Modding the Arris BGW210-700
The Arris BGW210-700 is practically trash when it comes to its wifi because of the position of the internal antennas according to the logic board layout. Modding can increase the wifi coverage and I would like to make this happen. I searched online and found the logic board schematics and I see it only has 3 U.FL connectors to soldered directly to 3 copper ending which are the ones acting like antennas. These are facing the front of the stupid thing instead of all around to have a proper coverage.
If I opened the box and punched the case holes in the reference locations already marked by the manufacturer; would this void some sort of warranty? Would I get into trouble with Att by modding the factory moddable case? I want to increase the range of the wifi signal by adding high output external bi-directional or omnidirectional antennas without adding additional hardware since Att is being stupid about not letting us use our own router.
