Hi folks - I'm trying to setup a C1113 as a modem by bridging the Ethernet0/2/0 and GigabitEthernet0/0/0 interfaces.
For the purposes of this exercise assume we're trying to initiate a PPPoE connection from a windows 10 laptop - at least that's the test setup. I have successfully achieved this on an old 887VA (config below), and i'm now trying to replicate on the C1113 (config also below) - which is working but the throughput on the C1113 is nowhere near what I expect.
I have a 80/20 VDSL circuit here in the UK, which uses VLAN 101 by the service provider.
On the 887VA I am getting 76Mbps throughput, but only 29Mbps on the C1113 - same circuit and same cable from the NTU to the router.
Any ideas why download through the C1113 is through the floor? Both configs work, I can dial the PPPoE connection in from a laptop, see my public IP on the laptop, and connectivity is working. I've switched between both routers a dozen times and the results are consistent.
To prove the C1113 is negotiating the correct VDSL speed as per the 887VA, I configured the C1113 as a typical router, and I can get 76Mbps through it no problem. In both cases on both routers I get 19Mbps upload which I expect.
Ultimately I will connect the C1113 to my ISR4331 with the dialer on the 4331 (to get the public IP's on the 4331) - Upgrading to G.Fast next week and there are no NIM modules to my knowledge which support G.Fast. Current NIM-VAB-A will be coming out of the 4331.
