HELP - 3G light is flashing, microcell was previously working fine

Hello,

 

   I figured it was worth posting here so I have yet to have success with anything else. 

 

Background

 

I live in an area almost exactly inbetween three AT&T cell phone towers, so subsequently my phone is constantly switching singnals from one tower to the other giving me very inconsistent service.  After diagnosing the problem with AT&T about six months ago they sent me a micro cell free of charge, and it worked absolutely fantastic until....

 

The Problem

 

About a week ago my microcell's 3g light started flashing, this had happened once or twice before so I performed a simple reset but it did not fix the problem like before.

 

  •   I tried resetting my modem, router, and microcell
  •   hard resetting my microcell for 30 seconds
  •   de-activing and re-activating my microcell twice
  •   checking my power cord to make sure it was the right voltage
  •   getting a replacement microcell sent to my house
  •   setting up my microcell in the alternate arrangement (modem-->microcell-->router)
  •   updating the firmware on my router

and none of these fixed the problems.

 

My current internet is about 30mbps DL and 10mbps upload so that isn't the problem

The ports on my router are all opened, and nothing has changed to effect that

 

After going extensively through the forums I am kind of at a loss of what to try next.  Any suggestions from people on the forums?

 

I am currently located in the East Bay of California (Alameda, CA)

 

Thanks very much.

The MC dropped one call yesterday.  Still a lot better than the 151 was doing.

 

This may be a stupid question to some but in trying to really look at the router settings and see what can be done I am reading other places and seeing things that might be good and some not so good so here we go-

 

Will it help the microcell to disable stateful packet inspection? And in turn will that make my router less secure with NAT still working?

 

Will putting the microcell in DMZ help or hurt or even matter and if I do put it there then you don't need the port forwards correct?

 

My router has a setting for sip alg and I see that's something for voip, should it be enabled or disabled?

 

And just for fun should the CTF be disabled or enabled?  I see by reading other pages that having it enabled slowed down computers in the network but was wondering what your take on it is or if it even matters for MC operations.

I would also like to point out that at this point I am pretty happy with the mc staying connected now that I have opened this can of worms I want to do everything possible to lessen my latency when using the microcell.  My wife isn't bothered by the latency at all but when i talk on the phone I tend to talk over people and they do the same to me.  If I can rewire the whole house using a pot splitter and replace all the jacks and that helps then so be it.  I am also probably going to upgrade my bandwidth because I can and streaming netflix is better with the increased bandwidth too.

I have also ran about 5 voip tests this morning and it's def better than it was, not passing everytime but passed twice out of the 5.  I enabled sip alg too so I'm not sure which thing helped, either the sip alg or fast buffer.  Guess I could go back and disable sip alg maybe.

SIP ALG ( Session Initiating Protocol Application Layer Gateway) is used by the Vonage VoIP service to try and avoid configuring static NAT on a router. It can be enabled by default on a lot of routers. ALG can help in solving NAT issues but in fact a lot of router's implementations of the protocol are wrong and will break SIP. The MicroCell does not use SIP ALG and because it can be poorly implemented, it can cause all kinds of issues. If your connection works with SIP ALG enabled fine, but if it works better with it disabled, then that's an indication that it is being poorly implemented by the router and you should disable it.

 

It looks like your connection has all kinds of noise on the line somewhere which is interfering with VoIP regardless of the router settings.

I am sure hoping that the noise is in my lines and it will get fixed when I do the rewire.  Waiting of the phone guy to come and replace the TNI so I can install the pots then run the wires.

If the noise is in your existing home wiring, then rewiring is a drastic but perhaps necessary step to eliminate that as a possible cause.  I hate to be pessimistic but I suspect your problem may be past your home wiring and exists somewhere on your ISP's side of things.  I've had problems with packet loss in the past and had the ISP send a tech out.  They eventually found some connectors on the pole outside my house that had water in them and a bad repeater/amplifier further on down my node.

 

If I were you, I'd have a tech come out and test your wiring to see if there is a noise problem and then trace where the source is.  That can save you time and money if the problem isn't in your home wiring.
