Subject: Nic/router speed drop
Message-Id: <20100301004821.VQBX3908.mx-02mtaout01.mts.net@wnpgmb021pw-sp03.mts.net>

 My several month problem of local lan speeds through Linksys router suddenly dropping from 25-30Mbits to 56k modem speed
occurred again.  Internet side never changed much, LAN could zoom or crawl.  Followed Lewis's advice that Linksys was burning
up and replaced with new Dynex.

 With LInksys today get sometimes crawl speed, other times relatively normal and lockups on ftp transfer on local side.  With
Dynex get intial faster speeds and almost immediate lockup.  Thought occured perhaps nic's were not on same network speed.
Began modifying .nif files for each card as below.

 From Accton chip nif: 
[MEDIA]
 display = "Physical Medium Type"
 type = String
 strlength = 14
; default = "AUTODETECT"
 default = "UTP_100"
 set = AUTODETECT, UTP, UTP_FD, UTP_100,UTP_100FD

 Intel and Admtek also set same.  Tried full duplex 100 first.   Does above look suitable?  Is Autodetect better?  4 months ago
everything cruised along so something changed.

 On suggestion from this list ran Netio as follows with Accton chip as client.  Do these speeds appear normal?  Machines with Intel
and Accton worked fine in previous months.  Admtek recent addition and it could be swapped for other chipset.

 Since switch of router problem changed.  One part better, something else worse.  Is there a tool to determine what connect speed
2 nics connect at?
