Loosing connectivity

[techsales]

I have a small business network setup:

1 workstation with Windows Server 2003

4 client workstations w/winxp

Lynksis SR216 switch

Lynksis BEFSR41 router

ATT speedstream 5100 modem

Using ATT basic dynamic IP addressing

I have recently been experiencing increasing intermittent loss of connectivity to the server and internet. No trouble can be determined on the ISP end and the connectivity loss affects all stations. I get the balloon pop-up which warns about LAN connectivity loss quite frequently also, on all clients. I did a little self help research and find that static vs. dynamic IP addressing may be a culprit or compatiability issues with the switch and router that is being set up with the ATT modem.

Not much here as I am not sure what exactly to ask. I guess I'll start with:

Should I be using static IP's for 5 worksations or should dynamic IP be ok? Does this even matter with the server PC as the other workstations are able to access the server PC even when internet connectivity is lost?

Does anyone know if these Lynksis devices are ok to use with the ATT modem?

Thanks in advance!

I would say that, if you get that warningballoon, the switch is the culprit.

Have you temporary tried another switch.

When your LAN has a DHCP-server, all workstations will only ask for an IP

once, so effectively after getting a valid IP they will just operate as

a statically assigned PC.

The only refining I'ld like to add is: do the workstations get their IP's

from the router or the modem?

(It shouldn't have anything to do with your connectivity problem, though).

Thanks for the info Peter. Kinda validated what I thought about the switch. As for the IP addressing per client, I am fairly certain this is obtained via the router.

Thanks again!!!
