Setup instructions for Airave behind a router


Re: Setup instructions for Airave behind a router

When setting up an Airave, putting it behind the router works just as well as having it before the router.

Unless you have a dual modem/router combo there is usually no issues or additional steps needed.

1. Make sure Airave is off.

2. Connect ethernet from WAN in Airave to LAN/ETHERNET/#'d port in router.

3. Turn on Airave.

4. If broadband light comes on within the first 5 mins then you are good to go for the broadband connection.

Do not log into your Airave's interface unless you are trying to create a static IP for it.

If you make changes to the Airave UI, a hard reset clears any changes. Powercycle instead.


Re: Setup instructions for Airave behind a router

Thank you for your input.  Keep in mind that although many Airave owners use the reversed style of hookup, we still prefer the Airave be connected directly to the modem.  This is primarily due to the Airave having to compete with a customer's wifi traffic when hooked into the router.  When the Airave is connected before the router as in modem/airave/router, the Airave gets the most consistent flow of data and is less prone to failures.

Re: Setup instructions for Airave behind a router

So I have been using the Airave successfully behind my router for the past year and then we recently got the Time Capsule for our computer which also has a built in router. So we got rid of the old router and now I am having a ton of issues especially with the Airave. I can't seem to get it to work behind the router, in front of the router, I've reset the Airave, still nothing. I've read the threads on how to reset the IP address on the Airave and doing all those other things, however, I am not very skilled with these things and am looking to see if anyone else is using the Time Capsule as their router and how they are able to get the Airave to work.


Re: Setup instructions for Airave behind a router

I used an Airave behind my routerfor over a year, never had an issue.  Recently however I have noticed the airave acting up.  All lights on the airave are solid green meaning airave should be working, however, when I look at my phone it clearly is not by the 0-1 bar signal.  Dialing *99 confirms, airave is not up.  Pull up my router LAN listing and airave does not show up.  So for me everything appears to be working as indicated by the 3 solid green lights, but its almost like the airave gets dropped by the router. 

I've called airave support, fixed for a week, then same thing happens.  Today I tried these steps, just got flashing amber mobile light.  Gave up, did a factory reset, now everything is working okay so far.  Called Sprint again, they are sending out a new airave.

We shall see.  Keeping my fingers crossed that network vision begins in ly area this winter like it has been rumored.


Re: Setup instructions for Airave behind a router

It was really easy to set up the Airave 2.5 after I stopped listening to all the recommendations.

After I finally got it reset, the only changes I made were to my router.

First I setup a static lease address for the Airave in my router’s DHCP server using the Airaves MAC address.

Then I setup UDP ports 5060 and 5061 to be forwarded to the Airave, plugged it in and it was working in about 5 minutes.

Piece of cake.


Re: Setup instructions for Airave behind a router

I wonder if using this setup I can put my airave between my router and a b*tchy switch I have in the other room. Will it still pass through with the lan port, which is all I need? I constantly have to reboot that switch to make a call now, having it just plugged in downstream of that switch with it's default factory settings.

Edit It sure would be nice if this sprint community had "search this thread".

What about the blocked ICMP messages from my airave IP address on my router?


Re: Setup instructions for Airave behind a router

Thanks to everyone who have posted on this thread. It was helpful troubleshooting my own problems after reading all the issues and problems people were having with their airave.

FYI, I have an Airave 2.0, configured behind a TP-Link WDR-4300 dual-band router. I have tried all the methods mentioned throughout the thread (assigning static IP, opening ports, using DMZ) and have observed the following:

The three lights on the Airave will stay solid green and I'm able to make a call. However, approximately 1-2 minutes into the call, I would lose audio on the other side. The call does not disconnect and the signal on the phone still shows excellent coverage. When I try to call again, my phone will not connect and I do not hear the Airave 3 beep. My phone shows that calls cannot be completed. After a few hours, the dreaded flashing amber mobile light appears on the Airave.

I have called Airave support and ask if my Airave MAC is registered and they said yes.

I have tried hard reset and configure it without assigning static IP, opening ports, or using DMZ but still same result.

Has any one seen this behavior with their Airave experience?

Any advise or tips would be greatly appreciated!


Re: Setup instructions for Airave behind a router

Same thing happens to me once or twice a month.  The other party can hear me, but I can't hear them.  I have to power down modem-router-airave, then power up and that will fix the problem.

When the Airave works, it's great.  When it doesn't, it's a pain.

This is an annoyance for which it would be nice to see a fix!

Re: Setup instructions for Airave behind a router

Did the airave ever do this while connected directly to the modem? Did you happen to run a line quality test while this was happening to see if it may be related to your internet connection?


Re: Setup instructions for Airave behind a router

I just recently got the airave from Sprint, immediately it fixed my lack of cell signal here at home.  Everything seemed to be humming along fine, then I realized that there was trouble getting youtube videos to play.  Did a bit of searching and found the instructions to setup the Airave behind my router took a bit of doing but got it setup and all seems good now. 
The question is there a down side to doing this?
