If you have a computer that has slow wireless networking connectivity, you can always change the card out, but for some people that isn’t the answer. A USB network adapter that supports the faster tech might be easier.

Trendnet is here to help and they have a new USB network adapter that is dual band and will work at 2.4GHz or 5GHz. That means that HD video and other bandwidth heavy things can use the 5GHz band. The adapter has WPS for easy setup and a MIMO antenna for the 450Mbps transfer speeds. It will cost you $90.

Who says that all WiFi routers need to look out of place in your home? Not I and certainly not Netgear. The N750 keeps its antennae stashed inside and out of sight. Your wife will certainly appreciate that as it at least keeps a low profile.

Aside from looking pretty sleek, this dual-band 802.11a/b/g/n router is capable of speeds of up to 450Mbps over the 5GHz band and 300Mbps at 2.4Ghz, for an “aggregate combined data rate” of 750Mbps. That just means that you can connect one device in either band without the transfer rate of the other suffering. You won’t get full 750Mbps. The N750 also sports a ReadySHARE USB port for network storage, parental controls, and guest access. All for just $150.

Netgear has announced that it is now shipping the N300 Wireless ADSL2+ modem router. The device is basically a DSL modem with an integrated 802.11n wireless WiFi router. The feature that you will appreciate the most is that it has failover if DSL goes down.

The failover function is thanks to a 3G USB modem that you can plug into an attached USB port. When DSL is out the 3G modem kicks on automatically and once the router detects that your DSL is back the 3G modem stops.

Netgear has unveiled the second generation of it’s very useful Push2TV HD TV adapter. The device uses WiDi (Wireless Display) to push a computer’s screen content to an HDTV connected to the Push2TV box via an HDMI cable. Hence the name. This second generation of Push2TV supports 1080p at 30 fps (previously 720p) with a shorter lag time than before.

Also, Psuh2TV now works with discrete graphics processors, which you absolutely need for gaming. The NetGear Push2TV will cost about $119.99 and will be available sometime before march of 2011.

Netgear has surprised no one by announcing a few more HD media players. The NeoTV 550 and 350 are both similar to the Digital Entertainer Elite which was released last year without a 500GB internal hard drive as well as access to VOD services including CinemaNow.

Both are capable of playing a long list of codecs in full HD from a variety of attached sources like USB, eSATA (in the case of the 550) or SD storage, as well as streaming content from UPnP, DLNA or WMP11 networks. The 550 has support for external Blu-ray drives and BD-Live.

Netgear has a new wireless home theater kit that comes with some awesome features. The kit consists of a pair of adapters that you plug into your router or gateway while the other connects to the computer, gaming console or Ethernet/Wi-fi. You can purchase more adapters to expand the functionality of your system as well.

This is a good solution for those who are tired of the limitations of Boxee for instance. If it performs well, it’s a great way to keep esxpanding.

Netgear’s MBRN3300 comes from a collaboration with Ericsson. The unusual device can use an internal 3G modem which includes HSPA+ at about 20Mbps, while sharing that link via 802.11n Wi-Fi or through one of the four 100Mbps Ethernet ports.

Owners can also switch off the 3G, Wi-Fi or both when not in use. The MBRN3300 is for households where regular cable, DSL or fiber isn’t available, and for those who rely on just mobile local networks. You can even charge it up in the car with the optional car charger and a battery pack. Nothing on pricing yet, but Netgear primarily intends the router as an option for carriers.

It used to be that the wireless router only did one thing and threw in a few wired ports for computers close to the hub. Today the wireless router is becoming a converged device that serves multiple purposes. Netgear has announced a new router called the Rangemax Wireless-N Gigabit Router with USB model number WNR3500L.

The router has gigabit ports on it for fast wired connections and has a single USB port on it. The USB port will allow you to share USB peripherals with the wired and wireless network including hard drives and other devices.

Netgear’s Digital Entertainer EVA2000 is perfect for those who don’t have a home theater PC or a networked console. The device will stream all of your PC media onto your TV. It connects to the TV via HDMI/composite and to your router via ethernet and it will stream a bunch of codecs from your PC or networked storage, as well as load media from a USB drive or stream YouTube from the web.

There is a catch of course. You need to purchase PlayOn for $40 if you want to stream video services like Hulu, Netflix and CBS from a computer. That takes the price from $150 for the Netgear Digital Entertainer up to $190.

I have wished on several occasions that I could get my DVR connected to the internet. The problem for me is that my house is larger and my router and modem are a long way from my living room and running new cable through the walls is not an option.

At CES Netgear was showing off its Home Theater Internet Connection Kit and the company has announced that the kit is finally shipping. The kit is nothing more than a powerline networking system that includes a switch for the entertainment center with four ports and the adapter that plugs into your internet router.

I would really like to connect all of my home theater components to my wireless network, but most of the gear I have can’t connect wirelessly. My router is in a different room and running wire through my walls is much more than I am willing to do. Netgear has launched a new Coax-Ethernet adapter kit that might be just what I need though.

The kit is called the MCAB1001 Netgear MoCA Coax-Ethernet Adapter Kit and is designed to offer the bandwidth needed to distribute HD video and multimedia content to your Blu-ray player, TV, and cable box.
