We started moving our office to a new building last week. Friday, the T1 was switched to the new site. The data feed (fractional T1, 8 voice 512 data) runs to a new Belkin N1 Vision wireless router, with wireless disabled. FWIW, the wireless feature was working just fine with my iPhone in a test before being disabled. I had to replace our old Linksys from 2005, as it seems to have gotten fried in the move. Might as well plan for the day in which I finally lose and we turn on wireless.

One cable goes from the router to the server. This works just fine, full internet access. But another cable goes from the router to a new 3COM 50 port "4500" switch. No joy. Cannot access the network or internet from a workstation. I've tried plugging the router in to different ports on the switch, but I can never "see" the net from a workstation. Only patched in one workstation so far. However, at some point I must have done something right, because I found that Outlook had downloaded my email from the server. But I changed the configuration since then and have been unable to duplicate the feat. Crossover cable not required.

There's something simple I'm overlooking, but what?
With this move and the long hours, in which many things have gone wrong (including with the new PBX), the access and alarm system contractor underperforming, my desk collapsing, being very shorthanded and then having a close friend pass away rather suddenly, I'm just not thinking straight.

If I can stabilize the network, then I'll experiment with moving server and one workstation to the gigabit ports on this switch (assuming they are there for more than just cascading). In a distant future, we'll move to a full 48 port giga switch, but the bucks just weren't here today.
 
Have you checked to make sure the IP addressing is correct, mask, default gateway and DNS servers? Can you ping the inside address of the router to see if you're at least making it there?

Yes. Wireless is shut off via accessing the router from the server. IP adds were input by Cavalier tech, and yep, they're correct.

I checked my driver's license to make sure my name wasn't Bob. ;)
 
I suppose it wouldn't hurt to try that, but with a straight thru it downloaded email. Once.


This is the switch. Doesn't seem to require a particular port. Maybe I'd better read more carefully.

This
is the router. Despite the sales critter's claims that it would work right out of the box for wired, with no setup - 'tweren't so.

I think I'm going to have to take whatever ideas come up today and go in to work tomorrow to try and figure it out.

Many thanks for any and all ideas.

Probably doesn't require a crossover, but it isn't in the specs on the router that it is auto MDI/MDIX.

You're going to have terrible performance to the open net with 512K access. I hope speed isn't of the essence in your environment.
 
Actually, we have a multi-step plan:
-Move T1.
-Drop one assigned phone # from the 6 in rollover that is a favorite with telemarketers trying to contact a company that dissolved over a dozen years ago.
-Move phone # from analog temp line into empty rollover spot.
-Triple the speed (2 possible choices here, both must be tested). Probably end up with two T1 lines.

Probably going in tomorrow to work out the problem. Driving me crazy wondering about it. And can't go more than another day without a functioning network. Only getting away with it this long because people are still moving desks and computers. If brain doesn't shift into gear, will have to call in our outside support people. Bugs me how much I've lost due to non-use over the past few years.

Anyway, wouldn't it be odd that the direct server to router connection works fine, but the router to switch to patch cord to workstation doesn't? Crossover wise, that is.
 
Should have listened more carefully to RAD. Belkin was IP'd ending in 2.1 for some reason. Should have been 1.1.

All is well now. Thank you all for your help.

Sometimes 20+ years in networking comes in handy;)

Glad you got it fixed.
