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 use ubuntu 10.10 in my AMD 64x2 4000+ processor. I had downloaded half portion of a certain torrent file using ktorrent(in gnome). Now i have installed utorrent using wine. Is there any way i can transfer the half downloaded torrent to utorrent and continue downloading the rest part in utorrent.
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 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'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?
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.
I have two Ubuntus installed. A 10.04 and a 9.04. In 9.04 if I watch a video in Firefox, it works very smoothly and nicely. Using the "top" command, totem-plugin-vi is using the most cpu time at about 16%, and xorg is using about 5%. But in 10.04, totem is using 72% and xorg is using 26%, and it looks really choppy. I think watching DVDs is the same way. I checked "Hardware Drivers" in the System->Administration menu (in 10.04) and it said "No proprietary drivers are in use on this system." I'm guessing maybe I'm using different video drivers on each system, but I don't even know how to check. and here is an excerpt from lspci:
The local files copy speed from one disk to another is satisfyingly 60+MB/s, but this cause problem to other application, windows gray out, firefox freez, basically i have to wait for the copy to end to return to the computer.
I have a fast server running Debian 5 (I tried to upgrade and everything broke.
So I'll stay with Lenny): Core 2 Duo 4Gb RAM RAID 0 100mbit
When I use the -X command and try and run applications to my desktop, it is VERY slow. Firefox takes 20 seconds+ just for a right-click menu to appear. It is completely unusable because of this speed. And this is after a clean install of Debian 5.
I've tried on multiple clients (Windows and OS X) and it is always slow! Even though both computers and connections are fast. My home connection is 100mbit too....
So the problem is not bandwidth or resources, the problem must be with the server/software? Any ideas why tunneling X11 applications are so slow? Is there an alternative X11 software I could use on the server?
1 thread in FTP to this server gives 10MB/s (100mbit). So X11 should be fast? And btw, I'm tunneling through SSH.
I have a fileserver running 10.04 server 64bit and samba. I connect it to my desktop which is 10.04 desktop 64bit.I have the server mounted on my desktop in fstab as://10.0.0.2/share /media/share cifs guest, uid= 1000.Up until 30 June 2010 it was all fine. Now when I write the server it is very slow e.g. 2Mbps though when I read I get >100Mbps so I think my network is still ok. If i use nautilus smb://10.0.0.2/share I can write at >100Mbps and also read at >100Mbps...So any ideas why the write speed via the fstab mount samba has started to go really slowly in the last couple of days?
I have Ubuntu and Win 7 on my desktop machine. I use utorrent and deluge for torrent clients because i upload on lot of trackers. I want to import the settings and paths for the torrent to some linux client. I have 700+ torrent now and it would be real pain to add them one by one in linux. Is there any way to do that?
When I'm trying to login to the ftp server with appropriate username and password its taking almost 10-15 seconds to authenticate making the login process slow, even when I'm uploading files its again hanging for 10-15 seconds before completing the job successfully. Its not like its happening every time, but 7 times out of 10. Any idea how can make the authentication fast?
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.
I've recently moved my media center pc from windows 7 to Ubuntu, now while on windows 7. I used the machine with XBMC and utorrent with upnp enabled on my router (Netgear WNR2000 v1) and also in the utorrent client for the port mapping. I was also able to connect to the machine from work via remote desktop (via Windows RDP, real/ultra vnc) using either a windows machine or via ubuntu that I have installed on a laptop (externally to my network). Utorrent also was able to talk to my router and ask for the ports it needed via uPnp or even by setting the port forwarding manually.
Since upgrading ( ) to Ubuntu from windows 7 on my mediacenter pc I've not been able to connect via RDP / VNC using port forwarding from the outside world although I added ports 5900 and (i beleive) 3389 to the port forwarding section in my router and pointing it to the static ip on my mediacenter. I'm also not able to get the ports to forward for deluge / vuze at all, if i manaually set port forwarding up then nothing happens and deluge says it has no incoming connections and it also doesn't talk to my router to ask for ports via upnp.
The same also holds true for the linux version of sopcast which will not connect to any streams. I can also replicate the same issue on a laptop that I use with ubuntu installed. If I watch my upnp page on my router config then I can see that my windows clients (Brother & Mom's macine) both talk to the router and ask it for ports so I assume that the router is working as it should be but obviously the fault happens when my ubuntu )10.04.1) clients ask for any kind of ports. By default is there any kind of firewall installed on ubuntu or anything I need to do to allow it to ask for upnp connections?
I bought a new Laptop 2 week ago. It works well, but internet connection ist very slow. I use cable internet speed 25Mbit/s, normal with my old Laptop (Window xp) I can DL with speeds ca.1 Mbit/s but with this new ca. 15 kbit/s (same file). too much different!!! If anyone know, how to troubleshoot this problem, please tell me. And i get a advice that i should crate a new connection using the "workgroup" model instead. I've tried to do but failed. Who knows "how to" please explain it for me.
This is sorta a strange problem as it also happened in Windows Vista as well, one of the reasons I tried out Linux was to fix this problem (then fell in love with it and didn't go back).
Anyway, problem is that when ever I start downloading a torrent, no matter what speed the file is downloading at - fast or slow, as soon as I open a browser and then load a website it's like my internet connection has died. "Chrome was unable to find the website" "Firefox could not load this site" ect ect.
The torrents will still keep downloading/uploading, instant messages programs still work, but websites will not load.
My wireless connection drops after a while when downloading torrents. I have to reconnect manually. Current configuration is Macbook Pro 5.5 with Broadcom card and Lucid. I've tried with Transmission and KTorrent. It's not a network problem as my Win laptop works smoothly and with higher transfers rates (i.e. 1MB/s in Win vs. 300KB/s at most in Ubuntu).
Running Fedora 13 and have it working great acting as my firewall/router/samba server etc. The problem is the connection is shared by a fair number of us and the ISP is getting annoyed with the amount of torrent traffic. One of us has access to a wireless network and we'd like to figure out how to route some of the traffic through that without having to disconnect from the current network. I put a wireless card in the fedora box and can connect to the wireless but then it messes up the current network and pretty much nothing works.
At the least if I could run a torrent client (e.g. ktorrent or whatever) on the Linux box and have it download through the wireless card on tcp port XXXXX I would be happy. The torrent client and those tcp/udp ports can be dedicated to that wireless card, the rest of the network doesn't need to get involved if that makes things simpler. Not looking for a step by step tutorial, just an explanation of what needs to be done and a shove in the right direction. My experience is limited to single WAN connections up to this point.
I have installed Fedora 11 and Fedora 8 on two differnt machines and I am doing an rdesktop to connect to a Windows 2003 server. The connectiviy is pretty fast when I try and connect the same from fedora 8 machine but it very slow when I try and connect it from fedora 11 system. I have tried using TS client but even then it is pretty slow. I have also tried using an Nvidia 8400 graphic card and Nvidia 9600 on Fedora11 OS.
I have also tried using Fedora12 OS as well. Is there any thing specific I can check on Fedora11? Or do I need to do some thing on my windows 2003 machine?
I've been troubleshooting this problem for several hours now and I'm out of ideas. My internet connection is fine in Windows 7 but an older computer I resurrected (AMD Athlon 1.7 GHz, 512 MB RAM, Fedora 14 Security Lab Spin) is having the stop-and-go's with its internet connection. It will work for very briefly, then it gets extremely slow, where any page I try to navigate to in Firefox 3.6 takes forever to load.I have a DSL connection and my DSL modem is connected to a Linksys WRT54G2 router. I set up a static IP in Windows but don't know how to do this yet in Fedora 14, and I need to get my internet connection working so I can troubleshoot further, but with it being so slow, I'm having to use Windows to search for problems and then switch over to the Fedora box via KVM (IOGEAR), which I also just started using. I don't think that would be related, but who knows.
When i try to copy files from my samba server (Ubuntu 9.10) to my windows seven media center, the speed is extremely slow. So slow that is better to download 100mb file from the internet, than from my lan. And on my lan, every card and switch is at 1000 mbps speeds on cat5 cables. And from XP or other linux machine
I am looking to use an old laptop as a remote keyboard and monitor for a more powerful desktop computer. I do not want the desktop running when I am not using the laptop. I was thinking that a WOL script somewhere in the very beginning of the boot process would be the first step. I want to connect to a windows desktop and they need as much time as posssible to boot.I have 2 questions. What is the best way to send the WOL packet? Can GRUB possibly do it before booting? Second what is the slimmest distro I can use that will work as smoothly as possible?I tried to search but I am was not able to sort through all the different options without getting confused. One more thing. Can I set up the remote desktop so that when linux finishes booting it is already logged in and I am looking at the regular windows desktop? Maybe some sort of batch file on the windows pc to tell linux when it is ready for the connection. I am sure linux will win the race. After windows is ready the linux pc will initiate the rd connection. The question is how do I go about that?
I have an Acer One netbook,I tried the Moblin and Meego distribution and i liked some parts of the user interface very much,especially the fact that every window that you open comes out well maximized and easy to read on the small screen of the netbook .But I didn't like Moblin/MeeGo because they are too "rigid", difficult to customize if you don't like the default choices. I prefer something like Debian much more.I would like to find a nice, light and fast window manager for Debian that would give me some of the advantages of MeeGo/Moblin,especially the fact of maximize by default every windows that I open..
It can be summed up by saying the internet works fine some moments then becomes so laggy a few minutes later it is completely unusable. This is what has happened so far. First I went to scottrade trading platform, it takes real-time quotes of stocks and graphs them, allows you to see account information. It was working amazing for about 20 seconds, then out of nowhere the internet just stops working on it completely and wont come back. Then I tried WCIII. The patch would not download at all. I couldn't even manually get it. Then 3 minutes later I try it again and it starts making progress.
Ubuntu update files are downloading the slowest I have ever seen before. I went to ....., the videos download really fast for a few seconds then they just stop. No progress at all for at least a minute or so and then they crawl back to making progress. Web pages I visit work fine one moment, I go back to the exact same page a minute later and it doesnt work at all, takes a few minutes just to load.
I use basic ssh and scp on a regular basis and sometimes for file transfer... certainly over public networks. However, often I want to transfer large (several GB) files from one place on my LAN to another.
I've read that FTP is the fastest, and when I'm transfering many GB, fast matters. Of course I know it's not secure, but I don't need security on my home wired LAN. What I do need many times is preservation of date and time of each file when uploading. Filezilla does that and I use it, but sometimes I need a CLI solution. I have use ncFTP and been happy with it until I realized it doesn't preserve date and time on uploads (probably not on downloads either, haven't looked).
Is there a CLI FTP solution out there that will preserve file date and time information on file transfers (including uploads)?
At home we have a small home network, but it is very slow. I believe it is, because some computers are placed in a workgroup, called WORKGROUP and others are placed in a domain called TUE. The domain is because many of the laptops at our house also have to work on our university, and I can't simply put them in a workgroup.
The reason why I believe it is slow because of this, is because file sharing between the computers in the workgroup goes with 5 MB/s. File sharing between a domain computer and a workgroup computer goes as fast as 160 KB/s. This is the upload speed of our internet here. How to make the connection with the domain computers the same speed as the workgroup computers? I can not simply put the domain computers out of their domain and in the workgroup (as explained before)
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.
