Hi,

Problem - I am getting very sporadic transfer times across my network.  Can someone help please?

SETUP -

Lounge

Router 8mg ADSL Wired to NETGEAR WNHDE111 - acccess point running wireless N (forced to run in wireless N mode only on 5ghz range to avoid interference)

STUDY
Bridged to PAIRED WNHDE111 in study - wired to the 5 port Netgear gig switch, which NAS, VOIP BOX & PC (gig) connect to.

ABOUT HOUSE - Wireless N laptop signal around 80 %.

Ok here are the results;-

<><><><>
Based on a 63meg file
<><><><>

NAS to PC = 22 meg second
PC to NAS = 2.68 meg sec
NAS to laptop = 1.8 meg sec
laptop to NAS = 1.8 meg sec
PC to laptop = 1.67 meg sec
laptop to PC = 1.8 meg sec
Laptop (WIRED TO GIG SWITCH) to PC = 31 meg sec

Do you have WPA2 AES security encryption enabled on your wireless access point?  Possible neighbor sucking up bandwidth.  Anything less than that encryption level, is very easily compromised, by someone near you with a packet sniffer.  No security at all, is also bad : )

Looking at a diagram using the info you gave it looks somewhat normal.

The laptop appears to be slowing the other wireless devices down since the wireless speed between the PC and NAS is faster( mostly from NAS to PC)

You have pretty good speed between the laptop and PC using a wired connection although you don't say what the wired speed is between the NAS and PC. The wired speed between the laptop and NAS seems like it's not as fast as between the PC and laptop.

What I would do is check the setting on the laptop wireless to make sure it matches the wireless settings speed on the PC and NAS.

You might also want to check the wired connection speeds among the three to make sure they are using the same duplex, 100 full, 100 half etc. You have a GB switch but what is the wired LAN port speed on all three devices?

jkockler: - I have ACL enabled with a very long password, so they won't been sniffing the traffic.

The security is WPA2 with a 14 character password.

<><><>

wirednet - The laptop was running at 1 gig when connected directly to switch.

PC actual connected speed is 1 gig (represented by a green light on the switch) running at full duplex.

Laptop when wired is also 1 gig showing as 1 gig.

Laptop connection speed wireless is 91meg

VOIP = Vonage doesn't advise on speed.  Connected via HTTP to VOIP and checked all settings, nothing about connection speed or type.  It is however showing as orange which means 100 meg. Its a Vonage VTA box.

Download and install WireShark.  It is a packet sniffer that you can run in "promiscuous" mode, which will show you all the traffic crossing your network.

It will take some practice and some getting used to, but there are tutorials for it all over the web, and on youtube.  

It is possible that you have a bad NIC on one of your machines, which could be sending a lot of unnecassary packets, and taking bandwidth.  You will be able to see it all with WireShark.
