If you have the money, yes. I replaced my old router (The one I suggested to you.) with that Cisco E4200 for security reasons and I love it.
(Note: For me, the Netgear was faster and had better signal, but the Netgears administration sucked and the firewall was too basic. On my Cisco E4200, the scheduler doesn't work, if you have it shut off the internet at a specific time, it wont come back on, you have to reset the router manually.)
Yes, I was using this device at work to run:
A 16 channel ARM HD-DVR surveillance system streaming all 16 channels to 1 client and 1 channel at a time to another client.,
A Windows Server 2008 R2 PC running QB POS 9.0 serving 5 clients
5 Win7 workstations
3 Win7 wireless laptops
6 wireless smartphones
2 wireless printers
4 shared wired printers
and a partridge in a pear tree.
(This device was personally handling the ARM DVR, the POS system, & all wireless devices.)
I was so sadly disappointed when it started to kick in that the Netgear was better.
I myself would always pick Cisco over anyone.
Numbers don't lie, and the Netgear performed faster in the same environment.
