[Logic] Linksys Router - Losing Telnet Connection

[Hank Phillips]

Rich,

For what it is worth, we tried Linksys stuff as a DSL access router in my 
credit union's IT department.  It never worked properly with BellSouth's 
DSL implementation, but the bigger issue maybe Linksys's implementation of 
PPOE (point to point protocol over ethernet).  Periodically, your provider 
will tear down the IP connection and re-issue IP addresses to those 
stations still on the network, in an effort to make an IP address pool go a 
bit further than it would otherwise.  Although I haven't looked at this 
transaction on a network analyzer, I think that the Linksys frequently 
fails this re-negotiation process.

I have had a lot of luck with Netgear stuff over most media types (DSL, 
Cable, etc), and they have upgradeable firmware.  You can get Netgear stuff 
from Office Depot, Best Buy,  or over the Internet from lots of 
suppliers.  Their stuff is also built like a Henry amplifier .... heavy 
enough to defend yourself in an altercation if you can pick it up and throw 
it a few feet.

We have since moved the credit union to a real business solution (T-1, 
Cisco router and PIX firewall and so forth), but if you have any networking 
questions, I would be happy to try to help.  I make some claim to do this 
for a living.

DOCIS stands for Data Over Cable Service Interface Specification, and 
specifies signalling standards for cable based data networks.  If you are 
having trouble sleeping you can check out this link:

Otherwise, buy Netgear and work DX.
