URGENT ISSUE w/ Simultanious Broadband Connection

Hello, i am completely new to what the tech so i hope i have not made too many mistakes already. I urgently need help! I have a NETGEAR N600 WNDR3400 Wireless Router the serial number is 2bk2067u013c1. I have an OS on my laptop of Windows 7 and the home desktop PC has an XP OS and is the computer we used to install the router. My laptop is a Samsung Notebook. The router is supposed to have the ability to run both bands simultaneously however, any device can only pick up the 2.6 GHz and not the 5. I also have Comcast as my internet provider if that provides any help to anyone. Anytime the phone rings we lose network connection, i believe this is because the wireless phone runs on a 2.6 band as well and causes interference. Which is why i believe i need to run of the 5 GHz in order to have limited interference with my network. Immediate assistance would be lovely, thank you

Hello Marcelo and Your notebook may have a Network Interface Connection device that would allow it to connect to either 2.6ghz and/or 5.0ghz signal from the Router. The Desktop "may" have a Network Interface Connection device, that is only responsive to 2.6ghz. (I don't know that for sure, but suspect it) Since you set-up your Router using the Desktop, it may have configured the Router to only broadcast at 2.6ghz. You "may" be able to Reset your Router to factory defaults and then freshly configure it, this time using your laptop to configure. If you do that, your "laptop" may be able to function with immunity from your cordless telephones, while your Desktop may continue to fall victim of connection loss. That happened with my Desktop (an older machine) in my household where a passel of college friends of my Son frequently gather. It only took once, of hearing the chorus of voices: "Dad, don't use that phone, we all loose our internet when you do." Thereafter, I reconfigured AND connected my Desktop directly to the Router via Ethernet cable. You will end up with "two" wireless connection sources available plus a wired source. The higher frequency one will have the same basic "name" but will often be tagged with the additional term "media" (or something else depending upon your Router) which will indicate the difference. No problem-o. Best Regards

Hello unfortunately this still did not work, i am unsure of what is wrong i have tried all i could think of. I believe we are just going to buy a new router. If you have any suggestions they would be greatly appreciated. Once again i really appreciate the advice technology never works as it is supposed to at my house for some reason that is quite odd. Thank you again

Chances are you don't have any devices that will even use 5Ghz. Even most of the brand new laptops right off the shelf don't have 5Ghz wireless-N support. You didn't specify details about any of your computers, so who could know… Just because something says it is Wireless-N capable doesn't mean it has 5Ghz support - and probably doesn't.
