ASUS WL-520GU wireless connection/speed problem

miller351 62 November 7, 2011 at 07:17 PM in Computers (3)
I have a ASUS WL-520GU that has factory firmware.

A droid 2 phone, a couple TV's and a couple computers access the wireless internet regularly.

From time to time the wireless becomes slow, won't connect and/or has latency issues. I can tell this because my droid's wifi bar turns white (not sure what white means) and the internet has connection problems and when using netflix on the TVs, it buffers much more than normal. The wired connection I have to my desktop computer is not affected.

If I unplug the power from the ASUS for about a minute then plug it back in, the wireless connection goes back to how it supposed to be. This keeps happening.

Any suggestions would be appreciated.

I'm using this router with tomato fw and wireless speeds max out at 10mbps. Not sure if there is a fix for it. I've searched everywhere and found nothing. I had the exact same issue with ddwrt on the router.

Insufficient information. How are you measuring it? Over the internet (e.g, SpeedTest)? Locally between machines? Are they both wireless, or only one? Are you using something like NetCPS or Iperf for local testing? Is wired the same or different?

Do you have any 'b' devices that you might be using? If so, it might make the whole network run at 11mbos instead of the 54 for 'g' networks.

If the desktop computer is the only thing that connects to the router with ethernet cable and the rest is done through wifi, and the problem only started happening within a year or so, I would focus on overheating issue.

Tomato is the firmware I would use. Not only because the latest DD-WRT stable release was updated well more than 4 years ago, QoS never worked the way I expect with good stability, but also because it abused and violated lots of GPL licensed work from others by encrypting the code without releasing the source code when it pushed out the commercialized web ui in 2006.

Measuring via the network media streaming. I use PS3Media server to stream files from my laptop to my Playstation 3 and the files max out at 10-14mb/s (this is shown on the playstation and on the PS3MS. This seems slow and won't even stream small divx rips of video.

This seems like poor wireless performance because in the past I've been able to stream entire DVD5 videos (literally putting in a DVD movie in a dvd drive and playing it over the wireless by sharing the disc drive on the network) over my Linksys WRT54GL.

There are no B devices and I even went into the router configuration and set it to G only to make sure it wasn't running as a B network.

The laptop and the PS3 are wireless. Is this the reason it's going so slow? I guess if it has to contact the router and then send it it could be using 20-28mb/s (10-14 both ways). In the past I've done this with computers where one is wired in and the device receiving the media is wireless.

The only way media streaming can measure the max. network speed is if it saturates the network (the video start stuttering after the player's buffer runs out). It's better to do file copy and past between computers.

Please confirm the speed unit you're using is mb/s instead of mB/s.

What's the actual avg. network speed if you copy and paste files under the following two situations?
desktop -(wired)-router-(wired)-laptop and
desktop -(wired)-router-(wireless)-laptop
use a stop watch to measure the time and use a single file bigger than 1GB to do the test.

By comparing the results with your PS3 speed test (by file copy/paste not media streaming) result we will know if
1. if the speed bottleneck occurs on the wireless part of the router
2. if the speed bottleneck occurs on the PS3

Also it would be helpful if you provide the distance between the router and the wireless connected devices and if there is any concrete wall between them(where are the router and the devices located in the house).

20-28mb/s = 2.5-3.5mB/s which is pretty slow for G speed. From 5ft away between the wireless computer and a router (the other end is a wired NAS) normally I see 6mB/s speed (WRT54GL + tomato).

If both sides are wireless, this could be the problem. Remember, access to wireless is serialized. It's essentially half-duplex. When the router is talking to one wireless device, it can't do anything w/ any other wireless device, effectively cutting your throughput in HALF compare to having one wired and the other wireless. As you add more wireless stations, it grows only worse. Everyone is vying for access to the one radio freq and must take turns. Yet another reason why wireless sucks, esp. for server applications.
