Most of the latest Asus routers offer Dual WAN (including this one) but in you set up it sounds like you may be better off with a combined modem/router such as the DSL-AC68U (for VDSL) or the cheaper DSL-N55U (for ADSL) which for the expense would offer load balancing over DSL/LAN.

Following your point about the WA701's, I contacted TP-link and they suggested using two 2.4GHz 150Mbps Outdoor Wireless Access Point, seems to be a good idea. Cuts out the need for the WA701. Now just trying to work out how to combine the two internet connections in my house. Saw you can bridge two connections in windows, but I know the dual WAN / load balancing router would be a better option, just costs £150 minimum. Just going to check if adding a network card to my PC would be an option.

Thanks for your comments. In an ideal world I would use CAT6 cable, but unfortunately a main road prohibits this. I think I would be better using 24dB model antenna (TP-Link TL-ANT2424B) at one end and utilise the TL-ANT2414A that I already have mounted to the side of the house. I put together a quick picture. Do you think this setup would be better: ( The aim is to combine two fibre connections at my house into one for double internet speed when required )

It looks like your creating a point to point wireless bridge, so make sure you set the mode as such - not access point, that would not work. Also, ensure your router supports dual WAN / load balancing if your planning to share the internet connection. The main link in your set up are the WA701's, they're crucial so you may want to think about more powerful units. That said, there is no reason that shouldn't work especially if you are only needing ~80Mbps, depending on weather and interference from the outside world.

Regarding Genesis, it's unusable because it's now unsupported by the dev. Look at Specto which is a forked version with continuing development.

TP-Link equipment is fine, although at 100m you are pushing the limits of a "14dB" non amplified antenna. Might be a problem for HD streaming, but for internet access you should get signal. The last out building wireless set up I installed for a customer was a Linksys RE6500 (based on a MediaTek MT7602EN chip) and 2 DrayTek ANT-2510 antennas, which gave fairly good 150Mbps coverage at around 50m.
I would personally look at an external Cat6 cable run, which will give you a rock solid 1Gbps connection (depending on ethernet speed at each site) and have an access point at the remote site for wireless - a better set up, if its possible to do.

Hoping you could give me your opinion OUTRAGE. I'm extending a wireless network 100 metres from one house to another. Would your rate tp-link hardware to do a basic job? Would be using TP-Link TL-ANT2414A and tp-link TL-ANT2414b plugged into tp-link extenders.

Thanks. I think maybe ditching Sky will be the likeliest option. Just a few months before the contract ends.....
outrage
29 Feb 16#70
In that case, your Sky Hub is correctly on a different subnet, NAT Loopback 'is' working, just not how you want it because you have a double NAT - 2 private networks.
The best solution here for your network - although it involves spending money - is to buy a DrayTek Vigor 120 (for ADSL) ~£35 ebay, or a DrayTek Vigor 130 - ~£70 ebay (for ADSL and VDSL, in case you will ever need compatibility with fibre broadband). This is an excellent, reliable external DSL modem, and I have used it for customers many times for problems just like this. You would need to extract your Sky broadband username and password from the SR102 using wireshark (simple to do) first. This would remove the SR102 and double NAT altogether and everything would be handled by the Asus, as you are wanting.
It is a shame Sky force you to use their own equipment, but I would personally seriously consider an external modem if you are planning on staying with Sky or even moving to another ISP that doesn't allow their routers to be used as a modem only.

CORRECTION - the Asus WAN address is 192.168.2.7 (not 192.168.1.7)
itm2
29 Feb 16#68
Thanks for the feedback. Yes it's the Sky SR102, on ADSL (Sky Broadband Unlimited). Wireless and DHCP are turned off on the SR102, and Asus is set as the DMZ. Access to my internal servers works fine over 3G, port forwarding is all working correctly. The SR102 is on 192.168.2.1, and the rest of the LAN (including the Asus router) is on 192.168.1.*. The Asus WAN address is 192.168.1.7.
I'm struggling to get my head around option 1 (static route to bridge the two LANs). Would that allow me to keep the Asus as the DHCP server? Where/how would the static route need to be defined?
I'm not drawn to Option 2 as I didn't want to throw any more cash at it, and might decide do ditch Sky anyway when the contract is up in a few months.
Re. Option 3 - I understand that it's not possible to configure the SR102 in bridged mode, due to Sky insisting on locking it down presumably.
Option 4 isn't what I want, as it would negate the whole point of buying the Asus in the first place.
At this point it looks like ditching Sky may be the best option - unless Option 1 can help???

29 Feb 16#67
It sounds like youve got a double NAT. What brand / model is the "Sky router"? Are you using ADSL or VDSL (broadband or so called fibre broadband?) I happily moved away from Sky a year or two ago, but I'll assume you will be using a so called SR102 Sky Hub? If so, I again assume you have turned wireless and the dhcp off, and tried to add the Asus to DMZ to forward everything, this wont work for WAN to (Asus) LAN. The modem (ie your Sky Hub) has to be on a different subnet to your LAN.
What is the WAN address that the Asus is getting? Is it a private IP or your Sky WAN IP? As i believe this has no option to operate as DSL modem, you (unwillingly) have 2 routers / gateways on your network - not a good practice for your small home network.
NAT Loopback sounds to be working correctly on the Asus;
LAN requests WAN address -> resolved as WAN address on the Asus (which is the Sky Hub as a gateway) -> Forwards requests to Sky Hub -> Opens web config page of Sky Hub.
WAN requests from Android -> no local clients on the Sky Hub gateway subnet -> failed connection.
You've got a few options - as i say im not a Sky broadband customer so im not sure what their equipment is or can do;
1 - Change the subnet of the Sky Hub (or Asus) to a different one and add a static route to bridge your two LAN's.
2 - Get a DSL modem and remove the Sky Hub altogether (maybe an Openreach modem can work if you obtain the user name and password from the SR102 - I set this up for a friend on ADSL, not sure about VDSL?)
3 - Try configure the WAN connection in the Asus as bridged rather than DHCP (if the SR102 supports it). You might need your Sky DSL username and password and to use DD-WRT on the Asus for this.
4 - Use the Sky Hub as the gateway / router as Sky force you to (dealing with DHCP, routing, firewall, port forwarding, static routes etc) and use the Asus in Access Point mode to deal with Wireless and Gigabit switching only.
4 - Leave Sky and join Plusnet or Virgin Media who happily allow you set things up how you want (Openreach or Docsis modem to your own router).

I can ping using the WAN address from a Windows 7 PC on the LAN, but if I try to access my IP cameras from an Android phone using the WAN address the connection fails (it was working before I introduced the Asus router to my infrastructure).
If I try to access a web site on my server from another PC on the LAN I get directed to the console page of the Sky router. The Sky Router is connected to the WAN port of the Asus router, with the Asus designated as the DMZ on the Sky router. The Asus is my DHCP server and gateway.

It's more about being able to monitor folks Internet usage so they can then look to (more effectively) block said streaming sites.
I agree - I don't think end users of streaming will be prosecuted.
But if enough of the streams can be throttled/end up being more hassle than they're worth then that'll be a win in Murdoch's book.
Genesis (a popular streaming app via Kodi) is pretty much unusable these days for instance.

From what I'm told by the (many) folks I know who work for SKY and various other Murdoch media outlets, it's being sold to the public as being about protecting us from paedos and terrorists.

I have an RT-AC68U and nobody seems to have managed to get NAT Loopback working on it, even with the latest Merlin firmware. So you can't access URL's hosted internally using the public domain address. If this is an issue for anyone you might want to check the situation with the RT-AC87U before taking the plunge.

Did you read the powers the bill would introduce?
"allow police and intelligence officers to see the Internet connection records, as part of a targeted and filtered investigation, without a warrant"
The bill doesn't stop at paedos and terrorists. They can use it to investigate whatever they like.
For example I'm a medical doctor (emergency physician). I've seen and heard all sorts. You might spend all day on hotukdeals and ebay... I routinely deal with and look up information on illicit drugs, weapons, poisons, human trafficking etc.
(Yes I know doctors are mentioned in the draft bill, but it just acknowledges that there may be potentially sensitive information due to certain professions and then says they can get a warrant to use the data anyway if they fancy).
So I'll keep my VPN thanks :smile: and no that still doesn't mean I'm up to no good.

1ghz cpu in this... Would prefer a Linksys WRT1200AC (advertised at 1.3ghz but actually 1.6ghz) which is compatible in price. I have all my traffic going through a VPN which is very CPU heavy. One of these would top out around 27mbit while the Linksys would top out my bt infinity and Max around 40mbit.
I currently have a piddly 720mhz tp-link which can only manage around 18mbit which is a little bit sad :disappointed: that's the price you pay for security I guess?

Host file isn't an option as some of the client devices are Android (e.g. I want to view my IP cameras from inside and outside the home). Setting up a DNS server seems like a major undertaking for what should be a trivial thing for the router to do.

I recently got an Archer C7 (from, as it happens, an in store deal in Currys/PCWorld) which stopped working until power cycled a couple of times. Googling, it seems other people have had similar problems. Now wondering whether to take it back, or try DD-WRT on it.

Bought one last week and had nothing but problems with it. Whilst signal is stronger than the BT home hub, its only marginal. I've tested it with 10 devices over various distances. My internet speed at the router has dropped from 70Mbps on BT HH5 to 65 Mbps on the Asus. It has locked up and stopped working for no reason. On one PC with a previously rock solid ac wifi adapter it not only causes the adapter to lock up, but also crashes the PC with the following blue screen "Kernel Security Check failure". I've updated the Asus firmware and also tried Merlin. I have spent many hours trying different channel setups etc. I like the VPN setup, the network wide security and traffic monitoring, but think I'm going to give up on it. It's cheaper than more basic Asus routers for a reason. I had the TP Link Archer C7 which was rock solid.
