I recently changed my plan to Shaw 150 and got the new Arris comcast modem this morning. Only after 3-4 hours, I noticed huge lag spikes in games and streaming. I looked up Shaw forums and noticed tons of posts on this buggy chipset used in most of Shaw's modems.
I just wonder if Shaw ever investigates these issues before making the purchase? but I guess this is what happens when a bunch of marketing guys with tier online MBAs run the show fighting over saving pennies. After two years of being a Shaw customer, I feel that there is no end to Shaw's F#@$ ups and their customer always gets the bottom of barrel hardware.
My modem:
Model:TG3482G
Vendor:ARRIS Group, Inc.
Hardware Revision:11
Not a Shaw employee-but my tests with the XB6 have been very good and the XB6 has a Puma 7 chipset.
The Hitron CGNM-2250 and Cisco DPC3825 are Puma 6.
The Puma 7 does still have some issues-but this looks much worse (also note those tests can also vary based on your browser even!)
It could be a bad coax cable in this case? Have you spoken with support? That looks like signal issues if it is that bad.
