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_1.01.05
Connection:
• 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.

Changing provider is not going to fix it - you state you are getting 850/450 with t he provider's router (and direct from ONT) - therefore the problem is the Dlink - changing provider is not going to fix it.

Have you tested it over LAN with a different PC/Laptop?

Thanks for the reply.

I had a feeling that changing providers would not be the fix. I did speak with D'Link and after they ran some tests I sent it back RMA. Went to JB Hi Fi and did a swap so it is a brand new DSL4320 in at the moment.

The results from the tests were done from a PC at home, other tests done on a laptop had the same result. I ran some WiFi tests as well in case it was a port issue but sadly got the same result (slow download but fast upload)

As above the issue is not your ISP so no idea why you think changing providers is going to help

Edit: Why don't you just use the ISP provided AP? Clearly it's doing a better job than the D-Link

Agreed, it doesn't seem to be a provider issue.

In terms of using the provider router and the DLink as an AP that is an option, however more of a last resort. When you spend $500+ on a router you would hope it works as expected. Its just strange that it was working fine for around a year with the DLink connected to the ONT then all of a sudden it doesn't.

Is this a known issue with DLink as I cant seem to find any resource?

I've said this many times and will say it again - just because it is expensive doesn't mean it is good. The Taipan routers are quite buggy and frankly terrible, they do struggle with gigabit connections.

Take it back, get your money back, and go with a proper solution like the Grandstream GWN7000 ($212.75 incl) and a Grandstream GWN7610 ($224.25). Also don't forget to buy a PoE injector ($33.35). This comes to a grand total of $470.35 and is much more capable (and will give better WiFi) than the Dlink, it also can route Gigabit totally fine.

Consumer grade routers can be a complete ripoff.

So MyRepublic have just advised me that they do not support the DSL-4320L and it is basically useless on their network.

Thanks for all your help guys.

Will be looking at some replacement routers.

I mentioned one above else I've got a thread with router recommendations in my signature.

Either that or the Ubiquiti AmpliFi if you're looking at that price range and want good WiFi. Else, if you're wanting just a router that gets you online at Gigabit speeds then use their provided router or the Huawei HG659. Don't get sucked in to expensive consumer grade routers, they're all rubbish (trust me - I've tested many of them).

It's not that it's "basically useless on their network" it's simply that they don't provide any support.

Like any RSP they provide basic instructions on configuring any 3rd party router on their network. Most RSP's will however provide no (or very limited) technical support for 3rd party routers simply because they have no control over these.

If you want a supported device you'll need to buy something from them.
