom's proprietary drivers from RPM Fusion.
Code:
lspci | grep -i broadcom
09:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10)
0c:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)
Since installing F11, I can no longer connect to WEP-secured wireless. When I use automatic IP settings, the connection simply times out. When I specify an IP, Netmask, Gateway, and DNS server, NetworkManager thinks the connection properly established, but any pings time out, even when I don't specify a hostname (just an IP address). I can connect to (and use) unencrypted wireless. I haven't tried other encryption schemes. The WEP index is 1 and it's non-authenticated (open). I've been playing with the settings for over a week now with no success.

there was a new kernel update that I installed today. I used some kl mod packages to work my broadcom. For some reason its not working after the kernel. Is there a way I can recompile the driver or so?

Ive just installed Fedora 12 on my laptop (HP Pavilion DV4 1213la- i also have Windows 7) and wifi wasnt working at all (Broadcom BCM4312)So i thought, lets google it!, i pluged it to my router and i had internet working just fine.
After goggling for an hour i found a website where some guy had a problem similar to mine (couldnt connect to internet by WIFI with the same Network Controller BUT on Fedora 11)[URL] and as a response they told him to install the packages using " yum install broadcom-wl wl-kmod "So i did that, it downloaded some stuff (i didnt see what it was :S), but then said something like "No packages available broadcom-wl" and "No packages available wl-kmod"I tought it had done something so i did as the website told me, reboot my computer.
When it turned back on, not only wifi wasnt working but now i cant even connect by cable, i plug it in and nothing happens (not even the little lights from the port)So my question is, is there any way to restore whatever that command did?

I am drowning in Broadcom over here. Fedora 15 with Broadcom 4313 wireless inop. I believe that I have made every attempt to get this Broadcom 4313 off and flying that is posted on this, and many other, forums. I had the wireless working on this laptop yesterday when I made an error with a NVIDIA driver that caused me to be unable to boot. I updated/reinstalled the kernel and the fun began. Here is where things are at. note the broadcom version fc13? No idea why that would be 13.

So I've tried some hours ago to install the new kernel 2.6.38 and when I did the reboot, it prompted this error: "Error 11: Unrecognize device strong
Press any key to continue..." I know this is such a general question but how to install the new kernel with Fedora 14? I think I did compiled and configured it ok and did something that wasn't recognized by grub or perhaps when I ran the command to make the new initrd.

I can't get my Broadcoam BCM4322 to connect to a protected access point. I've tried the drivers from rpmfusion, and tried to build the module with the source+binary package from Broadcom, all with no luck. The failure seems to happen during the WPA negotiation.
I haven't tried connecting to an unsecured WiFi access point.
When booting this same laptop to Kubuntu 9.04, it can connect to secured, so it is possible under linux.
Here's output from lspci, and the tail of the log while KNetworkManager is trying to connect the device.

I chose to change my operating system from Microsoft Xp to Linux and finally chose Fedora to be my new OS.
After Fedora installation I got a problem that I cannot connect to my wireless network I used to using Xp, I think that my wireless card is not installed on Fedora because when I checked in the network configuration I found that the only installed adapter is the Ethernet Realtek for the wired connection.
My OS is Fedora 11.
The CPU Model name is : Intel (R) Core (TM) 2 Duo CPU T8300 @2.40 GHz, so I think that my architecture is x86_64.
My Network controller is : Broadcom Corporation BCM4312 802.11b/g

You know, I thought I had my Broadcom issues all figured out, I have a simple list of installing the RPM Fusion repos do a yum update and yum install kmod-wl and everything works.However, this time it didn't work. I am installing a new fedora 14 for a friend who is totally fed up with windows and I get this error: (Yes I have searched the internet and Fedora forums for an answer)
[code]...
I have tried the two yum suggestions and they don't work I have tried updating the kernel and have installed kernel-devel-'uname -r' (suggested by another site) I have tried installing broadcom-wl and b43-openfwwf which only knocked out the card entirely

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.
