Re: [SLUG] Dlink Adsl Modem dropping Packets
What I have found with D-Link wirless routers is that after 24hours of use I have to cycle the power of the router. after calling D-link about this problem I am told to reset the router to factory default. second call was check the MTU, then my third call was to set short preable to off. next time I will be thinking twice about their products Ryan Verner wrote: On Sun, 2005-08-07 at 12:39 +1000, [EMAIL PROTECTED] wrote: 1.

I had a similar problem with a D-Link DSL-302G ADSL modem. It would overheat
when exposed to high UDP packet loads, which occurs when using BitTorrent and
eDonkey. I called D-Link three times, each time being put on hold for over
four hours (no joke). Their advice didn't help, and finally they agreed to
replace the modem. This didn't do anything, either. I finally gave up and
bought a ZyXEL 660RU instead (the D-Link's warranty was long finished by that
time). I haven't had a problem since.

[SLUG] Dlink Adsl Modem dropping Packets
Sluggers, I finally gave in with my Telstra connection and did the configuration the Telstra way. That is the D-link 502t Adsl modem is in routed mode, it does the pppoa authentication and Telstra provide another /30 address block to put on the ethernet (lan) side of the modem. All appears to work fine except after about a day or so the modem starts to drop packets. If you try to connect to the modem itself on either it's ethernet interface or it's adsl it makes no difference. So I'm pretty sure the problem is with the modem. This very quickly gets worse rapidly going up to 50% and soon after to 100% packet loss. If you re-boot the modem it recovers and all is fine for another day. It feels like some sort of buffer overflow. The mtu on the WAN connection is set to 1492 (as per default and Telstra's instructions) so I put some traffic shaping on the Linux firewall that is connected to the Modems ethernet interface to try to keep the packet queueing away from the modem. That appeared to work for a couple of days but then the modem started to dropped packets again. If you leave the modem for a long period it doesn't recover. Only a reboot fixes it. Hard to believe I know but a daily reboot is not an acceptable solution ;-) The Dlink adsl modem is an embedded Linux device. When it's not dropping packets I can connect on to it, play with the iptables, route tables etc. If only for the sake of Linux's reputation as a great network OS I'd really like to get the D-link adsl modem working. So before taking it up with D-link, I thought I'd ask the collective wisdom of Slug for any cluesticks. So after that long intro, to my actual questions: 1. Do I just have a bad apple and should I just get a replacement or is the a fundamental problem with this model of D-link modems? 2. Is there possibly something wrong with the config that a change to something like the mtu will solve? 3. Should I just give into the word on the street that dlink are crap and go get something else?
