101  Main Area and Open Discussion / Living Room / Re: Expanding WiFi coverage in difficult buildings on: September 27, 2013, 07:13:45 AM
It is a collection of old adjoining stone built buildings that have been knocked together. Consequently there are thick walls throughout, floors are on different levels (and sometimes at different angles), it is multistorey (3 I think in total but it might be 3.5 - with varying levels).

At the moment it has old mains electrical wiring - presumably using different ring mains inherited from when it was different buildings because mains networking only works very sporadically in parts of the building so presumably it can't get from one ring to the next.

There is no network cabling at all in the building. Basically they have a telephone line bringing in an ADSL signal to their private quarters - a wireless router modem (netgear I think - can't remember the model - but IIRC it is 54g - which doesn't help*). I installed an expander in their cafe area which gives wifi coverage in the cafe and to the rooms on the floor above.

Customers have been complaining about lack of wifi coverage in the bedrooms.

My solution would be to run ethernet cabling to a number of parts of the building from the router and then put wifi expanders on the end but I am not sure how easy or attractive the cabling would be because of the nature of the walls and multiple levels (nothing is flat!) and I am not sure they want to pay for the time.

I suppose an alternative solution would be to run ethernet through a window externally to the roof space and put expanders above the upper rooms.

Whatever happens I think it is going to need a fair amount of time, effort and gear to get full coverage and from my last visit I guess they want to do it on the cheap!


*Update - it is a Netgear N300 Wireless N adsl2 modem/router
102  Main Area and Open Discussion / Living Room / Expanding WiFi coverage in difficult buildings on: September 27, 2013, 06:05:56 AM
A couple of years ago I installed some wifi expanders in a local hotel. They worked but were not brilliant and only provided coverage for parts of the building.

The building is a ramshackle amalgam of very old buildings with thick stone walls internally and externally, on mutliple levels and multiple floors so lines of sight are difficult and wall are thick and difficult to drill.

The problems are the main telephone socket and router are situated away from most of the guests parts of the building on the ground floor.

They don't want the mess or to spend a fortune on having ethernet cables installed and because of the history of the wiring mains networking only works in parts of the building.

Anyone got any other ideas on how to expand wifi coverage to the whole building and get good quality in awkward buildings?

David Omand is visiting professor in the War Studies Department of King's College London and a former director of GCHQ, permanent secretary of the Home Office and UK security and intelligence co-ordinator. He is author of Securing the State

So not at all biassed in his views ...

Great discussion below the article by the way ...

The questions I suppose I am asking is:

1) How many games on Steam actually work on Linux?

2) Do you get a Linux copy if you bought a Windows copy (it doesn't always seem to follow with Mac versions -even Valve titles)

If you want to decamp from MS how many games do you get to keep?  undecided

My prediction for the next "security" feature is that we'll see "retina scans" or something else with the same results.

Yes - either that or class actions for laser burns and blindness! Bad enough when an optician shines things in your eye - don't want tech companies poking about!

OK - not really a surprise but the iPhone 5S fingerprint reader is not proving tough to be cracked.

Who ever thought it would be - its a scanner for heavens sake so if you can find something to scan (like a residual finger print) and perform a pretty trivial photoshop operation you have something to unlock a phone and read your partners secret sexts.

Did anyone really think this was secure technology? I cannot for the life of me understand why anyone argued this technology was revolutionary (apart from Apple's usual marketing hype and the fanboys brain dead response) - it has been around for years on cheap domestic laptops from a number of manufacturers (not that I have EVER seen anyone actually use it),

Sheesh ...

Further details on Gizmodo - and probably half the internet by the time you see this.

How do you lose focus on the start menu - just press the windows key on the keyboard.

Personally I have given up using any of the alternatives - I really like X1 but had lots of problems with it - especially in the days I used Outlook. I couldn't definitively prove it but I seemed to suffer a lot with corrupted PST files when it was installed and it magically resolved when I got rid of it.
115  Main Area and Open Discussion / Living Room / Re: Kiss Encryption Goodbye... :* on: September 06, 2013, 06:44:11 PM
I'd say the most positive aspect of this whole affair is that it should lead to big improvements in encryption in the future.

Trouble is things will get tougher but no system is unbreakable - just look at all the unbreakable codes in history!

OK you will need machines to do the breaking, and if quantum encryption ever happens it is going to be exponentially harder to crack - but what's the bet that long before it gets too hard to crack in a reasonable time scale laws will be passed to prevent 'too difficult' encryption being used or forced to include a 'security' backdoor.

The trouble is the US wields too much power and the powers that be just aren't that bright and so are easily manipulated. The rest of the world is just scared of what the US might do next. The 'special relationship' enjoyed (until recently) by the UK is truly Etonian in nature (if you take my meaning - if not someone else can post a graphic image).

I am the enemy and I am really pissed ...

Democracy - F****

As I UK citizen I also find it amusing that apparently GCHQ have a similar project (though given the UK don't seem to be able to set up any government IT systems that aren't obsolete before they get them working I am not losing any sleep). Also we don't have a constitution .... doesn't the US have some sort of paper and isn't there some sort of vague provision in there for an individuals right to a private life?

Thanks guys ... currently the system is stripped down to monitor, keyboard and mouse ... otherwise nothing plugged in and all components are Dell factory components.

Must admit I thought about the PSU and also if it was something environmental. I suppose something could have shaken loose when they drove it home too.

120  Main Area and Open Discussion / Living Room / Nonplussed - Windows 7 random BSODS on: August 26, 2013, 11:02:56 AM
Totally confused ... asked to fix a Dell computer which is constantly crashing with BSODS and pretty randomly.

It is a Dell desktop running Windows 7 x64.

Tried all the usual things and gave up and reinstalled the factory image. Everything seemed OK but next day the BSODS started again.

Had the computer in my house:

1) Reinstalled factory image again
2) Removed crapware/ Norton etc.
3) Updated from Windows update and all drivers/BIOS/software updates recommended by Dell
4) Installed MSE  and other common tools
5) Ran stress tests and memory tests for 48 hours.
6) Produced Image Backup of system

No logged errors and no BSODS throughout.

Took it back to owner and BSODS start again almost immediately.

Removed everything except screen keyboard and mouse and BSOS continue to appear at random.

Anyone got any ideas?

The commonest STOP codes are 0x1e, 0x7d and 0x3b but they all seem to be random. Most hint at driver issues but they are factory drivers and don't seem to cause issues in my house. All very odd!

This is rather long, so I won't post a quote, but it's a list of non-stop surveillance insanity:

This says it all:

Former U.S. President Jimmy Carter … in the wake of the NSA spying scandal criticized the American political system. “America has no functioning democracy,” Carter said Tuesday at a meeting of the “Atlantic Bridge” in Atlanta.

122  Main Area and Open Discussion / Living Room / Re: Edward Snowden's Email Provider Shut Down Rather Than Comply With Feds on: August 09, 2013, 03:46:40 PM
Lavabit was MY email provider.  I used it because they were a small, relatively unknown email provider (read: smaller target), they used Linux servers (gotta support the flock smiley ), but more importantly, they kept your email encrypted, with no master key.  Only YOU could read your email.  Ever.  

Not strictly true - unless all you senders and recipients also use the same service and you can guarantee end to end encryption (with methods the government don't have backdoors into - I suspect they can get into most of them) your email can be read on the servers of people who write to you and who receive emails from you. OK it would make life a bit more difficult but really it is just processing time if they take an interest. I would guess using encryption is likely to make them keener to read your stuff.

The UK has an interesting policy - it is illegal to use encrypted mail - you can use encryption for transport but not on the servers. GCHQ has to be able to read all your email - they haven't enough to do with real terrorism.

Haven't dared to weigh myself but my trousers are hanging looser so I am pleased (and my cello playing is improving).
