Ubuntu Networking :: Slow Wifi - But Fast Connection On Network Cable
Jan 22, 2011
I have a strange problem that I cannot diagnose -- slow wifi. About two or three weeks ago, I noticed that my wifi began to slow down dramatically. The problem is the same on my ubuntu laptop and my ipad. But when I connect directly to the router with a network cable, my connection is fine. So it is definitely a problem with the wifi signal itself.
What I have done so far:
(1) I checked all of the MAC addresses connected to my wifi. I identified my tivo box, laptop, and ipad. Nothing else.
(2) I used [I]wifi analyzer[I] on my android phone and selected an unused wifi channel (channel 8).
(3) I changed the username/password on my wifi signal. I also changed the password for my router's admin privileges.
(4) I restarted my router and computer.
None of this helped.
I am using a Netgear WGR614 wireless router.

My wireless seems to be fast for a good 30secs then bang takes good while to load the next page almost as if it's disconnecting and then reconnecting/scanning reconnecting. Why cant it stay connected. I have WAP PSK security here is my network setting please let me know if I should change any of them:(side not is there a way to fix this problem occuring so frequently it says on the wiki that it should only occur once in a whilce https:[url].....

I've just installed the ubuntu 9.10. I have one problem with it. I have a home net in configuration: Windows XP on a cable, Ubuntu on a cable and Windows on wifi. When I'm surfing on the net on Ubuntu, Wifi isn't work how it should. It's very slow and I don't know what to do with it. Windows XP on a cable is OK, it works good. What happen and how can I repair it?

I'm having an issue where a server in CA (1000/full) and in VA (100/full) have very lopsided data transfer.
CA -> VA with iperf shows ~20Mbps
VA -> CA with iperf shows ~93Mbps
If we change the CA server to 100/FULL, transfer speed is 93Mbps both ways.
Some tuning was done to TCP window scaling parameters, but it won't correct the issue, just improve the CA -> VA numbers to what is listed above. I will say, turning TCP window scaling OFF will lower the transfer speed both ways to < 20Mbps.
The only clue I have when looking at wireshark dumps is that the window scale going OUT would never go past 10240 (scale is 8, so 2^8 x 40bytes). In the opposite direction, the window size will go above 3MB (scaled).
It is not a bandwidth problem as iperf with UDP shows 93Mbps both ways. Local transfers (CA 1000/full to CA 100/full) show full speed both ways, so I feel it is strictly related to TCP window scaling.
RedHat 5 64-bit on both sides. Any ideas why it won't scale above 10240?

My computer takes a while to connect to my Linksys N router.
It used to connect in a snap of your finger automatically.
Now it does not.
Yes I have tried manual configuration, and double checking the password, ssid, protocols, and security type.
WPA2 personal is the security type.
There are maybe 4 different ways I know how to connect. The most annoying thing is when this box pops up saying to type in a password for the network connection.. and keeps popping up even when everything is right.
All I need is a reliable, easy, and automatic program to connect me to the internet, maybe even before I log into my system.
Linux Ubuntu 8.04 LTS Desktop Edition is my system. Brilliant system.

Like the title, that is my problem. I'm using cable modem with 3mbps. It is Linksys Docsis, wired networking. When I download a file using ubuntu 9.10, my latency time (ping time) sky rocketed to 2000ms average, while in XP none of this happens; I tried to download the same file from the same website. In ubuntu 9.10 my network setup will be, well... nothing. I'm using DHCP automatic detection. Same thing in XP.
I don't want to go back and forward using XP for the internet. Funny thing though, none of this happens while I first started ubuntu 9.10. I didn't configure anything with networking. It is the way it is from the beginning. The only thing I tried was ubuntuone. But that like months ago, and the problem I have with slow internet connection only appear this March.

A lot of people have the problem to find themselves with Lucid Lynx 10.04 and experience massive issues when connecting to wireless - me too. As a service, here some relevant links which promise relief:
[code]...
I tried all of them, and none reliably worked. Every solution which required re-association wtih the AP helped for some time, but nothing helped for long. First, don't let yourself fool by the disable IPv6 trap - while it is "enabled" it is acutally not used by Lucid! I have a clean install of Kubuntu 10.04 on an AMD64 Laptop with Broadcom STA driver: 03:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03) However I can reliably stabilize my connection for some time either by manually disabling WiFi with the hardware switch or disabling WiFi by software means and re-activating. This brings speed at par with Kubuntu 9.10 until some time. Can anybody confirm this behaviour?

I'm running 11.2 on a Dell Latitude D630. Everything has been great other than issues with Suspend and hibernate not working correctly. However after about a month of use browsing the web has really slowed down bad. It doesn't seem to matter if it's in Firefox or Chrome either. I am using a wireless connection that is getting the signal at 85-95%. Even though I still tried using a direct cat-5 connection to the router and it was still slow as well. I have the fastest broadband connection my cable offers and my windows boxes on the same network are still flying.

My WiFi can connect to internet without any problem, until I plug my ethernet cable ...then I lose internet.
So the question is : how do I configure my ip/dns and stuff to still have internet when I'm plugged by cable at the same time! it was working on windows ;-)

My ubuntu system has been running really well until this morning - software update prompt appeared on the screen, so I ran with it and let it do its thing. A while after this, my WiFi network connection started failing. I've tried rebooting and then it can take up to five minutes or more for the password (keychain) prompt to appear. Once I have typed in the password the network connection starts to work. Then cuts out. Works. Then fails again.

Wifi network operated perfectly with f13. Upgrading f13 to f14 did not show any problems except for networking. It seems that the wlan0-link is not ready. Consequently no network information about adresses can be obtained. Tried with network tools to activate wlan0. No reaction Tried to deactivate Networkmanager and bring network up with
service NetworkManager stop
ifconfig -a
Then
ifconfig wlan0 up
dhclient wlan0
No reaction on network. The NetworkManager icon disappears which is understandable.

I'm using wlan and I'm behind a NAT firewall. Downloading with BitTorrent can reach speeds of 1,5MB/s, but browsing is incredibly slow. Chromium/Firefox seems to hang forever on "connecting.." or "waiting for". Sometimes pressing the reload button will speed it up. I have two Ubuntu boxes and they are the same way.
I don't get it, if downloading is so fast, how can browsing be so slow. Yes I have disabled ipv6 in grub and in Firefox, don't know how to do it in Chromium. Have 64-bit Ubuntu. Cnet wlan card using rt61pci module.

I was wondering if there's any way for a laptop to be both simultaneously connected to a wireless network, while at the same time acting as an ad-hoc network with local access to serve as a wifi connection for my mobile device, which would be ssh-ing into the laptop and using local resources.

I know this has been covered before, and I have searched for two hours with no success. Problem: When trying to connect to public wifi in coffee shops and fast food restaurants, I can connect to the networks fine, but Firefox will not display the page that requires input of a code or terms agreement.
I remember months ago reading something about using the ifup command somehow as a work around, but there must be an easier way.

I have search the web quite a while about issues with the Intel Dual Band Wireless-AC 7260 Wi-Fi/Bluetooth card. It seems plenty of people have trouble (or at least have had trouble) with it. I do have a working connection, device seems recognized etc, but it works only at a very low/annoying speed.I'm running Wheezy backports and I have firmware-iwlwifi ver 0.43 installed (from Debian testing).
Below is some system output
Code: Select all$ uname -v
#1 SMP Debian 3.14.7-1~bpo70+1 (2014-06-21)
$ dmesg | grep iwlwifi
[ 1.784455] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X
[ 1.809630] iwlwifi 0000:03:00.0: firmware: direct-loading firmware iwlwifi-7260-9.ucode
[ 1.809713] iwlwifi 0000:03:00.0: loaded firmware version 23.214.9.0 op_mode iwlmvm
[code]...
I'm not sure why modinfo iwlwifi only lists firmware iwlwifi-7260-7.ucude while in dmesg you see iwlwifi-7260-9.ucude loads.

No improvement since I first reported this problem, I am hoping somebody can now advise.
Using openSUSE11.3 Linux 2.6.34.7-0.5-default i686 with kde 4.4.4 release 3.Problem is the wait of sometimes over 2 minutes before the wifi connection is available.Two questions:-
1. Why does it take so long? Longer by far than it to be with previous openSUSE releases. Much longer than with that other OS!!!2. How do I remove the wallet process. Not needed in present environment so I would like direct connection without having to open wallet. I didn't set this up, it just happened after I had upgraded to 11.3 and I need to know how to disable it to save time.

I recently installed the vt6656 wireless pci card that came with my zotac motherboard. I can associate with my ap and get an ip address successfully. When I disconnect my ethernet cable, however, my wireless interface stops responding (can't ping it). The box itself is in a place where I don't have a monitor connected to it so I cant see anything since my ssh session gets killed as soon as I disconnect the ethernet cable.
What would be the reason why the ehternet cable being unplugged, disconnects my wifi card as well? Does something get triggered? I did some testing with iptables, blocking the 8080 traffic to the wired interface, and noticed that the 8080 traffic also gets blocked to the wifi ip. I'm afraid that this never worked properly to begin with.

I am trying to run a cable from my wireless router over a 75ft cat6 cable to my bedroom. I don't get any connection on my end and I don't have any other ideas. I did setup a m0n0wall box just to try. I got the network led on my server to light up in my room but nothing more than that. Lastly, I tried adding a 5 port switch in my room and then connecting that to my server and nada.

I've been reading too much and understanding too little. What I have: Lucid laptop & desktop. Both have ethernet > hub > internet. What I want: connect them directly by the serial ports so the laptop can access the desktop's drives, and the desktop can be retired from the internet. I've got an old DB-25 null-modem, last used for multiplayer Doom. The laptop's dock has DB-9, so the connections is desktop > null-modem > Belkin DB-25 - DB-9 cable > laptop.
I had hoped this post would get me somewhere:[URL].. No such luck. When I ping 'grin.local', the connection is through the internet. If I disconnect the hub, i cannot ping.
Dunno if there's something more I should do to enable serial connection in Lucid, or if my null-modem is no longer good. I'm also rather curious how "grin.local" manages a connection through my ISP's system. These are DHCP. Shouldn't that have required the full numerical IP?
(It's nothing to do with the hub. Checked that by connecting a third box to the hub. My ISP only hands out two IP. I couldn't ping the third box.)

I have a desktop running Ubuntu 8.04. I installed 10.04 on my laptop. When I mount my desktop music folder on my laptop and transfer files, they now only go at 100-200 KB/s. When I had 9.10 installed, they transferred at 1-2 MB/s.
This is the command I use to mount the directory:
sshfs matt@169.254.6.233:/home/matt/Music/ /home/matt/Music/desktop/
Is there any way I can speed it up to get it back to max speed?
