    I have a WRT54GL router. It hangs :( Sometimes it hangs several times in a day. I think that this depends on the network traffic. If there is much traffic, (p2p, an other it hangs in a same day). I read in the forums that this is not a special circumstance...The solution can be to install another firmware...The question is what is the best firmware for my purposes...

    - I have theree machines and a hard client to listen music: a PC (P2P) a, Mac Powerbook (sometimes with wireless), a VAIO (always Wireless) and a Squeezebox SB3 Client (

    - I need that the new firmware let to install the original firmware

    - I need a firmware that always assign the same IP address to my machines
    (This is not present in the original firmware)

    - Last and very important, I dont want to brick the router, and I dont want that the router can be reset continously (as the original firmware)...

    With many thanks in advance

    For ease of use sake i would have to say Tomato. There is always a chance of bricking a router anytime you do a change of firmware though as long as you do it wired and do not power it off while in the middle, the chance of that happening is very slim.

    By the way, I read that Tomato uses SVG graphics, and this format is unsupported by Adobe now..Can this be a problem...May I use other firmware?

    Did you use Azureus and the Linksys official firmware...? The article tells about two non official firmware solving the problem DD-WRT and Thibor....

    If yo use thibor, you have not the problem yet :)

    Thibor's 15c and the official Linksys version v4.30.9 works well on AzureUs. I just prefer using Thibors 15c over the official firmware.

    Why dont you just flash with either firmware and see for yourself?

    Also another way to brick a router is by doing the firmware update with a wireless connection.

    Only do firmware updates with a wired connection. Wireless can drop out and leave you with a dead or bricked router.

    Thank you... I didn't know 4.30.9. I have 4.30.7. In fact this version is for WRT54 GL v1.0 and I have WRT54GL v1.1. I read the official Linksys forums because there is a client asking for this, and they told him that he must wait for 4.30.9 in WRT54GL v1.1

    Hmm, I didn't know you have v1.1... Only v4.30.7 is the latest for h/w v1.1. Anyways, if you don't like flashing it with Thibor or any other 3rd party firmware, try to lower your MTU settings. Lowering it down will prevent collision or packet loss on the router. Try 1400 and observe if it still hangs. I suggest an increment of 50 (1400, 1350, 1300 up to 1200).

    OK, I will do this...

    Thank you very much for your help

    According to the OFFICIAL LINKSYS FORUM v.4.30.9 works on both v1.0 and v1.1. It also appears the same is being said in the news section HERE.

    Thank you very much for your help...The Linksys official forum is a complete disaster...I read yesterday that 4.30.9 was only for WRT54GL 1.0

    I will write a e-mail to linksys support

    As you told me, the spanish suport tells me that 4.30.9 is valid for my WRT54GL 1.1...I will install as soon as posible

    This is not a problem. firefox supports this natively, and adobe has a plugin that gives IE support for it as well.

    It is curious but the link for v4.30.9 has a name ended is US...This is the US and not the EU version. I was told by the spanish support that this is not important..They differences are:

    - US version has no Spanish language..In fact I use it in english Now...

    - US version has no 12 and 13 channels...They told me this is not important for me...In fact the default chanel now is 11...

    Well, now I'm a bit stuck :| The router is so far beyond reach, but I suppose I'll have to cut and break and climb to get to it....

    Basically, I haven't got a clue what it's doing, seeing as I can't see the power lights etc.

    The LAN connection lights up when the power goes up, but I've tried pinging anything it could possibly be, and tftp'ing to it... nada. nothing. not a blip.

    Now, I have 3 questions, besides the OBVIOUS "WHAT IS IT DOING?!!?":

    1) What IP would it have if it's waiting for me to tftp something?
    2) Would it be waiting?
    3) Will it wait if I manage to press the reset button, (without dripping sweat everywhere..) ;)

    Thanks..... any advice/info is appreciated. I've looked and looked, hey, maybe I should find a bootup printout and try guess where it's dying.

    My guess is that my first mtd-write, wrote a little bit over the start.... So theres some Tomato 1.06, possibly a blank few bytes, and then a bunch of Tomato 1.04.

    Here's to hoping TFTP does the trick..... because I reaaaaly don't feel like building JTAG interfaces.... or... do :confused: Do I?

    Here's the joke for you, I've updated >10 WRT's via Wireless. Not a single hitch.

    And the one I do wired, bombs out. Turns out high-resistance CAT5 is more dodgy than wireless. :blush:
