Help Samsung Galaxy S3 (i747) and SBG6580 modem

I posted a similar thread awhile ago and really didn't get a working response. The issue is that I have a Samsung Galaxy S3 (i747) and whenever I send or receive an MMS message on my phone when connected to WiFi, it not only knocks my phone off of the WiFi, but disables the WiFi on all of the other devices in the house. We can still see the WiFi signal, but can't connect to it. We have a Surfboard SBG6580 combination cable modem/wireless router. As soon as a picture is added to a text message, my phone buzzes, it displays a message that the file is too big and it is condensing it and then the WiFi gets knocked out. AT&T says they can't figure it out. The cable company has been here several times and have replaced our SBG6580 three times with new modems and have run new cable. This does not happen to anyone else in our house that has iPhones or an HTC Mini. Just mine. And it has to be the Galaxy that is the issue because our niece has one and as soon as she comes to our house, her phone knocks the WiFi out too. I am beyond frustrated and am asking for help. Please!
 
I can send and receive messages, but as soon as I try to send one with a picture attached or receive a picture, it knocks out the WiFi. Our devices can still "see" the wireless signal, but won't connect until you reboot the modem/router.

It's a combination modem/router all-in-one, so I don't know how I'd take the router out of the equation. And I'm on the WiFi at work, and it doesn't do this.

that router/modem has terrible reviews, especially the wifi...If you can, i'd get another access point to bridge off that modem or get another modem all together. I don't think there is anything you can fix or setting you can change in your phone that will help.

Ok. Assuming we'd go the route of getting a new cable modem and WiFi router, what would be the recommended choice?

Wife uses computer for social media, etc. Kids have Ps3 and I need a reliable connection to remote to work. We all have smartphones, Kindles, etc.

I know every situation is different, but curious as to what others (i.e., not me) would recommend.

I really appreciate the feedback. Thanks.

Netgear n900 routers are pretty good for a reasonable price. Cisco/linksys products can also be decent choice. I'd recommend going through a few reviews(consumer and professional) of routers you might be interested in.

If you do connect another router to your current surfboard modem, you will want to put it into "bridge" mode for best results. How to Bridge a Motorola SBG6580 | eHow

I'm just going to throw this out there because something equally puzzling happened to me the other day. I had just copied some recorded TV shows to my new-ish Galaxy Note 10.1 tablet when just like you, everything lost connectivity with the internet.

Apparently the tab was syncing the video files with my G+ account and had maxed out the bandwidth with a high priority so nothing else would get through. As soon as I took the tablet offline, everything came back.

Ok so i have installed the same modem in the house and all works fine but my samsung galaxy S3..... another person in the house has an S5 and theirs worked fine no problems ironically considering the network firmware/rom config is almost identical. Anyway.... It sounds dumb but this should fix your issue...go into the router settings, Add your phone MAC into the trusted pool / Leased IP address to MAC pool, but before doing that simply just switch the WPA/WPA2 Encryption from the default AES and make it TKIP+AES since the galaxy wont accept AES, you might have caused a slight ddos or over flow from attempts or simply a unknown request that errored out the modem causing a soft reset. good luck :)

EDIT: Also when forcing a way through with setting a static ip... it will connect and seem fine no matter what with any device.... this does not mean it will be allowed access,network gateway passage ;-P..... just incase you think theres some crazy force against you after trying that and seeing a connection established its just a false negative ;-) so if it is not going to work with DHCP it rarely will work with Static unless it is a matter of DNS concerns with host servers and bla bla but usually this DNS issue does not concern those with connecting at home unless they have a home server network aka personal data center setup ---
