Hello guys,

I’ve been reading this forum and this is the 1st time I’m posting here for a solution.
1st you can look at my attached network map below which I described in details. I did this total networking for my office by myself or under my guideline. In this area the internet form the ISP if not very stable and it gets down frequently, sometime link problem etc. So I always need another Internet as a backup. The primary is in use all the time. And my few optional as backups are a wireline based ISP, 3G USB dongles, Android Mobile USB/Wifi theater etc.

According to the Network map, here is the complete details bellow:
# Nanostation Loco M5 (5GHz) router > takes internet from the ISP Tower and provide in to my main router’s WAN.
# My main Router iball baton (iB-WRX150N) 150N router (Indian Brand): it is the one which takes the internet and it control all other PCS over LAN (DHCP, IP Assign to other PCs, Bandwidth Control, Access restriction etc)
# Switch1 attached to this router LAN port which connected to my Admin PC only.
# Switch2 attached to Switch1 and it connects all other PCs over the LAN.

Now I need internet connection all time running for my office so whenever I see any issues with the internet link or completely down I shift to a backup one. Now the problem is if I shift to any backup one I have to change the WAN IP in my (DHCP) based primary router.
So this is what I’m doing now to change the internet,
Option 1: I have another wireline ISP connection, I put that cable into Main router’s WAN (by replacing the Nanostation) and change the WAN IP in router. And all get online. But this doubles the internet cost (Two ISP) also I have to change cables, IPs which took time.

Option 2: I use the PC 1 (it’s the admin PC) and when the internet is down I put a 3G USB dongles or Mobile USB theater, change the IP in my PCs LAN IPv4 like a router (192.168.2.1) same for all IP, gateway, DNS etc and put the LAN cable to Router’s WAN port and change the Router’s WAN IP. This way all the PCs get backup internet over LAN but I lost the connection/control to all PCs over LAN, as I view their screen all time. So this is just cost effective as I have internet in my mobile but this also takes time to configure all.

So I was wondering to get a hassle free solution where I could quickly bring the backup one online.

Here are my ideas which would make this reliable:

1) For me the best solution is: I sometime login into Nanostation and change the ISP provider’s tower if any issue with the connected tower. The same way I was thinking if I turn on the Android Mobile Wifi theater and could connect with the Nanostation that would be great. No IP changes require and no hardware cable change require also I’ve full control as earlier. But the Nanostation Scan cant find the Mobile Wifi theater Hotspot SSID. My mobile is Galaxy Note 3 which says Dual band (2.4Ghz and 5Ghz) but this isn’t working. So any input on this possibilities?

2) my other thinking was, my primary router have WDS option, so if I could connect my mobile Hotspot by WSD and could share internet over LAN that would be great also. But in this case I can scan my phone hotspot by WDS and I can connect it from the router, all ok its fetching phone’s MAC address etc but on the phone its not showing connected with any device also no luck over LAN.

3) Another option is a 3G Router: a usb dongle attached all time with the primary router but that would be cost effective too. I’ve to get a new router also a separate mobile bill for the USB dongle, as I have to keep my phone internet as well.

So if you guys have any advice on this please share, I can get any additional device to make this work but I prefer a way over wireless with my phone where I don’t have to change any IP, hardware and quickly I can shift the internet.

Thanks in advance!

The simplest solution as you suspected is to buy a router that supports wireless dongles as a backup like the tplink or asus. If your wireless broadband on your phone is SIM based (ie it is not cdma) you should only be only looking at a one time cost for the dongle you would move the sim from your phone to the dongle for the actual service.

The reason you can not get the router to connect to the phone via WDS is WDS is not a standard and the phone likely does not support it in the first place. WDS is used to solve the issue of multiple mac addresses needing to share a single encrypted wireless link . Since the mac address is used to determine the encryption keys you can't have different mac addresses.

So what you need to so is in effect let the router have its wan interface be wireless so only its mac is seen and it hides all the other machine via nat. This is not a common feature even in repeaters much less a router. You would be looking for a client-bridge/routed function. The name varies.

The cheapest way is to buy a actual client-bridge and hook it to the wan port of the router. The ones used for tv or game consoles that have only a ethernet port tend to be the best and cheapest. They do not run WDS they only allow a single mac which will connect to any hotspot/router. Many times these are sold under the name gaming adapter

The nanostation loco...is actually a fancy client-bride. If you were to get the 2.4g version it would likely do what you need but it is directional device so you would have to take that into consideration. They tend to be a little complex to setup since they have so many options. I think they are about $50

Thanks a lot for your advice, yes USB Dongle Router would be the simplest way and I’ve many dongles too. for this the only issue is I’ve to run a extra dataplan for that all time, as I cant take off my primary phones sim into that also I cant stop my phone datapack, as internet always runs on my phone even when my PC is off. Also I can get good USB Dongle Router at cheap cost here, so no issues.

I also read about WDS and found that is not possible, also thanks for your more detailed information.

Also I looked over shops here but didn’t see any good client-bridge Router, few were there but those are way too expensive.

The Nanostation M5 is good and I like its all features but somehow it cant fetch my Mobile’s Hotspot.

That is because the M5 means it is running on the 5g band you would need the version that runs on the 2.4g band. If you can't get ubiquiti stuff engenius also sells outdoor bridge equipment..they sell indoor stuff too but I have never used it. Something like ens200 is about $60 in the US.

Yes but my Samsung Galaxy Note 3 Specification says Dual Band (2.4GHz and 5GHz), that is why i tried it. but don’t know how it says, it neither scan 5GHz SSID and the Nanostation cant see it as well.

Ok I will look for that stuff too.

Another way I was thinking is: as only 5-6 PCs runs over my LAN and if I put USB wifi adepter for all then all PCs easily could connect with my mobile Hotspot easily when internet is down. That will be also atomization, if I turn on hotspot, wifi enabled and allowed PC will automatically get connected. Also as the wired LAN will be active I would still have the control over all those LAN PCs. I can get 5-6 USB wifi adepter at the same cost of a USB Dongle Router.

No, if I turn off the mobile hotspot all PCs will be disconnected from the wifi network. Even I've tried that with a Lapop connected with LAN and WIFI as well. The only issue will be I won’t have any control for bandwidth restriction and access restriction etc. But that’s fine for a temporarily connection. Also if I increase LAN PCs in future that will be difficult as the mobile hotspot only allows 10 device connected at a time. So its not reliable way for future as well.

But I will do this if no other way works. Thanks for your all advices.

Hi there,
I’m able to setup wifi with adepter for all pcs and testing with one and this looks like the easiest solution for me. But one issue I’m getting which I cant solve.

When all PC are already connected through Ethernet and when I turn on wifi and get connected it cannot get internet from the WIFI, either I have to disable and enable LAN and then it works fine. But I don’t want to do that as I keep the LAN PC screen share all time. Also it’s a manual process.
I tried everything, Interface Metric set to give the WAN priority over LAN, Binding menu, but its working automatically very few time. I was wondering when LAN is active and if WLAN connected it will shift internet to the WLAN. But no way this is working.

Any tricks or software to make this atomization?
