    if you are experiencing a slowdown in the web interface, would you reply to this post stating your internet connection type, firmware version and model version.
    i will need a volunteer located in the UK with some spare time, who's router is exhibiting this odd behaviour to help me test this as i don't have any evidence that a problem exists. i don't have the issue, nor have i ever seen it. without a helper i won't be fixing it; i won't be looking into it before i have a volunteer either as i have no base to start from. thanks

    Hi Thibor,

    I'm not from UK but I've experienced slow web interface response since I flashed my WRT54GS V4 EU to yours latest Thibor14 - especially when some P2P stuff is running. I have 1024/256 ADSL line, 54GS is connected via static ip to ADSL gateway in bridged mode.

    I've flashed back to Thibor13d (even to Tofu13c for test and is very fast too) and web interface is working normal (without any delays).

    Besides your firmware really rocks!! Thanks for your effort.

    Just one curious question: is your current codebase 4.70.8(GSv3) faster than 1.05.6 (GSv4)??

    Thanks :thumb:

    i'm sorry damko, but i'm not answering questions in this thread. i'm trying to gather information. i've noted your model and version though

    Internet: Comcast Cable 4Mbps Down 384kbps Up

    Firmware Version: v14, (At the very least 13d seemed to have this issue as well)

    Router Version: WRT54GS v4

    This isn't so much as a web interface issue as it is a a web browsing issue. I wouldn't know that for certain as I don't spend all that much time in the routers web interface past the initial few minutes spent configuring it. I wouldn't define it as all that severe either, but it is a delay when loading webpages. As I stated in the other thread it is most noticable for me when loading any webpage that isn't cached (regardless of the site), as it'll hang on Waiting on www.xxxxxxxx.com.... in Mozilla for rougly 1-6 seconds longer than it does normally before it all the sudden loads in one quick spurt. IE has the same issue.

    This issue appears to be prompted or at least made much more noticable when running a torrent or two (in my case, Utorrent) as when all torrent programs are shut off web browsing seems to respond immediately.

    Hope this helps, and thanks a bunch Thibor for all of your hard work.

    kekelala, that's not what i am talking about, please restrict your posts to the subject. you can try and use QoS, that may help.

    Hi Thibor
    Technical Data :)
    WRT54G v2.2 + HyperWRT + Thibor 14
    ISP IcpNET Cable Modem Motorola Surfboard 5100
    Connection 2048/256 kbps

    I expierienced this problem testing various scripts. When you have launched P2P client (eDonkey (use 45 connections), torrent (use 60 connections) no matter what) after few minutes web browsing, router GUI and other services are slowed down to speed < 1 kB/s. Only reboot helps to time when you launch p2p again.

    I want to be a volunteer but i dont live in UK :(

    Got a WRT54GS v. 1 BEFCMU10 v. 3 Comcast 6mb/s down 384kb/s up. Running Thibor 14 using Firefox I had problems with pages being slow was not the router though. It was the firefox Fast Back/Foward feature. My memory usage for Firefox was high. It then slowed everything down. Fixed everything works fine. Still haven't had to reboot my router. Just thought since it was a web interface problem maybe you should include your browser too.
    hope this helps.

    Note: this is not a problem with firefox just a feature.
    Fast Back/Forward
    Firefox 1.5 has a new fast back/forward feature (bfcache) that vastly reduces the amount of time taken to display pages when the back/forward buttons are used. This adds to memory usage.

    more info:

    Everything is working fine for me thanks Thibor :)

    glad to hear it. something has just come to my attention. with any of you that are having web interface slowdowns, would you also state if you have had dd-wrt loaded in the past?

    Hi Thibor,

    I am having this issue. Web browsing is extremely slow. All downloads are fine, online gaming is fine. Only web browsing is very slow to the point that it times out all the time and the browser I'm using makes absolutely no difference. I have a WRT54G v3 and I did flash it with dd-wrt previously and went back to the original linksys firmware because that particular firmware would drop the dhcp lease all the time. Since I have gone back to the original linksys v4.3 the browsing has been terrible. I had suspected that flashing that firmware may have caused this problem, but wasn't 100% sure. Now that I've come across this post I'm starting to believe that maybe it really is. Sorry I'm not in the UK or I would give you some time for testing.

    Thibor Super Moderator Staff Member Member

    i'm not saying for a second that dd-wrt is or was the cause, it's just an avenue of thought i'm considering, that's all.
  12. GhaladReam

    GhaladReam Network Guru Member

    I'm not having the issue you're talking about, but I DID used to have DD-WRT. However after flashing to HyperWRT+Thibor I fully cleared the NVRAM. If you used to have an old FW, you need to clear out its old settings otherwise they could conflict.

    there is also a potential for "FasterFox" to be an issue, as well as not applying the EvID4226 patch for SP2.
  14. YogSothoth70

    YogSothoth70 Network Guru Member

    I am not having the issue. Quite the contrary, actually. With 14, browsing and using the web interface seem even faster. As far as FasterFox, I'm using the latest version of that.

    The WRT54GS I use as the main router is a version 1.1.

    ive found a factor in what makes torrents bad, and i dont know if this is with torrents in general or just utorrent.
    loading small and medium torrents works fine and my speeds often reach the maximum my cablemodem goes, and web browsing and everything else works fine.. but last night i joined a very large (15,000 peers) torrent and everything went to hell. keep in mind that i have it set to connect to only 120 total.
    -took 10-15 minutes before i had the maximum connections i had on that torrent, which was only about 20 peers for some reason?
    -maximum speed was about 30 KB/s
    -web pages werent just slow, they WOULD NOT LOAD. i would type a url and it would just stay blank, there was no attempt at even loading the page as if there was 0 connections available. same for both firefox and ie.

    so is utorrent making a lot more connections than it says it is? is dht doing it? whats grinding the entire connection to a halt?

    DHT in itself causes problems. try disabling it and see if it helps

    evil-doer Network Guru Member

    so will dht and kad in emule always not work with this router? can you tell me WHY exactly it has problems? and why other routers can handle it? is it the cpu? memory? wheres the problem and can it be fixed through software? because right now im ready to throw in the towel and go back to xp ics as my router, and leave the wrt as an access point only. every day its the same thing. my network speeds drop to unusable levels. and as ive writen many times before, ive followed every advice and tried every trick. i cant even stream movies to my xbox from another computer on my network without it hicuping. it seems like such a waste of money me buying this router and i had such great hopes for it, being linux based and programmable.
    so please, give me a straight answer and tell me where the problem lies and if its fixable. thank you.

    evil-doer Network Guru Member

    ok i didnt wait long, i was absolutely fed up with this garbage and dropped an xp ics box where the router is. oh... my... god... i had forgotten what regular internet is supposed to be like. i started up TONS of torrents, maxed out the connections, loaded up emule, did many searches, then browsed the web. id say it was.. oh.. 100x faster than usual. everything was instant. no slowdown whatsoever. i literally forgot how fast my system was because i was so used to that crap. so my questions still stand. why the hell is this linksys so god damn slow? why do routers that cost be a couple of bucks run p2p apps better?
    oh well. i needed an access point anyways.

    Something is wrong with your router, either with the hardware itself or the configuration.

    I had a WRT54GS die a while back, and also resorted to ICS for a few days. In every way, it was a little slower than the dedicated router. Not by a huge degree, but noticeable.

    My Linksys WRT54GS running HyperWRT Thibor is just plain fast, stable, and set-it-and-forget-it. It's so good I've become a bit of an evangelist about it, when a friend ever says something about "my Internet being slow" we go get a WRT54GS v4 at CompUSA, load it up with HyperWRT Thibor, and then happiness occurs. I've done this three times now.

    I end up using t-mobile hotspots, wireless networks at friends' homes, wireless networks at client offices, and my home network with a WRT54GS running Thibor absolutely provides as good throughput as the other connections, and often better throughput.

    how would i diagnose if theres something wrong? there must be some diagnostics i can check? and how come ive read countless other people talking about problems with dht and kad? ive been reading every bit of info i can since i bought my wrt54gs and tried everything. i reset the ram, reset the settings, tried every tweak, tried all the tweaks on the torrent software as well. what can i do?? what part of my router could possibly be broken? theres gotta be some way of testing where this problem i have lies.

    I definitely could not run trackerless BitTorrent transfers for any extended periods of time with the stock Linksys firmware, but I'm guessing it's the number of connections or timeouts in HyperWRT that is the change that makes it work.

    Here's what I've done with the WRT54GS routers I've helped friends set up:

    1. Get a Linksys WRT54GS v4 at the local CompUSA. They seem to have plenty in Chicago.

    2. Clear NVRAM, restore factory defaults.

    3. Firmware upgrade to HyperWRT Thibor GSv4.

    It sounds like this version confuses everyone. It's for upgrading a stock WRT54GS v4 directly to Thibor without requiring any intermediate firmware. If he stops releasing that version, it sounds like you'll need to flash it first with DD-WRT Mini before you'll be able to load HyperWRT Thibor GS.

    Maybe he needs a better explanation in the readme on his site? I have not seen Thibor explicitly say this, but maybe he should post something along the lines of:
    3. Clear NVRAM, restore factory defaults again after it's running HyperWRT Thibor GS.

    4. Set up the Firewall. Block Portscans. Block Anonymous Internet requests. Filter Multicast. Do not filter Internet NAT Redirection. Filter IDENT. Enable Passthrough for all VPN types.

    5. Set up UPnP: Enable UPnP, Disable "Clear port forwards at startup", Enable "Send presentation URL".

    6. Set up QoS. Upstream bandwidth "Manual" based on Speakeasy Speed Test. Priority Highest for DNS and VOIP applications and DNS. Priority High for HTTP/HTTPS. Priority Low for PTP. Prioritize ACK and ICMP.

    If I don't do this step, they still seem ok with P2P, but always complain if and when they try VOIP applications so now I just do it. I do no special P2P configuration within the P2P application, I just let it use all the bandwidth it wants and let Thibor just prioritize it behind VOIP and web browsing.

    7. Set up Conntrack settings: 600 seconds for Established State Timeout. 4096 for Max Connections.

    8. Set up a Startup Script.

    echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
    echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses
    9. Set up static DHCP addresses for all of their systems.

    10. Pretty much leave everything else alone, including leaving Dnsmasq running.

    11. Backup the configuration so that they have a good baseline in case they play with it later and make things worse.

    12. There is much rejoicing.

    If this doesn't produce acceptable results for you, then I would tend to think there's something's wrong with your router, or outside of the router, and not the configuration of the router. This has worked in a number of different homes, including with simultaneous P2P (typically Azureus), VOIP (Skype or Vonage), and web browsing. For most simultaneous P2P and VOIP, they can't tell the difference when web browsing. They can tell a difference when P2P is running hard with tons of torrents, especially with trackerless DHT torrents, but it's very minor, more of a genuinely hard-to-perceive lag from the click on a link until the page loads. But it still easily passes the "feels snappy" test with DHT torrents running! :)

    Heh heh, it's the ROUTER's fault and not the P2P software? People always so quick to point finger at <$100 router instead of >$2,000 PC. Seems wrong way around.

    evil-doer Network Guru Member

    HEH HEH. hello? have you read anything ive said. and isnt it you thats jumped in with this stupid idiotic remark last time?

    IT WORKS FINE ON ROUTERS THAT HAVE COST ME 0 DOLLARS AND 10 DOLLARS. im comparing it to those cheapass routers, not to my pc solely. jesus.

    and yes dvaskelis, ive done everything on that list.

    anyone have any help on how i would diagnose the problem?

    Im not sure if you have done this sence it was not mentioned but are you running xp with sp2? and if the case have you tried adjusting xp half open ports from 10 to a higher number like 100 or 500 or even 16777214 with EvID4226? Then tweaking the halfopen settings in µTorrent? I ask this because this is the one and only thing that I do and If i dont I experience slow or not loading webpages even slow loading the router webpages when behind this router. If I do adjust these things It runs as smooth as butter infact I dont have to adjust a thing in Thibors software after or add startup scripts and this seems to work fine in my situation. Also on a side note you might wanna try limiting your global upload speed and make sure you dont max that out while downloading as on alot of asymmetrical connections it can sometimes send your connection into very high latency's. I can understand your frustrations but remember you do have alot of nice people trying to give you a hand(try not to loose your cool).
    If you have some free time to play around instead of xp ics try this great free dedicated router software package. http://m0n0.ch/wall/
    it does not run under windows, takes very little space and has a great layout.

    Slow down in interface and surfing web - not games


    ntl cable 1024/128 kbps
    WRT54G v2.2 thibor13d and 14 have web interface/surfing problem

    I am from the UK and have a WRT54G which i upgraded to hyperwrt 2.1b1 then to thibor 14. I was amazed at the options etc and went setting up the QOS in order to play games and use P2P at the same time. I was playing and all was fine for a while then sometimes randomly high pings. I then tried accessing web pages and they were sometimes slow but not always. Stopped bearshare and the probelem disappeared. Started bearshare again and almost immediately problems re appeared. I have given highest priority to http/dns and low to p2p. ticked the box for games. tried re flashing/clearing nvram/resetting and now i have gone back to thibor13d which doesnt IMO seem any/much better. I have tried this with 2 different wireless adaptors in my pc and the laptop i have has same problem whether wired or not.

    Hope this helps you, and perhaps you have any ideas for me?

    upgraded from stock firmware --> Thibor 14

    did not use any dd-wrt previously.

    first day, web interface was slow

    however, 2nd and third day, its totally fine.

    Hi Thibor,

    I'm experiencing the web slowdown too. Got a cable internet connection, WRT54GSv3 running Firmware Version : v4.70.8, Hyperwrt 2.1b1 + Thibor14. The only other firmware I've had on this has been stock.

    Got all of dvaskelis's suggestions implemented except for the static DHCP (although I had tried that previously) but hopefully I'll be able to do that tonight.

    I live in the U.S. but as I've paid for 2 years worth of the parental control subscription that I bought this router for in the first place, I'm willing to get up at some obscene hour in the night (during the weekend, hopefully) to work with you.

    Please let me know if I can help, thanks.
