Which Firmware is the fastest?

    Hi there,
    I own a WRT54G v2.0 and a 6016/576kbps internet connection. With direct connection to my dsl-modem i get ~710KB/s download speed and ~64KB/s upload speed.
    Behind the WRT54G I "only" get ~650KB/s download. If I have many connections (f.e I tried downloading the KNOPPIX DVD-Image via bittorrent) I hardly get over 250KB/s. It seems, that the router reaches its limits there, as an internal ping takes up to 500ms or even times out and webinterface takes years.
    I've tried several firmwares (alchemy-pre7, alchemy final, talisman 1.0.4, hyperwrt beta 2.1, orginal 4.20.7, dd-wrt beta 23 crashed my router at all) but the above results were the best I got. MTU is 1492 what my ISP suggests, but under windows I reduced it to 1478 as packets above that value are fragmented for any reason.
    Anyone any ideas or another firmware that I could test?

    edit: WRT54G and modem are connected via 10MBit Ethernet and communicate via PPPoE
    edit: some more infos.. I hardly need any special function except port forwarding, so I deactivated things like QoS and other Services that I don't need. This gave me a better result than with all this features activated, but not better than the above values :(
    i.e. alchemy pre7a with QoS activated gave me only 4Mbps downloadspeed. :cry:

    You could try OpenWrt...

    that would have been my next choice. But I'll first have to get some things clear e.g. how I get the pppoe package without an internet connection ;)
    or maybe something with my settings is wrong?

    Everything that you need to connect via PPPoE is already included in the base image. Just flash the White Russian RC3 build, and it should work...

    ok, just installed openwrt and it works so far.. I already installed your webinterface.. and what should I say.. its perfect.. but as you may guess, i've got some recommendations ;)
    In wireless config:
    enable/disable SSID broadcast
    edit MAC-Filter
    And Port-forwardings would be cool..
    so far for now ;)
    btw. why is no openwrt forum here? ;)

    ok, for now I'll do the forwardings with iptables and test bittorrent, hope it works better than with the other firmwares

    You didn't mention whether or not your speed improved. (I assume it did but I'm curious and don't like assumptions. ;) )

    not really :cry:
    It is quite the same as with the other firmwares turned anything down.

    I'm thinking about testing the overclock function in openwrt, maybe that helps.
    I'll let you know later when I tested that.. I guess thatt will be tomorrow.

    add a fan to the wrt and then overclock the router to around 230mhz that improved my wireless xmit speed but i dont know if it would help you with your internet connection.

    it could

    other than that i am not really familliar with the word "broadband" cause i cant get it
    also i am not sure that you have the correct speeds for your modem it it is dsl and that doesnt have 6016 dl speeds that i am aware of.
    cable does and that speed depends on your neighborhood and how many folks have it in use at the moment.

    Doesn't sound like your router is the problem. The router should have no problem pushing that much data. My ISP gave us a speed upgrade from 3mbits to 5mbits 8 months ago. Most people had problems getting the new speeds. Most people got about 4mbits. It turned out to be the cable modem it self. Once my ISP replaced these older modems they had no problems getting the new speeds. BTW I have roadrunner. So maybe if your cable modem is 2-3 years old might be a good idea to have your ISP replace it.

    Well, first the overclocking.. setting clkfreq to 216 bricked my router. After opening it up and putting a 300mm 230V Fan in front of it I was able to put the speed back to 200 before it rebooted. So I guess overclocking is my last choice.
    The problem is definitely the router. With direct connection to the modem (modem directly into switch, laptop with PPPoE connection over wireless) I get ~710KB/s downloadspeed and with bittorrent ~400-500+200 direct download (didn't test it that long) btw. with this test you can see, that is not the bridge between wlan and switch, it has to be LAN<->WAN and my guess is that PPPoE isn't fast enough.
    to the modem, I even checked this and asked a collegue to come over with his brandnew modem, the result was the same as with my 5 years old modem.
    I do the download tests with testfiles from my ISP.
    So for me the WRT54G is the only possible bottleneck left :cry:
    btw. it is the same with my old router, but it has a notice on it "up to 4Mbps" and I get about 4.5mbps.. but linksys says up to 25MBps ;)

    edit: using my old router as switch didn't make any difference at all.
    As my old router is slower than the linksys it would make no sense using it as gateway

    I've never seen a WAN performance spec for the WRT... Where did you find this info?

    That's odd. While using WPA-AES, my v3 "G" can pull 24.8 (right on WIFI specs), and the GS can pull 29. It was only Avenger's HyperWRT 2.1b1 that could go these speeds. First I had to load Linksys 4 based firmware and then hard reset. (hard reset=plug in while holding reset). Orange light came on. Next I loaded HyperWRT and then did another hard reset. Orange light went off. Lots of speed, zero problems. Did both routers the same way and they work great. Oh, I almost forgot to mention. For some reason, QOS (listing all clients in MAC fields and not using ethernet port fields) incredibly increased the speed of the V3 "G" while the "GS" experienced no difference of speed by enabling QOS. Frame burst was disabled on the "G" because it helped, but it made no difference to the "GS".

    You can get those speeds out of the ethernet port, but not the WAN port. To support extra high speed internet, use an extra high speed stand-alone router or set your major downloading machine as the DMZ.

    There's also a trick you can try. If your cable modem is 192.168.0.1, you can set your wireless router to 192.168.0.254 to see if that will improve its routing speed, since it is now routing to the exact same network. ;)

    ummm your cable modem wouldnt be 192 anything because that is a prvate block of ip's and about every router comes out of the box with either that ir a 10.10 number


    your cable modem has an ip that your isp owns and it is a public address not a private address
     
  15. danielhaden

    danielhaden Network Guru Member

    Oh, I meant the nat side of the cable modem.
    It is already converting to the 192.168.?.* network, so you don't have to make the router do it again. Should you have a fixed IP address, then you would be in need of a pro router, of course.

    just got the WRT54G v5 and it has a serious bottleneck. had to manually set the MTU to 1500 and I still had a 25-35% degredation in speed compared to my box being hooked directly into the modem. It's probably a limitation with the broadcom chip.

    I think the problem is PPPoE. PPPoE connections seem to be very CPU intensive. I have only a 1 MBit/s DSL PPPoE connection. But even this connection, when downloading at full speed, is causing the PPPoE module to consume about ~20% of the WRT54G's CPU time.

    Recently 6 MBit/s DSL PPPoE connections have become widely available in germany. And suddely in a lot of forums people started complaining, that their WRT54GS's WAN connection is maxing out at ~5-5,5 MBit/s and that they can get the full 6 MBit/s only, when connecting their computer directly to the DSL modem. So I don't think, that this is a problem with some DLS modems. This even happens with ADSL2+ capable DSL Modems that are able to do 16 Mbit/s with other routers.

    It would be interesting so see, what the maximum speed is on DSL/PPTP connections. I think DSL in combination with PPTP is being used in Austria.

    Some DSL modems can be configured to handle PPPoE. If anyone has this type of DSL modem and WRT54G they can do routing performance comparison (PPPoE in router vs PPPoE in modem).

    For example the D-Link DSL-360T modem can handle the PPPoE connections itself. So you only have to configure the WRT54G(S) for normal LAN/DHCP internet access.
    I have seen reports, that the WRT54GS can do about 7,5-8 MBit/s with this modem. But that's a limitation of the modem, as the 360T can't handle more than 8 MBit/s. So presumably with another, faster modem handling the PPPoE stuff, the WRT54G can do more than 8 MBit/s.

    At least according to the test done by tomshardware (which was done with a LAN/STATIC WAN conncection and not with a PPPoE connetion), the WRT54GS has a WAN <-> LAN routing performance of ~34 MBit/s.

    I thought there was a sticker on the box which says "ADSL2+ ready (up to 25Mbps)" but maybe I remember wrong as I couldn't find that information anywhere else.
    Next week I'll borrow a WRT54GS (on 216mhz :)) to see if it performs better, we'll see :)

    If the slow WAN speed is caused by PPPoE eating up all CPU power, you could try to set the WRT54G to synchronous pppoe mode.

    This is supposed to reduce the CPU load, when using a PPPoE connection. Unfortunately some ISPs don't support synchronous pppoe (actually, at least here in germany, most ISPs don't support synchronous pppoe).
