Well - I know there are a lot of bridge mode questions out there, but none have helped me so far, and I really can't figure this out. I'm trying to get my C2100T modem in bridge mode. I have this modem as I did a trial of Prism TV, but cancelled it after a week, and just kept the internet service. The C2100T is a decent router - it is a 400MHz dual-core AC router - best router I've ever had from an ISP. However, I have 25-30 devices hooked up, and it can bog down. Another issue (a big one for me) is that it ignores custom DNS servers. No matter what I do, it always puts the routers IP as the DNS server ahead of the ones I want. Centurylink is no help with this. I have a Nighthawk R7000 that is more than twice as fast, the DNS servers work, and it has other features I use, like file-vault. So yeah - the C2100T is a pretty decent router by ISP standards, but not what i prefer to use.
My service uses IPoE, and not PPoE. I've heard that you need to get your PPoE username and password to use your own router, so i got this from centurylink. However when I try to set the C2100T to PPoE, and use the username and password, it doesn't connect. If I switch it back to iPoE it will connect right away. So either the username and password they gave me is wrong, is there is some other issue. I've heard others say you don't need a username and password if you have IPoE. Maybe I need to clone my modems MAC?
Other specs in case they are useful
ISP: IPoE
Broadband Mode: VDSL2 - 8A
Transport Mode: PTM
Path Parameter: 201
Service Type: PTM - Tagged (201)
MTU SIze: 1492
MSS Size: 1452
RWIN Size 58089
The modem has a few different options for bridge mode - I've tried them all, along with setting VLAN tagging on my Nighthawk. Nothing has worked. My bridging options are:
Tagged-201
Tagged-0
Untagged
What I thought would work would be to use Tagged-201, and then set my Nighthawk to use VLan tagging, set to 201. That didn't work, but could be because my PPoE username and password might not be working. Should I first get the modem working with a PPoE username and password before trying any other router? Or stick with IPoE?
The username and password CL gave me was myName@qwest.net, while when my modem is working with iPoE, it's has a Centurylink username, with a password I cannot access.
At this point I'm really at a loss. I ordered a managed switch, and I'm going to try to use that to strip out the VLAN tagging next, and see it that gets me anywhere.
If anyone has been able to bridge their router with a situation similar to mine, any advice would be greatly appreciated. I'm wondering if I should just get a simpler modem, just so its easier to put into bridge mode.
