Loss of bandwidth ... What should I check please?

DaneA,

Thank you for replying. I do appreciate it! Thank you for the warm welcome, too!

[Q] Is the SRX5308 connected to a modem-only device or to a modem-router provided by Xfinity Blast?

[A] The SRX5308 is connected directly to a ARRIS SURFboard SVG2482AC Eth Port 1. 

[Q] I suggest you to set the modem-router to full-bridge mode so that it will be a modem-only device

[A] I see on the "At a glance" web page that Bridge Mode = Disabled. Is this what you are referring to?

 When I click the enable button, this pops up:  "Enabling Bridge Mode will disable Router functionality of gateway and turn off the private Wi-Fi network. Are you sure you want to continue?" I have the wireless disabled at this time, so I dont know if this is a big deal or not. Also, I have phone service connected to this device. Will this be impacted if I enable this option? Thoughts? 

[Q] Since you have upgraded the firmware of the SRX5308 to v4.3.5.3, did you perform a factory reset after upgrading the firmware? 

[A] I did not. Is there a preferred link I should look at for instructions on how to do this?

I am assuming the following:

Backup / Restore Settings

1) Save a copy of current settings

2) Revert to factory default settings. Click the "Button". I will need to find out the default name/password. 

3) Restore saved settings from file

Yes? I have some LAN/WAN Rules too... anything special I need to do regarding those?

Thank you again!!
