New Around Here
I used to be in the computer business but I'm now medically retired however a Dr. Friend asked me for some help I thought I would post here to hopefully get the best current advice for what he needs.

their new medical software is web based running a java script and the newwork is now running very slow

currently they have a 150mbps Comcast connection going thru the comcast modem connected to 3 JFS524 E switches and behind that there is 7 8 port switches and 31 5 port switches. the network congestion is wicked. there is about 30 computers 10 tablets and about 25 VOIP phones. for wireless there is 6 - E4200 V1 routers configured as access points running DD-WRT

My thought was to put in a Dual Wan VPN fire wall with a cell modem for backup service connected to 1 - 48 port SMART switch for one floor and a 24 port SMART switch for the other floor. then behind those put 7 - 8 port smart switches and 31 - 5 port switches.

any advice would be highly appreciated I had been looking at the netgear products to do this but I don't know what the current best answer is.

if this is posted in the wrong place please tell me where you would advise me to post it.

Thank you again and by the way they want to do this like yesterday.
 
What does medically retired mean?

Hmmm, I would be getting a professional to see this in person. Forums are not the best for business decisions.
 
Start by analyzing network traffic flow to find out where the pinch points are that are causing congestion before you do anything.
 
can you advise what to use to test for traffic flow? I have a few pcs that I could use. the current modem / router is a cisco 3939B

connected to that in ports 2,3 & 4 is the 3 JFS524E netgear prosafe plus switch's I'm trying to make a decision asap as they are in a big rush. Thank you

re L& LD Medically Retired means due to a medical reasons I am no longer able to work, and I understand the other thought but thats not really an option

Looking a little closer, I see you are dealing with unmanaged 10/100 switches.

So a reasonable first step would be to replace the mishmash of 10/100 switches with Gigabit managed switches for each floor. I'd also replace the 8 and 5 port switches if possible, directly running those links to the main switches. Or at least make sure you don't have cascaded smaller switches.

Once you have the large managed switches in place, you can use the port statistics to see where the big traffic flows are and go from there. Managed switches will also let you aggregate links to get higher bandwidth between switches if needed.

I have no specific recommendations on switches. Just look for "smart" or layer 2 Gigabit switches.
 
Can you draw a diagram for us? How is a modem connected to three JFS524 E switches? The bottleneck seems to be right there with that dinosaur 10/100 switch. Are all other switches also 10/100 too?

I don't see a need to analyze, specifically; measure, the traffic. All that is required is to group clients that work closely with each other on the same switch and all clients that need internet access should have equal access to the outside. This is accomplished by using a single switch with enough LAN ports for each group. And of course, make these and all other connecting switches, GB switches too.

How are the connections to each group of clients made? Do they all run into a single location, or are they haphazardly strewn across the premises?

If they all run to the same physical location; a few judicious connection decisions on a single GB switch or a 4 smaller similar switches (one for each LAN port of a recent router) will make a world of difference in the responsiveness of the network.

With a more decentralized wiring setup, it may be still possible to do the same thing. But more than likely you will have to compromise between best inter-group interactions vs. balanced Internet access.
 
currently its a nightmare setup as follows

Comcast cable into Cisco 3939B Modem router
Port 3 of the 3939B goes to a different floor and is connected into a JFS524E
That JFS524E has ports 1-19 being used only about 1/2 of them have devices connected the others pretty much each have a basic 5 port switch with a mix of VOIP Phones, Computers and a few printers

Ports 2 & 4 of the 3939B is connected to 2 more JFS524E's similarly configured about 1/2 the ports in each one have jacks that aren't currently in use the other half of each one is again a mix with most of them having 5 port basic switches and a mix of Computers Printers etc and VOIP phones.

I was considering having the Cisco 3939B reconfigured in bridge mode

I was going to come out of port 1 into 1 of the 2 Wan ports of a Netgear FVS336Gv3 Dual Wan VPN Firewall with automatic fallover

the 2nd wan Port of the FVS336Gv3 I was looking at a GSM ATT modem for backup Wan.

for the Main floor I was going to come out of the Lan Ports of the FVS336Gv3 into

1 Port to Main Floor into a Prosafe GS752TP 48 port smart switch to replace the 2 JFS524e's

1 Port to main floor into a Prosafe GS724Tv4 24 Port Switch to hard wire some of the current devices rather than using basic Switches

I was going to connect a total of 6 GS108T-200 8 port Smart Switches spread across the 2 above switches.

out of a 3rd port of the FVS336Gv3 I was going to run to the other floor and connect a GS724TV4 to replace the JFS524e and I would run some new wires to the 5 unused ports and then I would also setup 4 of teh GS108T-200 smart Switches as needed.

I had hopes that the NMS300 Software would enable me to monitor what was happening with everything but my hopes is the smart switches would configure as needed.

on each of the 2 floors I also have 3 Linksys E4200V1 running DDwrt as a Access point for wireless.

Does this sound like it should work? am i screwing up? is there a better way to go? I'm also hoping that the firewall would take care of the HIPPA compliance issues.

thoughts? or other ideas?
 
A diagram would really help as you did not answer any questions directly...
