Re: Interesting problem with Shaw internet - anyone
Have you a second machine you can replicate issue on? That would point to OS issues.
You suggest that this is episodic. Which means that sometime it is fixed. What seems to fix it?
Also, try enabling DHCP. If that works it would suggest to me that issue is provisioning and registering your machine on the network.
Does NETSTAT -r give you any insight?
I have seen something similar with Digital Phone Service (different cable provider), where failure to register with the DNS correctly would not register the FQDN and without that registration, stuff goes out, but nothing comes back. If you grab your IP, and do a NSLOOKUP on it from the command line, your should get something that looks like this:
Name: S01990005bbccddee.wp.shawcable.net
Address: 24.99.99.99
Theoretically it should return all the IP's. I haven't messed with multiple IP's on a single MAC address though.
(faked to protect the innocent)
The last 12 should match your MAC associated with that IP on your machine. Anything else and it won't work. If nothing comes back, won't work.
ARP -a might give you a hint about the other IP's, but somehow I don't think so.
If connected directly, take a look at the Motorola's status page. 192.168.1.1 or maybe 192.168.100.1 I think (Sorry I am too lazy to remove my router). There may be an error log that is of assistance.
I am really inclined to think it is a DNS issue though. The NSLookup will be a clue to that. Especially when you say 1 2 or 3 stop working. The last is still registered.
I am assuming that whoever you talked to at Shaw made sure you are getting the correct boot file. My experience has been (another cable ISP), that if you are getting a non traditional boot file (ie Static IP's), someone typically has to actually build the boot file, do the subnet, make sure the network IP is correct etc etc. I don't even know if Motorolas 5XXX can handle those custom config files (to be honest I doubt it). Most modems, once they have authenticated on the DHCP server, are given their IP and stuff, and told where the TFTP server is located and which generic boot file to ask for. Once that is done the PC makes it's DHCP call, the DHCP associates that with the modem, and resisters it with an IP from its pool (or if there was already an active lease it renews it).
Even an unregistered modem or when you forget to pay your bill will get a boot file. They just get a 'special' one that doesn't let them go to very many places, depending on the ISP. Sort of like when you don't pay your cell phone bill, but can still call the phone company or 911.
If you are using true Static, you would need something like the Motorola SBG XXX (Gateway = Modem and Router). When I built boot files for true Static IP's we were using Gateways, and actually uploaded the config / boot file from the WAN side. We would do this to replace the 'special' one that wouldn't let them do anything, and would bridge the devices that they configured for the Static IP's we would give them at that time. The IP's actually came from a different range compared to 'residential' customers.
I am inclined to think that Shaw uses what I think of as Sticky or Persistent ones (long lease) for residential customers. BTW if you do enable DHCP and it works you can discover the lease length with IPCONFIG /all.
When I look at Shaws packages. I don't even see a residential option for other than Dynamic. If you are a business customer you have to have the Server Connect Package to get more than 2 Static (as I read the packages). I am surprised that you would be calling into Tier 1 help. Normally business customers get a 'special' number for support. If you are a residential maybe you had a package that then no longer offer and didn't grandfather.
Oh one last thing. Shaw and other cable companies have been implementing the advances in DOCSIS. I remember in the beginning it was a propriatory network. Headend (CMTS) and modem spoke only their own language. Then came DOCSIS 1.0, 1.1, 2.0 and now DOCSIS 3.0 is being rolled out. What does this mean for you? Well maybe Shaw has implemented some new feature of DOCSIS.
Oh oh oh, one more last thing. Do you by chance also have the Digital Phone service and a second box? .... N'ah, forget that one. Makes no logical sense.
I go with the DNS registration and FQDN thing.
Ok so those are a few things off the top of my head. Man I talk toooooo much. |
