At work we've got a business package cable connection that leads directly into a D-Link DIR-655 and then from that a single CAT that leads into the first port of a D-Link DSS-16+

Cable Modem > 10/100/1000 Wireless Router > 10/100 Switch

Over the past couple of weeks we've had the network slow to near zero connectivity (seemingly because everyone jumps online at the same time and overwhelms the DIR-655).  At most (currently) we would see maybe ten computers active on the network but usually closer to six... Should the DIR-655 be able to handle this concurrent wireless and wired traffic?  Is it likely because of the out of the box firmware it is running?

Should I be talking them into running the 1.33b02NA firmware or should we be looking into a more robust router which we then plug both the DIR-655 and DSS-16+ into?

There's a lot of possibilities here and it could be multiple things.

Is this a new setup, or did it start happening recently?

When the network slows way down, can you still access the web admin page at full speed?  (http://192.168.0.1)
Does the ping time to the router change?

When I had bizarre delays like this, I also tried accessing the cable modem's web page to see what happens and pinged the modem through the router.  If you can access your cable modem that might give some useful feedback as well.

That's what I did anyway to narrow down the chances that it might be the router instead of the network.  Others may have additional ideas.

Just curious, what speed business cable speed did you get?  Is anyone running a torrent?  All PCs have anti-virus software installed?
