What region are you located? - USA
Are you wired or wireless connected to the router? - Wired
Was a Factory Reset performed before and after any firmware updates then set up from scratch? - No, but I've never touched the settings, since I know next to nothing about networking I try to keep my hands off that stuff to avoid making things worse and everything's always just worked till the firmware upgrade. Have the factory defaults changed from 2.00 to 2.11? Could that be whats happening since I'm still using the defaults? I'll give that a shot and try to find a reset factory defaults button in the router web gui after this post.
What ISP Service do you have? Cable or DSL? - Bright House, Cable.
What ISP Modem Mfr. and model # do you have? SurfBoard SB6141
Is ISP Modem/Service using Dynamic or Static WAN IP addressing? Uh... no idea
What ISP Modem service link speeds UP and Down do you have? 70 MBpS Down / 6 MBpS Up
I want to hold off on making any router configuration changes if possible, because, again, I know nothing about this stuff. I honestly felt uncomfortable just upgrading the firmware, but if you are certain these things you're asking me to do have become necessary with the new firmware to get your full download rate, I will try them. I'd rather flash back to a firmware that doesn't need me to touch the configuration, though, if that's an option since again, I had no issues with 2.00 and my download rate. Thank you for posting in response though, I appreciate it.
