Welcome to “Wi-Fi Wisdom”! This blog is intended to be a source of tips, advice, reviews and tutorials for anyone looking to get the most out of their wireless network.

Although I am not a ‘techie’ or a ‘computer geek‘ I have been working with computers since the early 1990′s and have lots of experience getting them to do what I want. I have worked with both Windows and Mac computers , as well as dabbled with Linux. I hope to avoid any overt bias to one OS or another but as I use a Mac as my main computer and Windows is the dominant OS on most folks desktops (UNIX is not common in most homes and SME’s), these two will feature more than Linux in my posts.

I will try to avoid any tendency to say Macs are better than Windows computers, even though I truly believe that on the whole they are (the computers as much as the OS). There, I have said it! I promise not to let it stop me pointing out where Macs are deficient or where Windows gets it right. However, as we will be concentrating on wireless networking in this blog, the actual OS is mostly irrelevant. Its will be more about protocols, practical things you can do to improve your wireless network’s performance and issues such as security etc.

Please do leave comments and any links you have found useful. I am only one person and its impossible for me to know everything.

After successfully running a trial at Charing Cross Tube Station, Transport for london has decided to go ahead and commission wi-fi at up to 120 stations across the network in time for the London Olympics in 2012.

The trial was was carried out in partnership with BT Openzone and was enthusiastically received by passengers. Tenders will now go out and the winning bidder chosen by the end of this year.

Research during the trial at Charing Cross Tube station found that over half of LU passengers surveyed felt that access to wi-fi would make their experience of using the Tube better.

In related news, Transport for London (TfL) and the Mayor of London are currently in discussion with mobile phone operators and other suppliers about the potential provision of mobile phone services on the deep Tube network.

Motorola Xoom comes under fire

Motorola Xoom Android TabletIf you are thinking of not buying an iPad then you may be in the market for something like the Motorola Xoom. However, before you hand over your hard-earned cash you may want to read this article by Michael J. Miller, respected blogger at PCMAG – Eight Things to Hate About the Motorola Xoom. In it he shares the things that worry him about the device (already having previously written a similar article about the “8 Things I like about the Motorola Xoom“.

Not wanting to just quote the article verbatim, let’s just say that he basically finds the device is not quite there yet, which says to me that Motorola have made the same mistake that numerous other companies have, they have tried to jump on board of Apple’s bandwagon and rushed out a product that is in no way an equal of the iPad (never mind the soon to be released iPad 2). In particular he points out that there is no Flash capability, only 16 apps are available, some of the phone apps don’t seem to work either and the SD slot isn’t functional.

Anyway, why not read both articles and make up your own mind or go straight to the full review by PCMag.

WiFi Gaming Card Released

Bigfoot Killer WiFi Gaming CardBigfoot Networks are known for their gaming networking kit and today they have announced their latest piece of kit – the Killer Wireless-N Laptop Network Adaptor. Normally we focus on mobile wireless networking and configuring your static network, at home and in the business environment. However, wireless networks are becoming much more common with many homes having several computers on a wireless network. Often these are used for gaming so kit like that which Bigfoot is known for is becoming more popular.

So, what does this ‘killer’ piece of kit have to offer? Bigfoot claims that the Wireless-N offers transfer speeds up to five times faster than those of standard WiFi adaptors. It’s claim is that this will give any gamer using it’s kit an advantage over other players by reducing lag and latency.

To achieve it’s performance, the card uses some clever 802.11n technologies that Bigfoot have developed in-house. The card also comes with the same software that Bigfoot ships with existing networking kit for desktops.

Whether all this adds up to something to write home about is another question. In the past Bigfoot’s claims have come under some criticism for not being backed up by real-world experience. Let us know if you take the plunge and share your experience of putting Bigfoot’s claims to the test.

Features:

• Cutting-Edge 11n Performance – Advanced, dual-band (2.4 GHz and 5 GHz) adapter supports IEEE standards-based 802.11a/b/g/n. Killer Wireless-N 1102 enables PHY rates up to 300 Mbps over 2 stream MIMO and offers up to 5x better latency than the competition.1

• Advanced Stream Detect – Automatically classifies and prioritizes online games, HD video and high quality audio for better quality and fewer interruptions in your online experience.

• Visual Bandwidth Control – See which applications are hogging bandwidth and tune performance for each, so they don’t interfere with your online gameplay or multimedia applications. Download files or watch a video or browse the web simultaneously – it’s all possible now with Visual Bandwidth Control.

• PC Monitor – Monitor and manage the health and performance of your wireless notebook PC with graphical displays, detailed logging and an intuitive user interface.

Note: There are two versions of the card, the 1102 and the 1103.

Malware risk on unsecured WiFi networks

It’s something I have mentioned previously but it’s worth reiterating…. using unsecured WiFi networks put you and your precious data at risk. This is true not just when connecting to such networks via your laptop whilst on the move. It’s just as true when using your smartphone or iPad or iPod Touch, indeed any of the various types of devices that come with a WiFi ability.

“Consumers need to realize that mobiles, whether smartphone or tablet, are mini computers,” said David Gorodyansky, CEO of AnchorFree. “This means all the vulnerabilities of a computer exist, often with a less-protected OS.”

For companies and individuals, smartphone access should be a concern when that access is via unsecured mobile networks. For banks and e-commerce sites in particular, as well as consumers,  security has become much more important now than ever before.

So, what steps can you take to protect yourself? Well, just like when using your normal PC, don’t click on links in unsolicited emails (known as ‘phishing’ emails) and don’t respond to emails that you weren’t expecting, or from sources you hadn’t signed up to and certainly don’t click on links asking you to verify your logon details, in particular ones claiming to be from your bank.

Be wary of emails that come from social networks such as Facebook, MySpace and the likes of Twitter, especially if it’s not from any of your regular contacts. Spam is a real problem at the moment with these and there are numerous scams going around the social networking world at the moment.

It’s good advice to never give out personal information via email, smartphone or on the Web, and always verify independently  any unknown text or email message, game, application or security update.

Don’t logon in the first place to an unsecured network and instead use security all the time, using a VPN to encrypt and secure your browsing.

O2 outlined it’s plans recently to offer seamless, fast and free internet for all, in venues across the country. Here is what it said in it’s Press Release:

“O2 announces it’s plans to deploy a market-changing public Wi-Fi platform in the UK, with the launch of O2 Wifi. O2’s premium hotspots will be managed through partnerships with key venue owners and will be open for all customers to access for free, no matter which mobile or broadband provider they are with. O2 is aiming to create a scaled Wi-Fi platform that will be at least double the number of premium hotspots currently offered by BT Openzone and The Cloud combined by 2013.

It will begin rollout immediately by replacing its existing 450 Cloud hotspots in its retail and office estate. It will continue to extend the reach and scale of O2 Wifi through partnerships with strategic venues, to include shops, restaurants, retail outlets and outdoor and indoor locations across the UK. The O2 Wifi service will address the many shortcomings of current public Wi-Fi offerings by being genuinely free to customers, simple, fast and secure. O2’s mobile expertise and insight, allied with an enhanced quality of network connectivity and strong venue partnerships will now deliver a significantly enhanced user experience.

O2 Wifi will introduce a new level of customer engagement, driving increased value for both the Wi-Fi hosting venue and the user by bringing together O2 Wifi with the capabilities of O2 Media and O2 Money to offer the potential to deliver relevant timely content that customers want in a format that suits them. Access to the hotspots will be through a simple sign-up process and will be free to both O2 and non-O2 mobile customers, providing seamless connectivity to a high quality network. The sign up process will be auto provisioned for all O2 customers with Wi-Fi devices by the end of the year.

All hotspots will be premium public hotspots, as opposed to using residential connections with limited bandwidth. O2 has long been a market-leader in provision of public Wi-Fi services across mobile devices, introducing unlimited Wi-Fi access included in iPhone tariffs over three years ago. Through O2’s partnerships with BT Openzone and The Cloud, adoption and growth of Wi-Fi services has been significant with customers seeing real usage benefits. O2’s New Business Development Director Tim Sefton said: “Building networks is a core capability. We have pioneered the explosion of mobile data over the last three years and know better than anyone where people are accessing data.

O2 Wifi hotspots will bring high quality public Wi-fi access to the majority of mobile users. “Only 20% of people who have access to free public Wi-Fi on O2 tariffs actively use it despite the majority of devices being Wi-Fi enabled. We know that Wi-Fi as a technology has great potential and can be a very fast service, however customers are discouraged by barriers which include complexity in activation, uncertainty of where Wi-Fi is free and the variable quality of the current experience. “O2 is integrating new layers of technology into the existing network to enable a seamless and sustained customer experience. We are technology-agnostic and driven entirely by our customers’ needs. We believe that services should be delivered in the best possible way, across multiple networks, supported by different technologies.” In addition, O2 is increasing investment in its mobile network by 25% in 2011.

These investments will allow O2 to offer customers access to a suite of layered technologies, including 2G, EDGE, 3G, 4G, HSPA+ and Wi-Fi, seamlessly, simply and at speed. These technologies will enable customers to access a new range of ‘smarter’ services and experiences. “

The Future of Wi-Fi

Wi-Fi is growing in popularity, according to the WiFi Alliance (but then it would say that, wouldn’t it!). However, it appears to be the case, with increasing numbers of smartphones coming with built-in Wi-Fi and one only has to think of the iPad and the iPhone sales numbers to realise that there is a growing number of wireless devices out there.

So, what can we expect from our wi-fi in the future? Well, 802.11n is becoming more ubiquitous and now the Wi-Fi industry has its sights set on increasing Wi-Fi throughput and range, with upcoming certification programs for Wi-Fi in the 60 GHz frequency band and with Very High Throughput (VHT) Wi-Fi in 5 GHz.

There is also the introduction of Wi-Fi CERTIFIED Wi-Fi Direct™, a certification program for device-to-device communication without a wireless network or access point. This may well see the death of bluetooth.

Certainly, the rapid growth in wireless devices (device shipments expected to reach two billion by 2015 )  means we all need to think  more about security and avoid using unsecured networks whenever possible. It’s thought that some 400, 000 of the 3.5 million hotspots around the world are unsecured and vulnerable to hacking, so beware.

Seems that not everything is going smoothly for Microsoft, with reports of various problems and mixed reviews for it’s new Windows 7 smartphone devices.

Already, PC giant Dell’s new Windows Phone 7-powered smartphone Venue Pro reportedly has a WiFi glitch. According to the company, a firmware glitch is the culprit behind the connectivity issue faced by some users. Dell, have confimed in the blog that the issue that was reported in blogs like Boy Genius Report and Ubergizmo is indeed genuine. 

HTC Windows 7 handsets have also been reported as experiencing problems with WiFi, atlhough HTC has remained strangely quiet on the front, for now.

Wi-Fi Firesheep Hacking Tool Threat to Public Wi-Fi

Posted on by macficionado

Firesheep is a Firefox add-on that it possible for anyone to hack into open Wi-Fi networks, such as those commonly found in public networks. Written by Eric Butler, it allows you to intercept cookies by Amazon, bit.ly, Facebook, Twitter, CNET, Cisco, Dropbox, Google and numerous others. The technique is known as ‘HTTP session hijacking’ (or ‘sidejacking‘). The programmer also says its easy for any competent programmer to write their own plugins to add to the sites that can be hacked.

The captured cookies contain the login details of the unsuspecting user of the public network and will also display their photo and name in the browser sidebar. By double-clicking on the user you can then login to the site in question, just as if you were the actual user. The potential for anyone to exploit this for nefarious ends is frightening, and should make everyone think twice about using public (open) networks at all.

Butler has said that the only effective way to combat the vulnerability his Firefox web browser add-on Firesheep takes advantage of is for the sites to use full end-to-end encryption, known as HTTPS or SSL but many sites default to the HTTP protocol because it’s quicker.

Although you can download the add-on from eleewhere I am not including any links here to it as I don’t want to encourage such activity.

Google sinks deeper in the mire of its own creation

Posted on by macficionado

Its a while since the fuss over Google’s Street View cars ‘stealing’ wifi details as it cruised by our houses first blew up. We may have forgotten about it but the lawyers haven’t and now Google has come clean. Finally, they have admitted to taking some emails, URLs and passwords during its Street View operation. How many precisely isn’t clear but it means Google is now facing further legal action and in all probability, a hefty fine. hefty by most folk’s measure but in this case it seems the maximum fine could be just £500,000. This is a tiny amount for a company as rich as Google. Admittedly, this is only in the UK but even so, it’s nothing.

The same can’t be said about the negative publicity that Google will receive and its not likely to be the end of the matter either, with other countries legislators looking to fine them too. Some commentators think Google has broken no laws so that no fine is possible. Privacy groups of course have a different view and are calling for Google to be heavily punished.

Whether you believe Google acted in a malicious and illegal manner or that it was an entirely unintentional and accidental error on their part is somewhat irrelevant. What’s important is that if Google can collect private data so easily ( a drive-by snatch ) then how easy can it be for a determined hacker? All this underlines the need for you to have decent security on your wireless network, so make sure you are using WPA2 (and not the easily hacked WEP) security on your network. Otherwise you are asking others to come and steal your private data, possibly your identity and your money sitting in your bank accounts too. You have been warned.
