WRT54G connected to token ring network - packet loss

    I have a WRT54G connected to a token ring network, and now we are experiencing high packet loss.

    Is there a problem with my configuration that is causing the problem?
    Or I guess a better way to put it is What SHOULD my configuration be?

    Was just wondering if this was causing a blackhole in the network causing the dropped packets ....

    The wireless PC is running Zonealarm firewall too, if that makes a difference.

    Thanks !!

    Token Ring is an IBM protocol. Ethernet is CSMA, and the two are not compatible.

    You cannot simply plug these two networks together. Are you using another device, or protocol converter, between the Token Ring network, and Ethernet network? You haven't supplied enough details to offer any suggestions, unfortunately.

    I do not know all of the Network details, unfortunately. But we have a Token Ring network which most of our PC's are connected to. But we also have an ethernet hub connected to the token ring hub. (I am assuming this must take care of any conversion taking place)

    I plug into the ethernet hub and connect this to the internet connection on the back of the WRT54G. I am then able to connect to the network with my laptop. The only problem is that we have been experiencing hi packet loss on the token ring. Linksys tech support assures me it is not due to the router and that the router configuration does not matter (ie: router setup as a router or as a gateway etc.) ... but I just wanted to make sure.

    I believe that token ring networks pass packets around the "ring" to each computer. Each PC then examines the packet to see who it is designated for. If the packet is not designated for that PC, then the packet gets sent along to the next PC. Otherwise, if the packet has reached it's recipient, the packet is taken off the network by the PC and not handed on.

    I just wanted to make sure the WRT was passing the packets along instead of just becoming a "black hole" that drops the packets. I also was wondering if the configuration did indeed matter ...

    If the router is acting as a gateway, I would THINK that the router would examine the packits and pass them along if they did not belong to anyone on the wireless portion of the network. But if it was configured as a router it would pass the packets along across the network where an improperly configured PC could be the cause of the packet loss ... ???

    Sorry for the long post .. and thanks again for your help.

    token ring uses a different standard than wireless: thats y u have high packet lose... token ring in on IEEE 802.5 i beileve and wireless in on 802.11x so u cant just connect 2 standards together like that...u need a gatway of some sort or a media device...or just plain upgrade ur network bc token ring blows bc it was made by IBM and it suxs...it would be a BIG project but it would most deff open u to SO MANY new things...and u will have a high speed throughout the network...so i how this works for ya
    email or IM me in u have ne more questions....
