Re: Interesting problem with Shaw internet - anyone
Thanks for your thoughts – Sorry I may have confused you earlier. So to clarify again….When I mentioned “bindings” disappear, I meant IP assignment from Shaw modem side disappears.
My server’s IP bindings to its network card remain functional all the time. NIC passes all diagnostics as well. IP is hard coded in TCP/IP properties. There is no DHCP.
And I’ve tested this many times by temporarily connecting a hub to server NIC and confirmed I can reach all IPs bound to Server’s network card from a test laptop. All services bound to each IP can be reached and server functions correctly.
In a support call, Shaw tech can reach modem and he confirms it is provisioned correctly, but Shaw tech himself cannot see the IPs when they disappear from modem.
I don’t know what they are doing. Rebooting the modem does not fix problem. All signals levels are fine and modem logs say modem remains online all the time. When one IP disappears, normally other IPs remain functional.
This windows server has all UDP packets filtered, so DHCP packets sent from Shaw from UDP port 67 are dropped. Windows DHCP client service is also disabled. Server has functioned flawlessly in this fashion for past 4 - 5 years and IP assignments have never faulted.
We have also replaced Shaw modem with new Motorola 5102. (I mentioned Motorola5210 earlier which was a typo).
My understanding is that… unlike Telus, Shaw does not use DHCP to assign IPs when customer has static IP. I have checked... IP assigned by Shaw to me are all static. My understanding is Shaw assigns IP permission to modem… and …modem and network card of customer device exchange ARP packets. Shaw router asks network segment broadcast address: who has this IP=xyx? Device says IP=xyz is at aa:bb:cc:dd:ee:ff Mac address… and this interaction is repeated and cached by Shaw router many times. Very much appreciate if someone can help.
IP assignment Problem still persists. |

| Here's what you can do, PM me and I will set you up on a Telus business server ADSL package for a month, to see if your network is wonky or something...
...Telus doesn't have contracts anymore on their residential internet service, not sure about their business service though.
...if it isn't your network on Telus's service, than it must be a Shaw server issue. At least you'll have some ammo to go back on them with. 
PS: I would probably ask Shaw for another modem to try first.... |

Canada | $96.95 for one month with no contract on a 3Mb down 1Mb up Server Plan, 2 static IP's...
It is a bit pricey just to see if it's ones own network is at fault or if it's Shaws, but the option is always there for troubleshooting... |
