How to Super Extend Range of your Android WiFi Hotspot using DD-WRT!

The other day my Comcast Business internet went down again, that’s the 5th time it happened and my download speeds crawled to around 1Mbps download for couple days (while I paid around $200/month for 100Mbps).  On those days, I usually tether my main office computer to my Verizon Note 3, which I have an unlimited grandfathered plan.

Now, in most cases you can easily tether off your phone without a problem if you get good download speeds everywhere in your house.  Well, in my case, the best download speeds for Verizon 4G LTE is actually in my outdoor tent.  But if I put my phone there, I can’t tether that well from everywhere within my house because there are walls and other things blocking the signal.

So, how do you extend your WiFi hotspot signals so you can use it everywhere in your house?

The answer is rather simple, you can use a WiFi repeater.  A WiFi repeater, as its name implies, simply “repeats” wireless signals.  Now, you can buy these WiFi repeaters on Amazon but the problem is that they don’t work that well, the range is pretty bad.  A better way to approach this is to make your own custom DD-WRT router and put it into repeater mode.  This way, you can hack the router and increase the transmission levels just the way you want it.

I had a bunch of old Linksys E1200s lying around so I decided to recycle them into an Android WiFi repeater.  These are actually much cheaper than buying WiFi repeaters so you get better repeaters and save money at the same time.

You can also use any type of routers that support DD-WRT firmware (you can check it your old router is supported here).  Also do make sure the router you want to use as repeater supports the type of wireless you want to repeat such as Wireless-N, Wireless-G, etc…etc..  The E1200s are great because they support both N and G.

    Thanks for the kickass tutorial. I’ve followed this twice successfully; however I can’t seem to figure out why the network is unprotected. I also can’t figure out how to access the admin once I’ve applied the settings. For instance, I did this the first time and realized there was no password. I had to do a 30/30/30 in order to access the admin to run this tutorial again. Once complete; no password again. Any ideas?

      I revisited this the other night and cannot manage to get security to stick. My network is wide open even though I’ve followed the tutorial to a T. Are there any forums I could try for help? I have no experience with router software

    Two things you forgot to mention. The router must be first set to the same WiFi channel as the hotspot. The problem is some phones are set to auto and you can’t change this. The phone will switch channels if the channel it’s on gets too crowded. The router itself can cause the phone to switch channels, so router should be switched on after the phone hotspot is switched on.

    Second point, the gateway address must be set. This should be the IP address of the hotspot. Otherwise there will be no internet.

      David, any chance you could weigh in on my situation below where I commented that my repeater is wide open and not password protected? I could really use the help! Thanks for any help!

        Greg, so in the wireless security tab you select the security mode ‘WPA2 Personal’ for example. WPS Algorithm AES. And then put a password in the WPA Shared Key field. Then hit ‘apply settings ‘. It should be that simple.
