Hi both, I am having the same issue with my RT-N56U too. I am on Time Home Fibre and I have a DynDNS hostname tied to my dynamic IP. I can access my Download Master web app from outside my home network, but connecting to the VPN server has never been successful. I have tried to initiate a PPTP connection from my Win7 laptop, my iOS7 tablet and even my 4.4.2 Android phone - no joy.

However, previously I was on another firmware version, a newer version which was taken offline by Asus recently. When that firmware was active, my VPN server was ok.

Current firmware (problem with VPN server feature) = 3.0.0.4.374.979
Previous latest firmware (VPN server feature OK) = 3.0.0.4.374.2078 (no longer on Asus Support website)

Home VPN : Time Fibre Home
Mobile : Maxis 3G, Streamyx, Digi 3G

The thing is, on the latest greatest firmware version which was taken offline by Asus, the VPN server functioned fine.

Oh, just replied your PM without seeing your request above. I can only send you my settings file tonight once I get home.

If you want, I can pass u a public dropbox link to the latest firmware FW_RT_N56U_30043742078.zip that is no longer available on Asus support web page. I managed to download and use it some weeks back.

Care to share the changes proposed and made?

Hmm, I don't have port forwarding enabled on my RT-N56U. Another issue at my end, I think.

Yes buddy, I do have DMZ enabled with my home PC's LAN IP address in it.

Have disabled DMZ, VPN server on the RT-N56U is now accessible from outside via Maxis 3G. Have not tested internet and home network access via VPN yet, a bit busy with work.

Yes, finally vpn server works. So dmz needs to be disabled for vpn server to work. I made 2 more changes though.

1. The vpn client ip pool 193.168.1.91-100, changed to same subnet as my home network 192.168.1.10-90

2. DNS server settings for vpn clients were manually configured to my UnoTelly DNS servers (paid service).

Both your 'client' and 'himedia' have N-300 wifi capability? From what I remember, a basic N-spec connection is usually 60-80 Mbps.

I remember having the same issues like you, previously, on my RT-N56U. Someone, I forget who, asked me to try disabling DMZ on my router. And after that my issues were fixed. You may want to try it.

Maybe you have a dud unit, buddy? I have been using an RT-N56U for almost 6 months now with zero issues - I have 2 laptops, 1 PC, an iPad3, an S2, a Note3 and 2 NAS boxes connected in my LAN, most of them over wireless with a few via Powerline Ethernet. You have tried factory reset and re-setup?

Guys and gals, I have a question. I was helping a friend of mine who had an RT-N66U at his home connected to his 8MB Streamyx line via a TM-provided dLink modem. He had been having trouble accessing web sites ever since he had his router installed. Last night, after updating the router's firmware (didn't help) and mucking about the settings of the router, I finally found that setting the MTU and MRU to 1480 (instead of 1492) under WAN section fixed his Internet access issues.

So now I am wondering if I should do the same on my RT-N56U connected to a 15MB Time Fibre link?

Yes, based on my experience 1492 is optimal for PPPoE. I had factory resetted his RT-N66U and also flashed up to latest firmware, but these didn't help until I brought down the MTU and MRU to 1480.

Perhaps I will drop by my friend's place to test some more, using the info in this article - http://goo.gl/0uURiN.

I have a friend on Streamyx 8MB link with similar issues with upload speed when using his RT-N66U router. After testing a bit and playing around with the MTU and MRU settings on his router, his connection is ok now.

Used info from this article when I helped him troubleshoot - http://goo.gl/DHNahz. BTW, the most optimal setting for him was 1452 (1453 and above causes error) so I had set 1480 (i.e. 1452+28 as per article) and he's a happy camper now.

For my home Time Fibre connection, the same value worked best too. Not sure if this is related to your issue, but may not hurt to try, eh?

OK sure. If it's any consolation, I have 2 other friends using Asus routers. All having no speed issues other than the usual complaint of internet speed not being enough

1. Asus RT-AC66U with Unifi 10mb = no problems
2. Asus RT-N66U with Streamyx 8mb = no problems
3. Asus RT-N56U with Time Fibre 15mb = no problems

Perhaps there is a modem vs router compatibility at play or some settings issue, here..

I think the price difference between AC66U and N66U is small enough that going for the AC model is probably my best suggestion. Personally, I am more interested in the dual core, dual band AC68U model

If I remember correctly, in 2.4ghz spectrum both channels 8 and 11 do have overlap. Only channels 1, 6 and 11 do not overlap.

I have a buddy living in a 3+ floor home. '+' meaning he has an open area to hang clothes and also to sit and lounge around at night, on the roof top.

He has an AC68U on the ground floor with his older N66U on the 2nd floor acting as an AP (connected via ethernet cable to the AC68U). Coverage is good everywhere in his home. 1 SSID each per router with an additional guest SSID on the AC68U.

I remember he mentioned with just the AC68U, the signal was very poor on the 2nd floor and totally unavailable on the rooftop floor.

BTW, my friend did not use a powerline connection between the AC68U and N66U because he already had gigabit wired networking set up in his home during renovation.
