D-Link DIR-845L Extreme Range Dual Band Gigabit Router

Got a new router from Costco, $100 plus tax. It is named as Extreme Range Dual Band Gigabit Router. Extreme Range, means it can cover a large house. Dual Band means 2.4G and 5G work at same time. Gigabit means it has Gigabit Lan ports and Wan port.

It is not my first D-Link router. My first one is WBR-1310 Wireless router. I bought it 5 years ago. I feel comfortable with D-Link products.

How to choose the right router

To choose the router or upgrade your home network, first you should know what standard you need.
There are three main standards on market now.
Standard Max Speed
802.11g 54Mbps
802.11n 600Mbps
802.11ac 1.3Gbps
802.11g was introduced many years ago, I wrote a post eight years ago related the wireless network.
802.11ac is still a draft standard. It means most products from different company are not same. They may not work together compatibly. The good news is that IEEE will issue the final approved version of 802.11ac the end of this year 2013. Here is the timeline.
The Max Speed described above is in theory. When the router working inside the house, walls, furniture, these kind of obstacles reduce the speed by 50%.
There are also frequence, bandwidth, channel issue for your router.
for 802.11g, 2.4GHz, there are 13 channel. 20MHz each channel
for 802.11n, 2.4GHz or 5GHz, 20MHz each channel, bonding channels.
for 802.11ac, 5GHz,
Bonding channels is double the bandwidth, or 40Mhz. It means faster.

In the server terminal window, I can ping domain and get the IP address of Google.com, but I can not traceroute path to Google.com. It said network is unreachable, something like that.
When I tracert my host from Windows, the error looks like below:
