OBiwifi Wireless Adapter

[Mack002]

1) I could connect using the Obiwifi wireless adapter and an Obihai 202 to callcentric.com and make and receive calls using firmware 3.0.1 build 4303.

2) I upgraded to firmware 3.0.1 build 4330 because callcentric recommended doing so.

3) Now I can no longer make calls using callcentric.  I sent callcentric screen shots of my Obihai 202 configuration pages, and they said that the configuration was fine and recommended that I connect through a wired internet connection.

4) Why does the Obiwifi wireless adapter no longer work and what can i do about it?  Would downgrading to build 4303 fix it?

Thanks; all suggestions appreciated.

(I don't have an Obi202 nor an Obi Wifi.)

Are you receiving calls OK over WiFi with the 4330 build?

Does the wired connection work for making and receiving calls with the 4330 build.

If you want to know if the firmware downgrade will fix things, why not try it yourself?

I can neither make nor receive calls using wifi.  My callcentric account says that my device is not registered.

I don't have a wired connection now, so I do not know it the 4330 build works with a wired connection.

I'd like to revert to the 4303 build, but I don't know where to get the file.  Any suggestions?

Did you check the OBi's Wi-Fi connection after you did the upgrade?

What response do you get to dialling ***1 on the phone connected to the OBi?

I'm using a Verizon Jetpack model MHS291LVW for an internet connection; the Jetpack used to play well with the Obihai  (before the upgrade).  After the upgrade, the Obi took a long time to connect to the Jetpack, but eventually did.  The Jetpack shows it as a connected device, the power light on the Obi is solid green.  I can ping ping.callcentric.com from a computer connected to the same Jetpack.

When dialing ***1 the response gives me Obi's IP and states that DHCP is disabled.  The IP given by Obi and the IP the Jetpack says the Obi is using are the same.

Thanks.  I welcome further questions and ideas.

I found a way to connect to Callcentric and make calls using the Jetpack internet connection.

I unplugged the Obiwifi, power cycled the Obi, plugged an ethernet cable from my computer to the WAN on the Obi, setup internet connection sharing on the computer.  Then, the Obi registered with Callcentric and I can make and receive calls.

My hope is that Obi will find the glitch in the 4330 firmware that prevented the Obi from connecting wirelessly.  Just using the Obiwifi to connect is much easier - when it works.

Thanks for the questions and help.

I wouldn't try 4303.  This is a link to the most recent firmware I would consider trying as an alternative to 3-0-1-4330

3.0.1 (4269) for OBi2 & OBi3 Series: http://fw.obihai.com/OBi202-3-0-1-4269.fw

Personally I am still using  3.0.1 (4142).

It looks like the OP manually assigns IP addresses.  I would have checked that the OBi hadn't 'forgotten' the gateway and/or DNS server settings when the firmware was upgraded.

I'm the OP.  I've never used static IP addresses - especially with the Jetpack, it just passes the addresses to each device that signs on.  I guess the reference is to  my statement "When dialing ***1 the response gives me Obi's IP and states that DHCP is disabled.".  I found the fact that DHCP was disabled odd as well.

When I connected the Obi to my computer via an ethernet cable to share internet access (from the Jetpack connected to that computer) the Obi connected immediately using that shared internet access without any issues.  I did not changed any Obi settings; I just unplugged the ObiWifi and plugged in the ethernet from my computer.

[drgeoff]

In which case I would definitely point a web browser at the OBi's local IP address and have a good look at the network config settings.

It used to be an unwritten rule that immediately following a firmware upgrade any device should be reset to factory defaults and re-configured.  Most times you will get away without that hassle .....

[Mack002]

When I look at the Obi network configuration settings, could you tell me what I should be looking for?

When you dial ***1 your OBi is telling you that DHCP is disabled which means it isn't automatically getting valid IP address settings from your router.  While it is possible that whatever IP address the device does have is within the subnet range of the router there could be problems such as:

1.  It has the same IP address as another device on your network.

2.  The gateway address isn't that of your router.  Symptoms are that you'd be able to communicate between the OBi and other devices on your LAN but the OBi would not communicate with anything on the WAN.

3.  The DNS server address might not be pointing to a DNS server.  (Typically your router).  Symptoms again are that the OBi cannot communicate with named sites/servers on the WAN because it doesn't get the IP numbers of those sites/servers.

Almost always the router address (which you need to put in the OBi gateway and DNS server fields if DHCP is not enabled) ends with 1 or 254.  Check with the router documentation if necessary.

Probably easier just to enable DHCP

Today I got a wired (DSL) internet connection.  Obi works well.  On dialing ***1, it gives the IP address and says DHCP is ENabled.  Recall that DHCP was DISabled using the ObiWifi. I made no setting changes to the Obi.  Is it correct behavior for the Obi to have DHCP  ENabled using an ethernet connection and DISabled when using OBiwifi - without settings changes?

If you look at http://obihai.com/OBiDeviceAdminGuide and search for the phrase 'A screenshot of the WiFi Settings device page is shown below' you will see that DHCP is the default.

drgeoff, Thank You.

Indeed somehow that setting for the ObiWiFi got changed to Static.  It all makes sense now, except for how it got changed.  Obi works with the ObiWiFi now.  Your replies to my questions have been both patient and thorough.  Thanks again.

I apologize if this is not exactly along the same thread, but I haven't used the Forum much and could not find out how to create a brand new one.

I also have Google Voice, along with CallCentric for 911 service, using the OBI100.  In the future, we might be moving to an apartment complex with free WIFI they say works very well, but I may not have an ethernet connection to plug into.  So, my question is, can I configure an OBIWIFI with an OBI202 to work strictly with the complexe's WIFI?  I will have the password, of course, but I will not be able to configure anything with their router.  I plan to convert my Google Voice / CallCentric setup to use the new plan that Obi has with Phone Power.

Will the WIFI only connection work fine without any router or ethernet connection of my own?  Thanks,  --Jerry in Michigan

Thanks for the link - I had already seen that, but it does not specifically address my question of whether this set up, using an Obi equipment with a "hotspot" type wifi router, which I would have no way of configuring, would work with the new Phone Power plan and the Obi.   Does anyone know if it is likely to work ok?    Thanks,  --Jerry

It should work to some degree, but whether or not it will work to your satisfaction in that environment (shared WiFi) is going to be heavily dependent on how many other users are simultaneously using the same network, and the signal strength at the spot where you locate your OBi.  WiFi was never designed with VoIP in mind, especially when shared by several other users simultaneously, streaming netflix, porn, torrents, etc.  it's a "best alternative to nothing" solution.  You won't know until you get there and test it.  When you do move in, hook up a computer to the WiFi access point, and run the VoIP test here:
http://myspeed.visualware.com/index.php

This company's test uses a Java applet running on your computer to accurately simulate real-world SIP connections, and is the only meaningful test (vs standard speedtest sites which are useless for SIP VoIP).

You need to get a MOS (Mean Opinion Score) of at least 4.0 to enjoy reliable VoIP service.

I want to connect a obi200 with a USB wireless adapter to a hotspot.
The hotspot is a open network,
But requires the password when you open up a webpage after you are connected.

I have that password.

My question is,
Will I be able to do this with the obi device.

Thanks all!
