Cisco Warns Of Vulnerabilities In WLAN Controller Lines

Cisco this week issued a security advisory pertaining to several vulnerabilities for its wireless LAN controllers, including two denial of service (DoS) vulnerabilities, three privilege escalation vulnerabilities and two access control list (ACL) bypass vulnerabilities.

Cisco lists eight product lines affected by at least one of the stated vulnerabilities, including Cisco 2000, 2100, 4100, 4400 and 5500 series wireless LAN controllers, Cisco Wireless Services Modules, Cisco wireless LAN controller modules for Integrated Services Routers, and Cisco Catalyst 3750G integrated wireless LAN controllers.

4ipnet NetTicketGen Network Ticket Generator Set

As Internet usage continues to become more mobile, customers have an increasing expectation for wireless Internet access at public locations, such as in coffee shops, restaurants, hotel lobbies, convention centers or airport terminals. Whether you are thinking of running a hotspot for free or for a fee, you will need a hotspot management system to maintain quality of service for your customers, eliminate free-riders, and keep your network secure.

4ipnet NetTicketGen Network Ticket Generator Set, SDS100 Smart Device Server and PRT100 POS Printer, is able to provide the easy hotspot solution that turns your venue instantly into a managed, branded and moneymaking hotspot.

SDS100 Device Server and PRT100 POS Printer lead a simpler way to serve the hotspot area. Designed to support account generation, SDS100 Device Server triggers the built-in On-Demand billing plan(s) inside 4ipnet WHG Controllers or HSG Gateways and then prints account tickets with the PRT100 POS Printer. Each WHG Controller or HSG Gateway can simultaneously support multiple NetTicketGen Network Ticket Generator Sets via the network. The on-demand accounts can be generated at the counter by the hotspot owner by pressing a few buttons on the SDS100 Device Server to print account tickets. All PRT100 POS Printers connect directly to SDS100 Device Server with serial port (in RS-232) and SDS100 has a standard TCP/IP (in RJ-45) interface, so it is easy for NetTicketGen Network Ticket Generator Set to join your network!

How it Works:
Price Hot Spot access by:
*Usage, Date Volume, Duration, Purchase
*Press buttons on Ticket Generator
*Print an Account Ticket

WPA2 vulnerability “Hole 182” and solutions

Airtight recently announced a vulnerability in the WPA2 Enterprise standard that can allow an authorized user to spoof packets on the network and then perform man-in-the-middle attacks. This attack has been designated Hole 182.

Simple WPA2 security fix: Enable client isolation on your wireless network. Client isolation blocks two wireless clients attached to the same access point from talking with each other, which is critical to the success of this attack.

Hospitality Wireless: SF WiFi delivers complete wireless coverage

Whether providing the traveler a comfortable room, television entertainment, or continental breakfast, our clients consider great hospitality is paramount. A recent client, The Majestic Hotel of San Francisco, offers the gracious traditions of yesteryear and today. They realized one of the essentials of the modern traveler is having seamless, reliable, and secure access to the Internet but with the present down economy the hotelier required a wireless solution which didn’t exceed their budget.

 The Majestic Hotel contacted us about installing a more powerful and efficient wireless network than their existing system. They had been using a legacy wireless solution that had many issues including proper signal coverage. As a result, guests’ computers were constantly dropping off the Internet. This was causing the hotel to lose guests and lose revenue so they contacted SF WiFi to propose a guest wireless network solution for the 33,000 square foot property and we were awarded the project.

Hotel Overview

The Hotel Majestic was constructed in 1902 and is San Francisco’s oldest continuously operating hotel. With distinctive French bay windows, Edwardian styling with vintage architectural details and adorned with French and English antiques. The Majestic not only offers guest the gracious traditions of yesteryear but also provides the guest with all the modern essentials of today.

 Hotel Specs: The property consists of 5 floors, 58 rooms, café bar and restaurant and 2 meeting rooms. Guests were complaining that the wireless coverage was limited, connections and performance was erratic. Adding additional Wi-Fi access points (APs) was not an option because there was no way to extend ethernet cabling throughout the property. The Majestic needed an innovative solution that would satisfy customers without disrupting business or breaking their capital budget.

 SF WiFi gets the call – Project Requirements:

  • Wireless coverage throughout the entire hotel
  • Minimize the number of access points
  • Minimize, mitigate RF interference
  • Install AP’s where Ethernet can’t reach
  • Centralized and simplified management
  • Reduce install times
  • Self-configuring, self-tuning adaptive wireless
  • Reliable and stable with no support calls
  • Consistent performance

SF WiFi solution:

To work around and to minimize the need for additional ethernet cabling we designed a wireless mesh network. Under normal circumstances ethernet cabling is required for all conventional wireless equipment. The SF WiFi design solution implements a WLAN managed mesh network to extend wireless coverage into difficult areas. This design limited the amount of cable required, reduced costs and simplified the installation.   

 

Benefits:

  • Reduced capital costs by eliminating the need to run ethernet
  • Dependable Wi-Fi signal quality
  • Single Wi-Fi solution for entire hotel
  • Mesh design simplified AP placement (product feature)
  • Automatic interference avoidance (product feature)
  • Automatic failover and resiliency (product feature)
  • Wi-Fi coverage with fewer APs (product feature)
  • Utilized Power over Ethernet
  • One third the cost of “other” wireless product solutions

Apple offers free bumper to resolve iPhone 4 issues

Anyone who buys an iPhone 4 through Sept. 30 will get a free “bumper,” a rubber-and-plastic band that wraps around the phone. Customers who have already purchased a bumper will get a refund. AT&T Inc. (T) subscribers who want to return the device can get a full refund and get out of their contracts without penalties.

An AT&T spokesman said the company supports Apple’s move to provide a free bumper and said it would waive the restocking fees for returned iPhone 4s.

Capacity and Growth

Went to a party on Saturday night. The conversations ranged from the World Cup, LeBron James, and when’s dinner. As dinner became delayed the Apple devices came out. iPhones 3G, 4G, and iTouch. (I left my iPad at home). I became impressed with a friends tech savvy son “RC” and his knowledge using his iTouch.

RC – A student in junior high – budgeted his hard earned savings and purchased an iTouch. (with some help from the bank of DAD). It goes without saying that RC is a very bright boy who schooled me on the latest game apps. Now I am hooked on Flight Control and Angry Birds. High five buddy!!… or should I say fist bump?  

The evening reminded me that when we design, install a WiFi network, (or any network infrastructure) we must take into account future capacity and room for expansion. With capacity for future mobile devices, with more apps and more users. Network design must choose applications and hardware that will allow the network to grow.

Quick example: Wireless systems that utilize the 5 GHz band (802.11a) for the wireless mesh backhaul. A significant advantage, since the 2.4 GHz band is heavily used to the point of being crowded.
