Slow internet


I am having trouble with slow internet access. I have a Shuttle XPC currently running redhat fedora, but I had the same problem with Mandrake 9.1. This box also has Windows 2000 and also on the LAN is a Dell Dimension running WinXPpro. The LAN uses a Linksys router/firewall (NAT) and then connects to the internet via cable modem. The Windows systems are both getting about 540 kbps on numion.com. Using Linux it is about 10 times slower! I have tried Mozilla, Konqueror, and Opera....all the same results. The box picks up IP via the router's DHCP and it seems to have the right DNS entries and route shows the right gateway address. I don't think this is a DNS problem. Also, even trying to use the redhat update utility is unbearable slow, so I don't think it's just http (but I'm not completely sure of this). This seems to be some problem between Linux and my router, but I'm not sure of that either. I have played with various Linux distros for several years, but I don't use it full time and am not a Linux expert. Any help would be greatly appreciated.

I'm having just about the same exact issue. I've had some help from here as far as speeding linux itself up (and it has) but I get the same thing. no matter WHAT browser I've used, it just takes forever to surf the web.
i'm using a compaq armada e500 with the onboard intel 82559 nic (using the e100 module), and the Linksys router that only has two ports (wan/lan)
I'm not using DHCP, just static, with the correct DNS servers.
All other networking internally (rdesktop to other windows boxes, ftp'ing internally) go off without a hitch.
HOWEVER, just trying to go to a page like CNN.com or Google.com can take longer than Windows (and not just a little bit, either)
ANY assistance is GREATLY appreciated, as I've already learned there are some cool people here.

slow internet

Well, for what it's worth, I'm pretty sure now that this isn't a DNS problem. Using nslookup and dig utilities, the linux system appears to resolve names as fast as the Windows systems. Also, I tried timing an FTP download from my personal Web space and it was about the same for both OSes (maybe even a little faster under linux). So, at this point the problem seems to be limited to Web browsing (http). Anyone have a clue?

Answer found!

I solved this problem! From reading some other posts, I came to suspect my router (a Linksys BEFSR41). The Linksys had the latest firmware but I thought it was time to upgrade. I got a Netgear FVS318 and the difference is incredible. Now Web surfing from Linux is just as fast as Windows. I wish I knew exactly what the problem was between Linux and the Linksys router, but the problem is fixed. By the way, the Netgear is a much more robust router anyway, so I am pretty happy all around.

same slow connection problem

I'm using fedora at my university and getting the same problem you are describing. Does anyone know of a solution that doesn't involve changing the router/hub?

thanks

I've got the same, or at least similar, problem. I'm using Fedora Core 2 test1 and a Linksys BEFSR41. the confusing thing is that i cannot access the router through the web interface (at 192.168.1.1), yet i can successfully ping the router at that address. i can access the internet, but it seems spotty. most of the time it is fast and normal. however, it seems to hang randomly when first accessing a site.

for example, about 1 in 3 times I try google.com it will wait for about 15 seconds before connecting. it happens with seemingly every site i go to.

also, i cannot ping some sites like ibm.com, yet i can connect to them with a web browser. this problem did not occur when i was using Fedora Core 1

hopefully, someone can be a buddy, as i would not like to experiment with the previous poster's solution of buying a new router.

thanks in advance

I had the same problem with Windows 98. Reformatting the hard drive solved it

Lightbulb Try this

Hi everyone!!!

Try to download the same information or better, download a file that´s be upper than 100Megabytes, trough the text-mode browser clients (like lynx, links, wget)

If the speed of the internet is good, that you´re need some RAM or another VGA Card.

before u dump your router/hub...you could try a few tweaks to TCP/IP networking.

1. To enable your box to handle more connections try setting
tcp_fin_timeout=30
tcp_keepalive_time=1800
tcp_window_scaling=0
tcp_sack=0
tcp_timestamps=0

2. For total, read, write to tcp buffer-space change the settings on the following ( depending on how much RAM u have)
tcp_mem, tcp_wmem, tcp_rmem

3. receive & send buffer size change settings on
rmem_max, rmem_default, wmem_max, wmem_default

4. for tcp time wait bucket pool size u can tweak
tcp_max_tw_buckets

5. look into changing default settings on ipfrag threshold and optmem_max ( for ancillary buffer size)

6. I have these TOS set for http in my iptables bash script

iptables -A PREROUTING -t mangle -p tcp --sport http -j TOS --set-tos Maximize-Throughput

iptables -A OUTPUT -t mangle -p tcp --dport http -j TOS --set-tos Maximize-Throughput


I dont know if these will help speed things up for you..and depending on what ur settings are you could already be on an optimum setting....but its worth a shot

hi,

i had similar problems. Recently I solved it for my SuSE9-Box by diasabling IPV6.
Now I have the same problem with mandrake 10 again, but I can't simply disable IPV6 anymore.

I'm working on it. Stay tuned ;o)

P.S: I'm wondering why IPv6 sould be the problem?

Solved!

erf I don't understand why, but now it works. (I feel a little bit "windowish")
1.) I recognized that ACPI wasn't working properly because of a strage BIOS setup ==> set kernel parameter acpi=force.

2.) I reinstalled the network-interface with hotplugging enabled

result: ifconfig shows eth0 without ipv6-adress ===> network is fast again.

Erf, I really don't understand why ipv6 now is away? especially when i tried to set NETWORKING_IPV6=no I couldn't remove it.

Ok now everything works -- so i don't care -- till the next time ;o)
