Super slow wireless connection

Tp-link Tl-wr541g wireless router

Specs: Windows 7, 965/4gb
I've been trying to set up streaming to my PS3 using my TL-WR541G wireless router, and the speed I am seeing is amazingly slow.

Judging from streaming/copying files, the average transfer rate i'm getting over the WLAN is only 1.5-2.0 MBps. I've tried a number of things that should theoretically improve speed if there is a bottleneck (moving router closer, using a booster antenna, etc)

But here is the thing. I've got 100% signal strength on the PS3, and my estimated download speed from the connection test is a steady 3.5-4.0MBps. I just can't figure out why it is streaming video from the PC at only 1.5-2.0 MBps.

Is there some kind of setting under the LAN connection that could be limiting my speed, or anything else I can do to squeeze out another 1MBps or 2 out of what is supposed to be a 54Mbps wireless connection? It's killing me, because without that little bit of extra bandwidth i'm unable to stream the HD files I have.

Probably need more info.

Are you using security?
Do you have any wireless-B devices connecting?
Have you checked TP-Link's website for firmware updates?
Have you attempted giving the ps3 a static address in your router administration?
Do you have QoS enabled, with default settings? (No one device will ever get more than 50% of available bandwidth if so)

54 megabit = ~6.7 megabyte. Realistic data transfer rate for sustained throughput is a cumulative 3 - 3.5 mb.

In my personal experience, I found that even with everything optimized, 54 wasn't capable of streaming files larger than 1 gb/hr. 300N gave me approx. 270mbps, and even that wasn't fast enough to mount and stream bluray isos. Reasonable upper limits for me were 3gb/hour and I ended up giving in and running Cat6.

thanks for the reply.

I'm using WPA2-PSK encryption.
No wireless B devices.
Router's firmware is up to date.
QoS is disabled on the router (enabled on my computer, but I assume that shouldn't matter)
I haven't tried giving the ps3 a static IP yet.

Any other thoughts on what could be causing the slow speeds? I just did a file copy from PC to PS3 and calculated the average transfer rate at 1.6MBps. With 100% signal strength, i'm baffled as to why it's not higher than this. That's only 13Mbps, not even a 1/4 of wireless G's rated capability.

Turn off all encryption and compare speeds. If you get a big gain, just leave the encryption off and use mac address filtering to only allow your ps3 wireless access.

WPA2 uses AES only and this requires substantial cpu, and your router has an atheros AR2317 chipset. This is the chipset briefly used by Linksys in the WRT54G economy router. It had enough issues that Linksys scrapped the design and only made Broadcom models after that. I am guessing here, but perhaps that chipset isn't up to the task of AES encryption.

Unfortunately changing encryption and even turning it off didn't change the speed any.

Here's what really stumps me. I can run an internet download speed test on the PS3 and it consistently comes back with a speed of about 4MBps. If the PS3 can detect this high of an internet download speed, this must mean that my WLAN is capable of transferring at that fast rate, correct? Yet my WLAN transfer rates from PC to PS3 never above around 1.6MBps.

This seems to suggest to me that maybe there is a bottleneck somewhere on the PC. I'm running Win7 and have a beast of a computer though, with a Quad 965 and 4GB RAM. Is there any kind of network setting on the PC that could be limiting me to these slow speeds?

Sorry, I thought your ps3's wireless was where you were troubleshooting.

On your win7 box, the issue will always be one of three things - the wireless chipset is overheating, it doesn't get enough power, or the driver set has issues. If you get good data transmission for short bursts but sustained throughput suffers, check temps. If your card is internal, open the case and put a box fan blowing on it. If it is external usb and it gets hot to the touch, do some case modding. If it doesn't seem to get hot, then it isn't getting enough power and it has a fundamental design flaw that can't be overcome unless the manufacturer gives you a new firmware.

On the other issue, check the manufacturer webpage for driver and firmware updates. Latest doesn't always mean best, so try a variety. If your mfg doesn't have a recent update or a variety you can try, find out what the chipset is and find other manufacturers' updates for identical chipsets and try those.

If you reach the point where you want to spend money...

These used to be $70 and up, but wireless-g is fading.

It's actually a wired connection. Sorry, I should have clarified.
DSL modem is wired to Wireless Router.
PC is wired to Wireless Router.
PS3 is communicating wirelessly with the Wireless Router.

So what i'm seeing is: with DSL Modem->Router->PS3, I get 4MBps transfer rates.
But PC->Router->PS3, I get only 1.6MBps transfer rates.

So i'm thinking there is something wrong on the PC end. The thing is, I can still download on the PC at 4MBps from the internet. It seems like there is some kind of bottleneck in the PC uploading (but not downloading) over the wired connection to the router. Is there some setting in Win7 that could be affecting that?

Turn off auto-tuning from an admin command prompt:

netsh int tcp set heuristics disabled

netsh int tcp set global autotuninglevel=disabled

then reboot.
