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 but2. 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 PS3The MT882: Ping 33msADSL State Show TimeData PathInterleavedOperation ModeG.dmt.bisplusMax.
