Network Topology

I have a small network that accomodates Vista & XP machines. I'm using an 8

port Netgear gigabit switch between the machines (which all have gigabit

NICs) and a Linksys BEFSR41 router for internet access and firewall

protection. I just replaced the Linksys router, so it is a recent revision

(I haven't upgraded the firmware on it yet). Connecting the machines, switch

and router is CAT5 cable.

 

Question:

 

Are the CAT 5 cables introducing a bottleneck into the network? Are there

any settings for the router that could be changed to produce higher speeds

over the network and internet? I'm on a cable connection.

 

Thanks!

Not likely that the CAT 5 cable is the problem unless it has not been

installed properly or has been damaged.

If you are using for example 5 PCs connected at the same time to the

Internet and doing large file transfers, then the speed of your Internet

connection to each PC will drop noticeably.

You'll never see gigabit internet speed in your lifetime. The speed across

the WAN port on your router is most likely 10Mbit, and your cable modem (or

DSL) is running at 3-5Mbit. You'll just see excellent transfer speeds

within the network... but then you could be running into an issue where your

harddrives aren't spinning fast enough to read or write the data to keep up

with the network.

 

My home network is pretty "zippy" even at 10Mbit--what else am I doing w/ my

time that I need to be in gigabit rush??

Cable internet ISPs top out at about 6 Mbps bandwidth. The old 10-

Base-T connections on Cat-3 wire can support 10 Mbps which is higher

than your ISP can provide. Using Cat-5 wire into a 100-Base-T router

connection assures you that this is not the bottleneck. Your internal

network should work very fast but all your machines must share the

slower internet connection bandwidth. Just make sure that all your

gigabit cables connect up all 8 wires for Gigabit speeds (10/100-Base-T

only requires 4 wires and some cables are made that way).

As previously stated, most high speed Internet access wire speed are

below 10Mbit. You will be unlikely to ever find a Gigabit Internet

access connect. Most DSL/cable provider have not ever consider to

only be an Internet access company so they "cap" the access over the

wire for their "shared" service (DSL/Telephone, Cable/TV.) The only

place you can find any type of bottlenecks is on your "local area

network" (LAN) in the form of:

 

Bad CAT 5 cable (CAT 6 should be better but more expensive!)

XP Pro (10 user can access on XP PRO shared PC at the smae time.)

Viruses and Malwares (anti-virus and anti-spyware a MUST, not an

option!)

Re: Network Topology

 

Thanks to all for the responses. The reason I ask is that my speed seems a

bit slower than it did before I replaced the netgear switch (previous switch

was gigabit 4 port) and linksys router. Also, I recently set up Remote

Desktop Connection between a few machines and it seems somewhat 'jerky' and

seems to respond a second or two behind. I was told in these NGs that this

was not normal. Any thoughts?

 

Thanks again,

Jack

You should know that routers are not all created the same. Each

rounter manufacturer create their own unique router controls. Some

"may" include different "services" so it is possible that routers of

the "same" speed can truely have different "access" speeds.

RE: Network Topology

 

Don't overlook the possibility that TCP settings (MTU, MSS etc) may be

different on the new router. This is more likely to affect PPPoE links than

PPPoA.

 

If the MTU is 1500, then try reducing it somewhat, say to 1460.

 

MSS should be 40 bytes less.
