Ubuntu Networking :: Speed Up The LinksysWRT54G Router??
Jan 13, 2011
I was about to invest in a new, current-tech router in an effort to speed up my internet performance. My on-line research uncovered the fact the the LinksysWRT54G router is easily modified to expand and increase its performance. That's because it's firmware is Linux based and therefore open-source.A google search turns up a number of sites with instructions. I've been reading this one: http://www.wi-fiplanet.com/tutorials...T54G-Story.htm. I'd like to hear your experience if you have ventured through this or found some other "easy" way to increase the Linksys router performance.

PC running Ubuntu 10.04LTS, with a Virgin media modem NTL250 with a Buffalo Airstation Turbo G wireless router running Tomato Firmware v1.27.1798.The router is is used by a Internet radio, a wii (both full time) and a nokia N86 mobile and a PSP (used occasionally). The PC is connected by a network cable to the router.Now, when the modem is plugged directly into PC i get 6 to 8 Mbs download speed. When I go modem to router to pc the speed drops down to 512 to 824Kbps. Speeds were obtained off of broadband.co.uk speed tester.

Because of the configuration of my house, I need two routers.I have a DLink ADSL router as my main router and the Belkin N1 as my repeater.I have set up the IP address in the Belkin to be 10.1.1.10 - my DLink is 10.1.1.1. I have disable the dhcp in the Belkin and set the DNS as ISP provided. [URL]..I have set the channel to 11 and in the Ubuntu Network Manger I have set the IPV4 to Link Local Only. I can see the Belkin and connect with my PC.but it will not take me through to the internet.

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

These r IP provided by my ISP that i've put on Fedora 8:
WAN IP:xxx.xxx.xxx.17 (eth0)
Subnet:255.255.255.252
Gateway:xxx.xxx.xxx.18
Valid static(public) IP set of 2:
IP:xxx.xxx.xxx.147 & 148 (eth1, eth2)
Subnet:255.255.255.240
i want to run xxx.xxx.xxx.147 as a web server & xxx.xxx.xxx.148 as a ftp server. but I'm able to ping only xxx.xxx.xxx.17(WAN IP) from outside world. Can any1 tell me that how can i bring my 147 & 148 IP online without router.

I've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.
Here's what I did:
The newgateway is setup for class C, 192.168.0.0
This configuration works, but sometimes it doesn't and I haven't figured out why yet.
At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.
Other times, it seems nothing can talk with anyone, and I am not sure why.
I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.

My son lost his USB Wireless stick for his Computer. I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.

I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.

Ubuntu 64bit. The sound system works and plays noises correctly when I test the speakers in sound preferances. The internet BBCi player(Radio) plays sound correctly. Banshee & Rhythmbox try to play music files at double, or more, speed with no sound output. Spotify Linux version also tries to playback at double speed with no sound output. Media Player attempts to play music files at high speed. Media player plays the Video and audio tracks at high speed. VLC Will play the video at normal speed but with no audio.

I am thinking of moving the router behind a server and connecting the server directly to the internet via a modem. Are there any security issues related to doing this? or other things I should be aware of. Iptables are implemented on the server blocking access on unused ports.

I have a 18Mg download speed internet connection and surfing the web is supper fast, streaming video is decent, etc. when I go to download a file 100 mg or so really anything my download speed will clime to about 1.3mg and then start dropping and level off at about 32 kb or lower. if I pause and restart the download it will jump back up again for a while and then come back down. if i constantly pause and restart the file will download in roughly the same amount of time as if the connection was working properly.

I have hesitated posting this because there are a number of threads on the Asus USB N-13.First let me point out that I am using this device.It worked out of the box in Ubuntu 10.10 after several reinstalls using the native Ubuntu driver.However my speed is stuck at 54Mb/s.When tested on a Win7 machine, the connection speed is much closer to 300Mb/s.In wading through the other threads, I am unable to find anyone who has this adaptor running at N speed in Ubuntu 10.10.I have downloaded the latest ASUS driver for LInux but have not installed it as my previous attempts at doing this failed miserably and each time necessitating an OS reinstall.I am an experienced Windows user but a rank newbie when it comes to Ubuntu. The following is the result of iwconfig:chad@linuxbox:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

dualboot win7 and ubuntu 10.10 x64.All was fine. Suddenly I noticed that download speed on ubuntu is 100-500Kb/s, while it has to be 100Mbps. Same resources download 9Mb/s on dualboot win, so it is not hardware/isp problem. This problem occurs when connecting by eth cable. The connection is over ppp0 vpn tunnel.The ping is very slow - around 300ms even to my ISP.The only soft I was installing recently is tor/vidalia/privoxy,but I removed them all.I also noticed that avahi-daemon is running, can it be causing the delays?

I can only connect at 54Mb/s "g" speed. I am assuming I need to compile a newer driver - unfortunately I have become quite confused with the plethora of threads on the subject! And most of them dealing with older ubuntu versions.

When using launchpad and the ubuntu daily build website it is very slow. I get 1.2mb/s normally and the speed drops quickly to 0kb/s This is the case from any version of ubuntu that is installed on my laptop.In windows it is no problem, equally there is no problem from a live cd or an install on my external hard disk. Is canonical blacklisting/slow listing my ip?
I am behind a university network but am sure this problem occurs at home .I did a clean install and had no problem until about an hour ago. When I tried to re download a project using bzr my speed instantly ropped.I had downloaded it fine a couple of hours ago. I hope that someone can shine some light on this, its very hard to work on projects if I can't download them.

Last week my ping was 45 this week its 80. I've checked it on three different computers, and reset my router. I called verizon (my subpar isp) they run a few test, say every things fine. I recheck my ping, its back to 45 but only last 5 mins after they check it, then it goes back to 80. I'm always having problems with them, but every time I call them the problems "just so happen" to go away while their helping me.
Anyway, my question is... Is there anyway for me to increase my ping/speed without upgrading my internet? I have 3.5 upload, .75 upload, and a Westell model 327w. I know this is a general question and not really linux related but I thought I would try this forum first since its always so helpful. I have googled this subject but I only find windows related stuff that pertains only to the programs running on the machine. They suggest things like "dont download when you want high ping" and "temporarily turn off seeding for your torrents" It is most important in windows for me though, I like to play games and a difference of 50 and 110 ping does make a difference. Of course, everything seems slower, like streaming movies and stuff.

I am having problems with download speeds in Ubuntu 9.10. Downloads start at a healthy speed and then drop to almost zero. This affects apt-get install, Pan newsreader etc. With apt-get install if I terminate the download (with [Ctl][C]) and restart it I get another burst at high speed then again back to almost nothing. It makes updates a nightmare. With Pan newsreader I get high speed for most files but when downloading some of the larger files the speed drops right back to almost nothing after a while. I am on wired ethernet (no wireless). Typically I will get about 1.1MB before the speed drops - although I think it may be a function of time rather than data. I am talking to my ISP via a Netgear FWAG114 router and a NetComm NB5 ADSL modem operating in bridge mode. Although a number of users appear to have experienced very similar symptoms here I haven't found an answer that works.

I was having terribly slow internet speed with my wireless setup. I followed someone's advice and now my internet speed is flying. However, now I lose connection a lot - almost once every few minutes. Is there any reason for the changes listed below to make me lose connection so easily?
SETUP:
Ubuntu 910 - 64Bit
Wireless Router: WRT160N
Wireless Card: PCI Asus PCE N13
Changes that improved speed, but killed stability:
Radio Band frequency should be 20 MHZ,
standard channel change to 11
advanced wireless settings should be Beacon Interval 2306
Rts thres = 2307
Disable the Security easy setup*option.
Uncheck the Block Anonymous Internet Requests & reduce the MTU size to* 1400

When the summer-holidays are a fact and it's time for some fun I will be upgrading my home network with a diskstation of some kind, and since all models I currently looks at supports 10/100/1000 M/Bit networking it got me thinking.
My desktop also supports 10/100/1000 M/Bit networking and since I already uses a 10/100 M/Bit switch between my desktop and (file)server, it would be very easy to buy a new switch that also supports 1000 M/Bit networking and then connect the diskstation to that switch as well. But the router the new switch will be connected to is only running 10/100 M/Bit so the question is, at what speed will the new switch be running?

I recently got karoo broadband installed, the speed is normally 8mbps but the longer I am connected to my router the slower it gets, I have to disconnect and reconnect to the router to get back to full speed, is this due to a bad wireless driver or do I need new drivers or a better router.
