I HAD a Netgear WGR-614 v7 b/g router and when I would try to copy files across the wireless I would only get about 15-20mbps max. I tried:

Changing the channel
Disabling the encryption
Disabling the firewalls on both PC's
Disabling the spoofed IP on my desktop
Disabling every other network service on both PC's
Disconnecting all the other devices on the wifi
Resetting the router's fw to defaults

Nothing made a difference, 2MB/s was my max. I bought a new router thinking that my old one could just be really tired after TB's of data running through it and the wrong power adapter one time (oops) so I bought a D-Link DIR-655. I figured with 802.11n & 10/100/1000 that I'd see a noticeable difference, however it wasn't what I wanted. Now I can get about 4-4.5 Megabytes/s (My network gadget says 35mbps is it's max) which IS an increase...
Can anyone help with this?

*Note* I thought it might just be the PC's which have a problem so I tried using my PS3 to copy something over the network & it only got 25mbps.



PC/Network info:
Laptop with an Atheros AR9285 b/g/n card
Desktop with a "Realtek Gigabit PCIe GBE Family" card. (onboard, not sure on the exact model though)
Avast v5.0.1289 Internet Security on both PC's
Comcast 16Mbps Cable Internet.
Modem is a Motorola Surfboard SB5101
DLink DIR-655 b/g/n with 1 PS3, 1 Wii, 1 Laptop & sometimes a PSP/iTouch on wifi, 1 Vonage VOIP box on Ethernet

"would only get about 15-20mbps max"
"My network gadget says 35mbps is it's max"

At 54mbps that would be about right.

Just so you know;
your internet speed doesn't matter in a peer to peer local lan transfer
your wifi stats are great. no channel contention.

if your built in wifi card can support n you should try connecting under n. Doesn't appear you are.

I just threw my internet info in, I know that you can't expect to get 100% of the "rated" bandwidth from most routers but I do remember getting like 80-90% in my old house with no other wifi networks around. My router says that my laptop is connected in n mode, says something like 65mbps which I find weird. I though n was WAY more than that, could there be something wrong there? I just updated my drivers from version 8.something to v9.2 Atheros drivers instead of MS' built in drivers.

This may be a dumb question; will having b devices connect to the router cause it to drop the speed of the n devices connected? I heard from my boss once that some routers will drop all wifi connections to the rate of the slowest device connected. (Not sure if he's right on that)

This' from my router. I noticed that my Wii which IS 802.11g is only connected at b speeds even though the router says "mode 802.11g" I remember one time setting my router to g&n only and it forced the Wii to run 54mbps.

I'm only able to get 8mbps transferring files to 2 devices that are on the wireless. I can get 25mbps only if I am transferring files from my desktop on ethernet.

TCP_Out-Of-Order issues.

Hi I have been having some pretty sever issues with my wireless network, especially with my laptop's Atheros 9285 card (that I have heard is basically a turd with bits of gold sprinkled on it) such as low transfer rates, packet out of order errors, sporadic connection rate reading from my router, etc.

Right now the problem is transfers through the wifi from my laptop to my PS3 causing TCP_Out-of-Order, TCP Dup ACK, TCP Fast Retransmission & TCP Window Update about every 5-20 packets according to WireShark.

This is not normal from what I have seen of transfers from my pc to my laptop & vice versa, however I only connect to my DLink DIR-655 at 65Mbps normally & it fluctuates to 120, 130 & 150. I get about 4-4.2 Megabytes/ps pc - laptop and only about 700-800K from laptop to PS3. My friend brought his laptop to my house and going from his to my laptop only got about 300-400K, the same bad speed as the PS3.

I am by no means a networking expert and I could really use some help of making heads or tails of all of this, I have the Xirrus info for my network in this thread here: http://www.techsupportforum.com/forums/f31/wifi-bandwidth-issue-602911.html#post3451503. There are a LOT of wifi networks in my area and I have the channel set to auto but it picks weird numbers like 2 or 7.



Thank you forum users!
