D-Link’s new flagship Wi-Fi router (DIR-895L) is a prime example of the arms race among networking vendors since the latest 802.11ac Wi-Fi standard was introduced.

Manufacturers have been steadily launching new routers, with each iteration touting higher transfer speeds. But these speeds are aggregated across multiple wireless bands and do not reflect the actual bandwidth available for a single client device.

For instance, the D-Link DIR-895L is marketed as an AC5300 router (5,300Mbps), derived by adding the transfer speeds from its three wireless bands. For a single client such as a smartphone or tablet, the DIR-895L will not be any faster than a basic AC1300 router.

But the D-Link’s dual 5GHz and single 2.4GHz bands are useful for homes that are increasingly cluttered with Wi-Fi devices. Older clients that support slower Wi-Fi speeds can be put into their own wireless bands without affecting other faster devices. The router does this automatically via a feature dubbed Smart Connect.

Because of the competition among manufacturers, advanced features often make their way into routers before they are widely adopted. These features usually stay dormant till the manufacturer deems it appropriate to enable them via a firmware update.

Take the Multi-User Multiple Input Multiple Output (MU-MIMO) feature, which is not yet supported by most Wi-Fi clients. This feature lets the router send data wirelessly to multiple clients at the same time. It is currently disabled on the D-Link DIR-895L.

Angular in profile, and with eight detachable and adjustable antennas, the red DIR-895L cuts an eye-catching figure. It can be mounted on a wall, though I am not comfortable doing so because the router is relatively heavy.

The DIR-895L has four Gigabit LAN ports at the back, along with a USB 3.0 port and a USB 2.0 port.

Features that you’d expect from a modern router, such as parental controls, guest networks and the ability to share files over the Internet, are all supported.

The router’s web-based interface looks slick and is easy to navigate. By default, advanced features are hidden from users to reduce screen clutter.

However, the router can take varying amounts of time (from 25 seconds to 80 seconds) to save changes made to the settings. The good thing is that the interface always indicates the exact amount of time it expects to take. Still, I was expecting the router’s dual-core processor to run faster.

Performance could be better. The router recorded an average download speed of 501Mbps, which is significantly lower than the top speed of 695Mbps managed by one of its rivals, the Asus RT-AC5300 ($469).

If the ADSL light does not turn on, this means that the modemcannot establish a connection with your ISP. There are severalsteps you can take to try and resolve this problem:

d-link-dsl-2730u

  • Verify the ADSL cable is securely inserted into both themodem/router’s ADSL port and the microfilter.
  • If you have multiple telephone sockets on your premises, ensurethat the modem/router is connected to the master socket, i.e. theone closest to the point the telephone line enters thepremises.
  • If you have other devices attached to your telephone line,ensure that these are plugged into a microfilter. If the line issplit, e.g. using splitters or by having multiple extensions, makesure that the microfilter is plugged in before the split, or ensurethat all devices after the split are plugged into a microfilterthemselves.
  • Try upgrading the firmware on your router to the latestversion.

To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be another computer, or a URL.

Step 1 Click on Start and then click Run.

Step 2 Windows NT, 2000, and XP users type in cmd and press Enter (or click OK).

Step 3 Once the window opens, you’ll need to do a special ping. Use the following syntax:

ping [url] [-f] [-l] [MTU value]

Example: ping yahoo.com -f -l 1472

dlink-mtu

You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (1452+28=1480).

Once you find your MTU, you can now configure your router with the proper MTU size.
