Hi,

I recently bought asus wl-500g and installed firmware http://downloads.openwrt.org/people/nbd … s2-4MB.trx.
Every time I try to download bigger files (over 100 MB), router reboots. Usually I get less than 30 MB before transfer stalls, sometimes it goes as far as 80 MB.This only happens when using pppoe protocol and only when I'm downloading big files. Uploading works fine. (I tested it by sending 700 MB file. 10/10 times it completed OK with speed 1.1 MB/s) I have redirected system logs to remote host and I'm running pppd in debug mode, but there's nothing special written in syslog at the time of reboot (just normal boot messages). I have also tried to reproduce this situation in my home network, with static IP associated to WAN port. I have been transferring big files back and forth without problems so i think something in pppoe is causing reboots.

here's some (hopefully) relevant NVRAM entries :

root@OpenWrt:/etc/ppp# nvram show | grep ppp
size: 967 bytes (31801 left)
ppp_passwd=*******
ppp_username=*********
pppoe_mtu=1492
wan_proto=pppoe
pppoe_ifname=eth1
pppoe_passwd=*****
pppoe_username=*************
wan_ifname=ppp0
ppp_mtu=1492
pppoe_mru=1492

In the beginning of CHAP authentication there's syslog entries like this :

Nov 21 17:58:51 192.168.1.1  pppd[292]: Couldn't increase MTU to 1500
Nov 21 17:58:51 192.168.1.1  : Couldn't increase MTU to 1500
Nov 21 17:58:51 192.168.1.1  pppd[292]: Couldn't increase MRU to 1500
Nov 21 17:58:51 192.168.1.1  : Couldn't increase MRU to 1500

but authentication succeeds and everythings is working fine until incoming traffic gets too heavy.
I have searched forum and read the documentation, faq and logs but looks like this isn't too common problem.
Well, I found this :

but I've already done that so any help is much appreciated.
