Router losing attached devices

[ptoye]

My router (DG834Gv5) is losing devices when they reboot. I started with a clean router. Then switched on another PC. I could ping the new one from my own machine. THen rebooted the new machine. Ping disappeared. And it's not in the device list.

Oddly, I can ping the machine from the router.

PING 192.168.0.5 (192.168.0.5): 56 data bytes
64 bytes from 192.168.0.5: icmp_seq=0 ttl=128 time=47.6 ms
64 bytes from 192.168.0.5: icmp_seq=1 ttl=128 time=74.7 ms
64 bytes from 192.168.0.5: icmp_seq=2 ttl=128 time=100.3 ms
64 bytes from 192.168.0.5: icmp_seq=3 ttl=128 time=20.8 ms

Looks as if the router's forgetting its DHCP table - which of course isn't visible from the web management interface.

Anyone here got any ideas how to get rid of this amnesia? It's a 100% pain.

Hello ptoye

Have you tried to set up address reservation located under LAN settings this may be a fix to what is happening to you.

No, I haven't, Nor have I used pre-assigned IP addresses for the devices - it just shouldn't be necessary.

As I'm moving to a new telecoms (VDSL) service in the next few weeks, I'll have to get a new router. So I've decided to ignore it for the moment as we can live without it and hope that the next router works better!
