ASUS WL-520GU wireless connection/speed problem

miller351 62 November 7, 2011 at 08:17 PM
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 flashed mine the day i got it with tomato firmware. I haven't had any problems at all. The stock firmware was horrible IMO. My suggestion is to try that ..

Almost reads like what little memory that this router uses is getting loaded down over time, no different than a computer and RAM/CPU being overly taxed. The more connections a router has to negotiate, the more it will start to flounder over time.

This router is DD-WRT compatible so I'd recommend upgrading the firmware to a DD-WRT firmware and see if it stabilizes.

Tomato firmware FTW!!! Get it from either PolarCloud [polarcloud.com] or from TomatoUSB [tomatousb.org]. PolarCloud is the original Tomato firmware, TomatoUSB provides some extra tweaks like VPN support.

BTW, I had one of these boxes running with stock tomato for almost a year in an unventilated cabinet on a shop floor. They are real champs.

tomatoUSB also has USB support (obviously) which polarcloud does not. Use that and take advantage of the usb for printershare/usb drives.

I saved each one of the files in the attached to my desktop. Which files do I upload and in what sequence?

Just use the standard generic file. Other versions offer different features depending on need. But standard generic is fine in most cases. If later you change your mind, just update the firmware again.

Updating is super easy w/ these ASUS routers. Always use a wired connection! Set the router to factory defaults. Then place the router in recovery mode (power it up while holding the reset button until the power led flashes slowly) and TFTP the file over to the router.

tftp -i 192.168.1.1 put dd-wrt.v24_std_generic.bin

The LAN led on the router will flash quickly until the transfer completes. Then let it sit for a couple 2-3 mins, then power off and on again.

Btw, if using Win7 and running tftp from the command line returns not found, you need to enable it under Control Panel->Programs->Programs and Features->Turn Windows features on or off (TFTP Client).

I have Tomato on mine and have great luck and stability. Highly recommended.

Do what eibgrad stated. I can't add much more to that at all.

LAN1 port on router was directly connected to computer.
- I set the router to factory default settings
- I placed the router into recovery mode (per your directions)
- The power LED flashed slowly and LAN1 port was solid
- At the cmd prompt I typed in "tftp -i 192.168.1.1 put dd-wrt.v24_std_generic.bin" and got the error can't read from local file
- The router default gateway IP was not available when I did a IPCONFIG all and when I went to IE and typed in the IP there as well
- I then unplugged the router power again and plugged it back in to restore it
- I put in the IP in IE and tried to upload the new firmware while logged into the router itself and got the following error:
Firmware upgrade fail. It may result from incorrect image or error transmission. Please check the version of firmware and try again.
- Tried it again (with the correct firmware saved to my desktop) and got the same error

What did I do wrong?

When using the GUI, it's more stringent in what it will accept (it may check versions, it may require the file use the extension .trx, etc.). That's why TFTP should be easier, it will just send whatever you tell it.

Why it couldn't read the local file, I don't know. Make sure to execute the command from the same directory that contains the file. You might try disabling your local firewall while doing the update too.

That seems to be the problem. I didnt execute the command at the same directory that contains the file. How do I "go into" the file where the firmware is? Isn't it C: then something else?

Ok. I am in the folder where the firmware is in the cmd prompt. I also disabled the firewall. Now to try it again.

It worked. I have DDWRT control panel for my router.

how do I either increase the speed or consistency to make sure whatever is using the wireless is not experiencing lag time, drops or buffering?

Have you tried it long enough with the new firmware to verify whether there is still that lag and/or drops in connectivity?
