Hi,this is my first post,excuse me if do any mistake or if i do some typoerrors
So,as the title says,my 3G Modem Adapter (Olicard 200 14.4mbps from Olivettti) keeps switching from UMTS and HSPA+ and because of this my ping drops to 900ms (usually i have 60/70ms) evert 3-5 min (the time the modem keeps switching) for about 3-6 seconds (the time it takes to switch from HSPA+ to UMTS and viceversa.and during the switch i have 0 byte sending...basically im not connected to the internet for those 3-6 seconds).
What i did:
Updated the Olicard 200 software and firmware
Updated my wirless and other network drivers
Factory Restart
Tried changing channel,port or moving around my house (even if i have a 4 out of 5 signal)
I tried TCPOptimizer and Advance System Care (Yeah,i know most of these programs just mess up with your registry files but at this point nothing could go worse)
Updated video card (NVIDIA GT540M,yes,it's a old one i know) drivers (i googled about this problem and i found an article where video settings/or the card could cause these lags)
In my area nothing changed,only my OS changed on my computer (from W7 to W8 and then W8.1 Update 1) but it's because of the OS Upgrade,since it worked on W7 and W8. (When i installed W8 i had to wait until April 2013 for the software update...everything was running smooth.
Then i installed Advance System Care and i did Internet Optimization...nothing weird for the 1st week,after 2 more weeks my internet started random lagspiking like now.
After that i did a factory reset,wich didn't solved the issue.
I also changed some settings on the Power Managment (selective standby option)
But,i didn't called my ISP,since the first time i had a bad experience and here in italy the maximum help you could get from calling them it's "Have you tried turning it off and on again?" or "It's your PC for sure".
Any help it's really appreciated since i tried almost everything i could do (also modyfing my registry)
Sorry for this poem,but it's really frustrating for example while playing LoL and begin executed because those lagspikes)
Thanks for your time
 
There are 2 main things that can cause this. First if the signal quality is getting poor it may switch to another tower or the other band. It would be nice if you could put a antenna on this unit but it does not appear possible. Best you can hope for is a long USB cable and put it in a window.

The other thing that causes this is the cell provider trying to rebalance their network. This happens to me all the time. I am on a strong tower and for some magic reason I am moved to a lower signal level tower. From what i have been told by a number of people that work in the cell industry the providers will shift people off a tower just so everyone can get signal. Not sure what you can do if that is your problem. This is the ISP trying to be "fair" to everyone.....so everyone gets poor service.

Some devices you force to only use HSPA+ but you may just completely drop your session rather than it slow down.

If you can get on a LTE based system it is much more stable and many times faster. Still every once in a while my phone refuses to show LTE availability even though minutes before it was showing very strong LTE.

I knew my ISP could be the problem and probably it is,but im not really sure about this since it could be the modem itself doing this,but also the bandwith bugging out,i mean,the modem switch to better connection everytime i use internet for downloading or watching and when im not using a lot of bandwith,for example while playing games with only a few kbps,this will make the modem recognize the low usage and automatically switch,and this is happening in loop mode.

Yea i know but the ISP could just slow me down,and limit my bandwith but i don't think it's ISP related this issue.
Let me explain...With this 3G modem i have 10GB every month,if i finish those 10GB then they will slow me down to 64kbps (horrible thing) wich make my internet useless since i can't do anything "expensive" but they can't affect directly my network causing these switches...The best possible solution it's blocking the modem from switching from UMTS or HSPA and have a constant UMTS or HSPA. But unfortunately i don't know how to fix this. My signal it's strong enough and i don't have any speed issue,just this random "death" internet for those 3-5 seconds everytime
Anyway thanks for your help and time
