Help.

I have a Slingshot unlimited account and two modems.

1. Modem one is a TP Link TD-8840 and runs great. VPN works a treat and it gets DL rate of about 6Mbps. Quite happy with it but

2. I have a Huawei MT882 that achieves DL rate of 12-15 Mbps. So, it's faster but:

The TP Link won't connect with ADSL2 or ADSL2+ only g.dmt (hence the lower rate?)
The Huawei connects as g.dmt.bisplus but won't allow VPN (the VPN crashes within 30 seconds of use every time). Internet connection is fine. I need VPN for work.

The VPN machine is running Leopard 10.5.8 and connects via pppd with standard OSX PPTP.

Any thoughts on how to make the TP Link connect at ADSL2+ rate? Or get the MT882 to allow VPN?

I have tried numerous combinations of settings and bridging and MTU and Firewalls and Port Forwarding. With respect, I don't need any more random guesses, I need someone who knows these devices and can comment on the problem as described. Falling this, I need to know if the the Vigor 120 will connect at ADSL2+ rates so I can buy one of those or similar. I really like the TP Link box, it is very stable but obviously I want to achieve the higher speeds if I can.  

More info: The modem connects to an Airport Extreme and onto iPad, phones, two Airport machines, and ethernet to G5 and PS3

I connect to a cabinet that is 20 metres from my house. I live in Rotorua. Urban. Isolation test done.

Thanks in advance for your input and advice.

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?
