MiFi2200 Constant disconnects when using wifi

I am currently using a mifi with two Macbook Pros, an Ipad and 2 iphones and it constantly is resetting the cell network connection when connecting using wifi. Whenver I keep the administration screen open it keeps going dormant, disconnecting, connecting as much as 2 to 3 times a minute. I have tried just about every modem / wifi configuration including turing off encryption and turning off the standby option. However if I tether the modem and connect with VZManager it works great for hours at a time and is about 3 times as fast. After reviewing the forums I am guessing this is not a Mac related issue however I could be wrong. Are other mac or PC users having this same issue no matter what machine you are using?

My last call to verizon support they said it was an "IP Conflict". However they would not give me the information necessary to diagnose what IP they were talking about. I have a feeling it is their IP and not the internal network 192. IP that the mifi is giving out.

Here is what I have donet to try and fix it:

- Testied it in 3 different states.

- Tried all different wifi configurations

- Factory reset the device

- Tried only one mac at a time

- Exchanged the mifi for another one.

I am about to exchange it for the regular usb stick modem and get a cradlepoint router.

Peace

Marc

12 page thread with people having similar issues, myself included. We've probably had about 45-50 disconnects in <24hrs. Finally got a support tech with a little bit of sense and we're going to try a hybrid prl. If nothing has improved by Monday, they're going to overnight another Mifi 2200 and send out a tech to check the towers if that doesn't work.

What type of computer are you using? Also did the tech mention anything about ip conflicts to you? Given the only IP that changes is verizons I am thinking tech support does not have all the info to diagnose this. Also last question but does this only happen when you are using wifi or when tethered also?

Currently running two laptops with Windows 7 but it also did the same thing with an XP machine. Haven't had any of the techs mention ip conflicts. The continuous disconnects only seem to happen when using wifi. Doesn't seem to matter if there's 1 or 3 computers connected via wifi, but the signal usually drops after 15-30min. Looks like the prl change went through as it's showing a different id under modem status on the web interface and has been connected for 2 hrs without a disconnect so far so we'll see if that works.

ha, as soon as I posted that it disconnected. Signal strength seems to have improved and is showing 4-5 bars and dBm readings in the low to mid 80's instead of the 2-4 bars and mid to high 90's before.

I hope they get this figured out for you. I am now on a regular usb modem and ditched the mifi. When I get home I am ordering a cradlepoint router so that I know I have a solution that works. At the verizon store the guy was very surprised to see the connection totally reset when hooked to my computer. This was with their in store mifi also with an older firmware. Is PRL the just another name for the firmware?

Having the same exact issues using the PC5750 card.

Well the replacement started doing the exact same thing. Spoke with a tech support rep last night who had me manually assign the ip addresses rather than using DHCP from the mifi. Oddly enough, it's been connected for over 14hrs with no disconnects. Maybe it is an issue with the mifi assigning addresses automatically

BruceLang

Interesting - would you provide a summary of how to manually assign IP addresses? Are you talking about using assigning static IP addresses to all devices using the MiFi2200? If yes, then I "may" be able to figure it out. Here's to your continued success.

PJNC284

yeah, rather than using DHCP to auto assign the ip's, just assign each device a static ip. For a Windows PC, just open network connections in the control panel. Right click on your wireless adapter and choose properties. On the Networking tab that pops up, select TCP/IPv4 and click properties. Then select Use the Following IP Address and Use the following DNS Server Addresses and enter the desired settings. The default gateway and primary dns should be the ip address for the mifi which is 192.168.1.1 from the factory. For each device just enter a different static ip address such as 192.168.1.x (where x is anything between 2 and 254) with 255.255.255.0 as the subnet. Not really an end all solution imo if you take your computer elsewhere as you'll need to go back in and set it to obtain automatically but it does seem to provide a more consistent connection. Only issue now is flash intensive sites such as farmville on facebook slows the internet to a crawl but that's probably another problem.

I have been having the same problem since I got the Mifi thru Verizon several months ago and the strange thing is that before that I had the Sprint MiFi and had it for about 8 months and I never had any problems with disconnect with that device. I just tried the sugestion to set the Ip address which I have tried but within 5 minutes the device disconnect me and also disconnected from Verizon then reconnected. I have an old unlimited plan and use it, and I have to wonder if Verizon is resetting this to keep the traffice down. Anyone else see this happening with their unlimited plan?

TJ_FTLGR

I just tried direct connecting it to the computer and running VZAccess manager and it has staid connected for 30 minutes but I have low signal as now I cannot place the device in the window of the house.

I know this is a redundant solution, but has anyone tried using a cradlepoint router with the MIFI?

marcomatic

I switched out a mifi for the usb modem with a cradlepoint and it worked great. Speed was much higher than when using the mifi as a wifi router. Like many others if I used the mifi directly connected over usb it worked perfect.

Another Tip is you could have kept the MIFI and tether it to the CradlePoint Router, It would have worked perfectly.

Plus it keeps the mifi charged at the same time and when your ready to go in a hurry the Mifi is all charged up so you can take it with you..

I got this tip from http://www.evdoforums.com

The MiFi disconnect issue has been FIXED by Verizon. To see the fix (and the story about how I emailed the CEO of Verizon to get the fix) see http://go.DanielOdio.com/MiFi

It would be so nice if upgrading to v159 fixed the issue, but for me at least it did not. I upgraded months ago and the problem persists.

Concur, in my case v159 actually caused the problem unless there was some miraculous alignment of the planets that day because I never had the issue before I made the mistake of upgrading the FW and it has been near constant since the fatefull day.
