D-Link G624T, with RT v2.6 firmware, hangs after 12 to 16h.

[sbicty]

Hello All.

1st I'd like to thank the RT team for their gr8 work.
I've recently installed v2.6 firmware on a D-Link G624T router and I was amazed by the functionality expansion and the control power I've gained over my router.

The only problem I’ve encounter is that router starts responding really slow after some hours of continue work (12 to 16) and eventually strops working.
I did an extensive search on RT forum and it looks like a low memory problem. The suggested solutions are to disable USD functionality and alter memory optimization Cron job to run more frequently. Unfortunately I could figure out how to make those changes.
I would appreciate if anyone can help me on how to configure my router to make it more stable.

This is a dump of router settings:

Glad you like the firmware

In the firmware documentation you can find things such as running the following from telnet prompt to disable USB

Code: Select all

setenv usb_enable "no"

To run the memory optimiser every hour the command is

Code: Select all

setenv memchk.sh "1"

The commands aboce add entries to the environment that will be read as the router boots up, so once added restart the router.

Also make sure that any features you don't want are disabled - IPAccount, UPnP for example. These can be configured from the web interface.

My router on 2.6 has been up for 159 hours and maintained ADSL sync for the last 154. I've gone with disabling USB as not needed and I run the optimiser every hour and it has kept the router nice and responsive for me.

TY 4 the quick and accurate answer!

[mysticalos]

ha yeah i was gonna suggest same thing when i first read thread. disable USB, mem checks. disable wireless if it's not being used. the dlink runs dog slow and does crash if memory is low.

[vrysera]

thank you
