3g Microcell and Charter Cable

Hi

 

I have had a 3g microcell for over a year.  Suddenly this week the 3g light starts flashing and phones no longer connect.  I have:

 

deavtivate and reactivated too many times to count

factory reset my modem, router, microcell

replaced microcell with new one

opened all ports listed in various posts and att support site

turned cellular data and 3g data off on iphone

used priority set up (modem then 3gMC then router, this is how I am configured now)

 

What ever I try, there is still no connection back to att network.  ATT support says it must be charter cable and charter cable says it is att.  The only port I can not touch is 123 NTP.  I don't know what is hooked up to it, but it is not accessible to me.  However, using the priority config should bypass any port issues...right?

 

Please help.

That might work as well. I haven't seen the V-adapter so I'm not sure what configuration options there are. I was able to get a hold of one of the MicroCell engineers and that was his suggestion.

 

SIP uses UDP and may be locked into specific ports. It also has difficulties with NAT.

Re: 3g Microcell and Charter Cable

The V-adapter is a one port basic router and does have a webpage accessed by IP address to make simple settings changes.  I know it isn't as robust as a decent router/gateway and I don't think you can port forward with it but I'm not sure.  It sells for $20-$30 so it can't be that good.

 

I've done speed tests with the Microcell in front of the router and it seriously degrades bandwidth to everything downstream of it.

 

I've read several posts about connecting a V-adapter to a router and it is commonplace.

Re: 3g Microcell and Charter Cable

I suppose the OP could contact Vonage and ask what he can, or cannot do, with the V-adapter as far as configurability.

Re: 3g Microcell and Charter Cable

Thanks guys for your latest posts...

 

Regarding my Vonage issue... I agree that it should be behind my router but in the past when I've tried to set it up that way, the configuration was a real beast to get it to work.  At the time, Vonage had suggested to place it in front of the router but that's also causing double-natting which no one needs.  

 

What I'll do is do a full reset on my Vonage box then hook it up behind my router to minimize overall speed latency and the double-natting issue.  I'll also disable DHCP in there.  You guys are right and that V-Adapter is pretty cheap and its firmware is very limited as far as custom configs go.  I'll put it in the DMZ too as suggested.

 

Hopefully these changes will take care of the Vonage issue.  I'll keep working on the MCell one too as that's driving me nuts now since it's not working properly.

Re: 3g Microcell and Charter Cable

Just remember that a double NAT is a big no-no with the MicroCell. I'm sure you already knew that but it bears repeating. It's covered in my Guide.

Re: 3g Microcell and Charter Cable

Yes, I understand that it's certainly not a good idea to double NAT.  It just amazes me how my configuration had always worked well in the past, up until about 2 months ago when suddenly call quality on the MCell deminished drastically and some Vonage calls too..  That was at about the time Charter was starting to make back-end changes to their network so that's why I posted my original message on here, pointing my finger at Charter.

Re: 3g Microcell and Charter Cable

I think I mentioned this already but I have been unable to contact the Charter Engineer (SVP-Corporate) who was so helpful when this happened in another region about the same time. His Charter email address now bounces back as undeliverable. I've tried to email him from two different email accounts (including my personal email account) and get the same results. We're trying from this end but are running out of ideas. Your best bet, unfortunately, is to start pressuring Charter to do whatever they did to fix their network boxes after the upgrade for AT&T VoIP in the Dallas-Ft. Worth area, that they do the same for your area. It may end up that either Vonage or the MicroCell will work but not both.

Re: 3g Microcell and Charter Cable

Guys, just wanted to give you another update...

 

I did a full reset of my Vonage box, placed it behind my router and assigned it a static IP.  It has been working well so far and my general Internet speeds have greatly improved since that device is no longer upstream of the LAN.  So, thanks for that good suggestoin.

 

Now, the MicroCell seems a bit better now that the Vonage box is out of they way, just as long as I have no other devices on the network using any bandwidth.  As soon as I use other devices (not all at the same time of course) the MCell outbound quality deminishes suddenly.  (other devices accessing Internet include your typical things like two laptops, two cell phones, my DirecTV DVR, XBox and an iPad).  That's basically it.

 

I have the 30/4 Charter HSI package but maybe the 4 Mb up just not enough speed to handle my devices, including the Vonage and MCell boxes that are constantly listening on the LAN, let alone passing voice traffic when active calls are made.

 

I'll contact Charter for them to test my line, to verify that's all good then will possibly consider bumping up my HSI package to their next teir if available.  

 

Otto:  I'll pressure them to fix their boxes for the AT&T VoIP issue as well.

 

Thanks.

Re: 3g Microcell and Charter Cable

It sounds like Vonage is your problem, that and the fact that it could be a priority issue as well where the MicroCell loses out to Vonage or your other devices. I have quite a few devices on my LAN as well but none of them interfere with the MicroCell. I can be streaming Netflix, have both laptops on the internet and still make and receive cell phone calls with no issues at all. I don't think bumping upload speeds will fix anything. My upload speeds are 1.0Mbps and I have aboslutely no issues. It may come down to choosing between Vonage and AT&T, or dealing with the connection issues when they come up knowing now what the problem probably is.

 

Have you tried to assign a static ip address to the MicroCell (based on its MAC address) and then forward the necessary ports to it? That may give it a bit more priority.

Your router has QoS and as I suggested previously, you should set the priority of your Mcell to the highest setting based on its MAC address by doing the following:

 

Open your router admin page, select "QoS setup".

On that page, check the box for "Turn Internet Access for QoS On"

Click "Apply".

Then at the bottom of that same page where it says "QoS Priority Rule List", click on "Setup QoS Rule".

On the "QoS Priority Rule List" page at the bottom of the list of rules, click on "Add Priority Rule"

Once you are on that page:

 

1. Select "MAC Address" from the "Priority Category" list.
2. Enter the MAC address of your Microcell in the field provided. 
3. You can also enter a name in the "Device Name" field.
4. Select the priority level: Highest.
5. You can also type the name in the "QoS Policy for" field for this rule.
6. Click the "Add" button.
7. Click "Apply".

 

This will hopefully minimize the impact on your Mcell when your bandwidth is tight.

As far as going to a higher tier of Charter Internet service, you mentioned that you are currently at 30 mbps down and 3 mbps up.  Are you sure it isn't 30 down / 4 up?  That's what my Charter service tier is.  You may be able to go up to a higher tier like 100 mbps down for an exorbitant amount of money but I don't think your up speed will change.  I may be wrong.

 

Try my suggestion first and see if your situation improves.

Re: 3g Microcell and Charter Cable

Thanks again to you both...

 

Yes, I have the MCell set on a static IP and have QoS set to high priority for its MAC.  The default QoS rules in the Netgear router also have general "IP_Phone" services set to high as well.  It also has a default "Vonage_Phone" rule set to high in there too.

 

Yes, in my previous post I mentioned that I'm on the 30/4 plan also.  I'll try the port-forwarding trick for the MCell to see if that helps.

 

Otto: Yeah, I agree that my 4 Mb up shouldn't be an issue for all these devices.

Honestly, I may just dump the Vonage service soon all together since services like the new BBM v2.0 with BBM Voice are available.  The only reason I have Vonage is to make calls to Canada since I have some family and friends there.  With more vendors offering free VoIP call services like BBM, I can only imagine Vonage will go out of business anyways.

Re: 3g Microcell and Charter Cable

Sounds like you've already set the QoS priority to high for both so maybe port forwarding will give the MicroCell an edge as far as priority goes.

 

Vonage seems to be a survivor. They were almost down and out a couple of years ago because they had all kinds of issues (my bro-in-law had them) but seemd to have bounced back. In fact, I think my bro-in-law may have gone back to Vonage. I should go ask him about the nuts and bolts of his service if he did. He's in the networking field so he may have some insight. Don't know why didn't think of that before Smiley Sad

Re: 3g Microcell and Charter Cable

OK, I've got port forwarding to the MCell IP for ports 443, 500 and 4500 (public and private) but am not able to get UDP 123 to stick in the router config.  It keeps telling me that the port is already being used.  I've even temporarily disabled UPnP but no luck.  I'll try some test calls later tonight to see if it's better with those 3 ports forwarding.

 

No worries about asking your brother-in-law earlier but if you happen to get some feedback from him on his Vonage setup, that would be great!
