In my last blog on 5 GHz spectrum, I discussed the recent FCC ruling that permitted outdoor access points to use the U-NII 1 band (5150-5250 MHz).
But the story doesn’t stop there. As mentioned last time, there are significant technical challenges to using the 5 GHz band. It is not cleared spectrum. It contains incumbent uses that are important for national security and public safety. Therefore, it is imperative that Wi-Fi not create harmful interference to these incumbent systems. Cisco will not settle for less.
On the topic of interference, a particularly interesting component of the same FCC ruling that opened the U-NII1 band for outdoor AP’s is that it also re-opened the Terminal Doppler Weather Radar (TDWR) band (channels 120, 124, 128) with new test requirements for DFS protection. Hold on, let’s backtrack a bit before diving into what this means:
What is TDWR?
In brief, Terminal Doppler Weather Radar (TDWR) “is a Doppler weather radar system used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the United States.” TDWR uses the frequency band from 5600-5650 MHz which is why wireless network equipment needs to be proven to “do no harm” to TDWR. If you’re curious for more information on TDWR, then please click here and/or here.
A Brief History
Many of you reading this will recall that the FCC closed the use of the TDWR band several years ago as the result of numerous reports of wireless equipment creating interference with TDWR. Read More »

You may not realize this, but Cisco has a thriving business building and selling networking products specifically designed for Small Businesses. Unfortunately, we know dealing with Cisco can sometimes be challenging for some smaller customers, a good example of this is managing software. Sometimes, it can be quite challenging to finding out whether equipment is running the latest software, and if not, how to get the latest software.
We recently announced a new feature called Automatic Service Delivery (ASD) on the RV215W, a wireless-n VPN Router that is in the Cisco Small Business Routing Portfolio.
The Automated Software Delivery service allows network devices such as the Cisco RV215W router or management tools such as Cisco FindIT to automatically retrieve software release information and software images from the cisco.com software library. This means that the user can be notified when a new software image is available, and they can obtain that software at the click of a button, rather than having to find their way through the thousands of files in the software library. If the user so chooses, a device can even automatically update itself, thereby ensuring the network is always running the most current versions of software.
This work was completed by our Smart Web Technology Group (SWTG). The API they developed enables client applications to retrieve vital software release and image information including release note, field notices and PSIRT information.
In order to gain access to this new feature, simply download the latest RV215W firmware form the RV215W product page and enable automatic updates on the Administration > Firmware/Language Upgrade page.
Look for more RV Series Models to get this free ASD Service.
So to wrap this up, we know Cisco’s Small Business customers face so many challenges and demands on their time, the Automated Software Delivery service is a great tool that helps make their job just that little bit easier.
Thanks for taking the time out of your busy day to hang out with us.

HP introduced the world to their OneView management appliance by comparing it to Cisco UCS Manager through a series of YouTube video attacks this past fall. I can almost hear the meetings… ‘Forget stealth, forget the high road – let’s attack the leader in converged systems management directly – let’s attack Cisco UCS Manager!‘ While we can’t help but respect HP’s gumption in attempting to pick on their #1 competitor, our flattery turned to dismay that HP continues to miss the boat on how UCS management truly works. Rather than respond with feigned outrage, we patiently waited for HP to release OneView for our own test drive. Read More »

New firmware (Ver.1.0.02) for the Linksys E4200 now provides support for IPv6. IPv6 is the next generation Internet protocol.
Cisco as an organization is committed to supporting the transition to IPv6 in all its products and services it provides to service providers, enterprise and consumer customers. IPv6 is foundational to the next generation Internet enabling a range of new services and improved user experiences.
As ISPs begin rolling out IPv6 service to their customers, consumers will need new routers and gateways that support IPv6 to participate in this next generation Internet. Today, Cisco will begin enabling IPv6 across its consumer line of routers including the Linksys E4200 Maximum Performance Dual-Band Wireless-N Router. It is critical that consumers begin looking for products and devices that support IPv6 or can be updated to IPv6. Cisco has been and will continue to be a leader in the development of IPv6 so consumers can feel confident that home networking products from Cisco will provide top line performance now as well as providing a foundation for the future.
Now is the time to formulate an IPv6 transition strategy for your home network. Cisco recommends a three phase transition strategy:
- Preserve your current investments in IPv4 as you transition over to IPv6 supported products.
- Prepare – Cisco Linksys home networking products provide native support for IPv6 as well as IPv4, ensuring your network is ready for the next generation of technologies.
- Prosper – Take advantage of the next generation Internet at home which includes new applications incorporating video, mobility, energy management and cloud services providing for a better home networking experience.
We are introducing native IPv6 capability into the high end home networking product first, verifying its functionality, proving its stability, and then planning to reuse the base code into the other select Linksys products. While many of the base IPv6 specifications have been available for years, the IETF published RFC 6204 which defines the basic requirements for an IPv6 home router as recently as April 2011. IP is one of the most important protocols to the Internet, and IPv6 is the biggest change in IP in over 30 years. We want to be careful that the implementations we ship work well and adhere to the latest standards so that we do not hinder the adoption of IPv6 by content providers and ISPs.
Simply because there is not a widely deployed end to end IPv6 network yet (even though there are regional deployments). There are four basic areas where IPv6 support is required for the home:
- Endpoint devices (e.g., PCs, phones, tablets, etc.)
- A v6 broadband access network
- A v6 Internet (including websites with content)
- Home routers
Without all four areas, IPv6 is likely not to be used. To date, endpoint devices represent the bulk of IPv6 deployment. Home routers and Internet are following quickly with IPv6 capability. Broadband access networks will be the last to mass deploy IPv6 services (even though there are significant IPv6 deployments from major service providers available now).
The latest firmware for the Linksys E4200 is now available for download at our website: http://homesupport.cisco.com/en-us/wireless/linksys/E4200 and then going to the Download tab and then select hardware version 1.
Also note we have added some additional features in this firmware release including:
- Support of USB printer connected to the router’s USB port, so that a user may send a print job to the printer via the local area network. ** This feature requires Cisco connect software v1.4 or later which is also available on the same download page as described above **
- Added support of Native IPv6 and 6rd tunnel Internet connections
- Added support of bridge mode
- Prevented devices on the guest network to access any private IP address
IPV6 support will be available in other Linksys E-Series in the coming months.
