Remember thinking that a 56K modem was fast? The Internet has grown up since then, and so has our home networking needs. Instead of plaything LAN Frisbee with MP3 files, today we toss around gigabytes of data and stream high definition movies from room to room. The good news is you don't have to rob you children of their college funds to keep up with the times. Upgrading to 802.11ac on the cheap is as easy as taking advantage of today's top deal for a D-Link DIR-850L Wireless AC1200 Dual Band Gigabit Cloud Router for $70 with free shipping (normally $130; use coupon code: [EMCWVXP57]). This router serves speeds of up to 300Mbps on the 2.4GHz band and up to 867Mbps on the 5GHz band, has a cloud management feature, and is backwards compatible so you can still surf the net while shopping a wireless AC adapter.
