D'Link Taipan DSL-4320L Slow on UFB

Hi All,

For the last few months I have been having a strange issue with my DSL4320L connected to fiber from MyRepublic. Nothing had changed between the time it was working correctly to when it started acting up. But I have been experiencing slow download speeds with the DSL4320L connected to the ONT.

I just wonder if there has been a setting I may have overlooked.

Ok, first up specs:

Router:

- D'Link DSL 4320L firmware AU_1.01.05Connection:- My Republic- Fiber 950/500 o WAN connection type - Automatic/Dynamic IP (DHCP) o On Automatic IP connection - Host Name and MAC Address fields blank o DNS Server Settings - Connect to DNS Server Automatically o VLAN - Untagged- Static IP

Cables:- All CAT6

Now the issue. All tests done over Ethernet on CAT6.

- I am getting approx. 200 down and 450 up when connected to the DSL 4320L- Connection seems to drop to 60/450 at night on DSL 4320L- 850/450 direct from ONT- 850/450 from provider supplied router- Only thing I haven't tested is speeds with using DSL 4320L as a bridge (ideally I don't want this to be the only way I can connect)

Things I have done:

- Turn off QoS on the DSL 4320L- Turn on IPv4 Multicast streams- Checked MTU (1500 while set to auto)- Disabled firewall on DSL 4320L- Rolled back firmware and re updated on DSL 4320L- Complete factory reset on DSL 4320L- Had D'Link support remote in and check settings- Completely replaced DSL 4320L!!!! (exchanged for a brand new one thinking it was a port issue)- Changed all cables- Restarted ONT- Cried in a corner- Yelled at DSL 4320L

Whatever I do I can't seem to get above 200 down on the DSL 4320L. I have a technician calling tonight but this has been going on since June so I don't have much hope that this will get resolved tonight.

If all else fails I will change provider but I am concerned that this might end up being an ongoing issue.

Any help is appreciated.
