Hello..

I've been having some network speed issue for quite some time now and was hoping for some insight on what may be the cause.

Setup is this..
3 PCs connect via CISCO SR224 Switch 10/100 24-port

The Switch connects to Netgear N300 Gigabit Router model: WNR3500v2 Router with 3 more computers and multiple Wireless devices.

Then the N300 router connecting to the Time Warner Modem.

My concern is this..
I do a lot of large file transfers from my 3 PCs (on the switch) and my thru-put has dropped badly.
I use to push around 100mb/sec and now I am lucky to get 10 to 13mb/sec

I've fiddled with the NIC properties HERE and cannot for the life of me figure out why it has dropped.

I do have a second NIC card installed on one of CISCO Switch PCs and was thinking of getting another NIC for the other CISCO Switch PC.

What suggestions would any have to again reach maximum LAN transfer speeds?

Yes they are gig..  I was mistaken though.. It is a CISCO SR224 Switch 10/100.. Had my hardware mixed up a second there.

One NIC is the built into my ASUS P9X79 which is GIG.. And the other(s) are.. Both RealTEK - One is PCIe GBE and the other RTL8139/810x

 

I have the RTL disabled atm.

It has been sometime since I pulled those LAN transfer speeds and was hoping to again.

Can't find that model #... did you mean SR2024?
