Automatic Metric Solves Wireless and Ethernet Network Issues

Automatic Metric: Windows 7 Laptop Will Only Connect to Huawei E5372 on UK Three Network, OR the Wired Home Network

Windows 8 Computers Work Fine Though!

Connecting Win7 to wireless and ethernet networks simultaneously

Problem link is shown in red

Automatic Metric is the place to be!

I have two networks essentially:

  • The “normal” wired network (gigabyte ethernet) that links all computers and printers through the Cisco Router.
  • The temporary mobile network that allows the PCs to connect to the internet while we are in temporary accommodation.  It’s a Huawei E5372.

The Issue

After setting up WiFi on the PCs, access to the Ethernet network disappeared – but only for the Windows 7 computer!!!

This meant that file transfers, backup etc between the machines, ceased, as well as access to the wired printer.   The printer worked fine when connected through its USB connection.  It has no WiFi.

In the same way, disconnecting the wireless enabled connectivity to the wired home network (Ethernet).

I searched and many forums had similar “fixes”, none of which worked. e.g.

  • Remove IPv6 leaving just IPv4 on the network adapters.
  • Remove network devices completely and re-install.
  • Try new or updated drivers.
  • Reboot each time.

However, two very small items appeared and worked for me!!  They are network settings, deeply buried and that I’ve never set before.

The Fix(es)

It’s the same in both Win 7 & 8.  Maybe even Vista, but as we know, Vista Means Death.  I did two places that got the Win7 machine to connect to the web through the Mobile WiFi dongle and to the home, wired and routed, network.

  1. Adapters and Bindings
  2. Automatic Metric

So Adapters and Bindings…

Network Adapters And Bindings

Network Adapters And Bindings (as seen in Win8)

  • Network and Sharing Center
  • Change Adapter Settings
  • Advanced on the menu. (Alt+N)
  • Advanced Settings
  • Adapters and Bindings tab
  • Set WiFi at the top

Oh Woe Is Me Again!

At this point, connectivity was still not restored, but it was an interesting setting, totally hidden in Win8!

 And Automatic Metric…

This is the killer setting that worked!!!  You need to do this twice:

  1. once for the Wireless network adapter
  2. and again for the wired Ethernet adapter
Here’s how
  • Network and Sharing Center
  • Network Adapter Wireless - Automatic Metric

    Network Adapter Wireless (Win 7)

    Click the first adapter, the one I need windows to use first.  i.e. The Wireless adapter.

  • Click Properties
  • Scroll down to “Internet Protocol Version 4 (TCP/IPv4) and select it.
  • Click Properties
  • Click Advanced
  • Uncheck Automatic Metric and put a low number (say 1) in the “Interface Metric” box
  • Click OK to save the settings changes.

Now do the second, Ethernet adapter.  Follow the previous method.  However, this time,

  • Network Adapter Ethernet - Automatic Metric

    Network Adapter Ethernet (Win 7)

    Uncheck Automatic Metric and put a high number (say 5000) in the “Interface Metric” box

  • Click OK to save the settings changes.

Conclusion

One commenter on the forum I saw (link to be done) said that just setting the order to 1,2,3 etc wasn’t sufficient.  Setting a large gap between interface metrics did the trick, which is what I did.

What Is Automatic/Interface Metric?

Well, you can do this search, or probably the best answer comes from Microsoft, here.

It sets the priority of network interface access, lowest number first, on an individual machine.

In my case, weirdly, the Windows 8 machines had no difficulty.  The single Windows 7 laptop fell over and caused me immense hair loss until I stumbled across the settings which I have never, ever touched in 17 years of computing and the web!

Virtual Box Running 32 bit Win7 inside 64 bit Win7

Introduction

These shots are primarily for the benefit of my friend.

Virtual Box

Sun’s (now Oracle’s) VirtualBox application allows computer users to run a variety of Operating Systems (OS) on virtually any computer operating system.  This is the VirtualBox homepage.

For example:

  • Windows XP on Mac
  • Solaris on Windows XP
  • Windows 7 32-bit on Windows 7 64-bit

This latter example is actually the system that I use to connect to my remote work computing system.  (We use a Citrix client which will not upgrade to 64 bit, hence the necessity of running the Citrix program in a 32-bit environment)

The two shots below show Task Manger’s “performance” tab in the two systems.  I’m showing this to demonstrate that upping the memory to 12Gb has left Windows the opportunity of using as much memory as it feels, and by not using the pagefile (much, if at all) it’s very fluid in operation now.

This screenshot shows Task Manager in the host Win7-64 system with its 12Gb of memory and four processor cores.

Win64 Processes

This screenshot shows Task Manager in the virtual Win7-32 system running inside a VirtualBox image with the 4Gb of memory and four virtual processor cores that I allocated to it.

Win32 Processes

This screenshot below shows the view across all three screens that I use.

Windows 7 across 3 screens

In the shot you’ll see that I’ve set the VirtualBox image to run full screen on the right-hand monitor.  I’ve chosen a different background to emphasise this.

A notable feature of VirtualBox is that I have set the mouse cursor to float seamlessly between the two environments.

Previously, I’ve tried installs of several Linux flavours into their own virtual image areas.  These are all removed now, but previously I had several running concurrently – I wish I’d taken a screenshot at that time.  To demonstrate the capabilities of VirtualBox, I once had running concurrently these various operating systems inside my Win7 64-bit host:

  • Windows 7-32 bit
  • Windows XP version one
  • Windows XP version two
  • Ubuntu 10.1
  • Mandriva 10
  • Suse 11
  • Fedora

To enable this all to run in only 4Gb of memory I assigned about 300Mb to each image.  They all worked “out of the box”!

In the Russian Dolls virtual world of my PC (I’ve currently upgraded to a AMD Phenom II 4x core 955 Black Edition which now allows me to run at least six Operating Systems (OS) concurrently – at the last count!), I have a Remote Desktop Connection (RDC) inside two virtual versions of Windows XP connected to work with drives and printers mapped every which way and also via a Virtual Private Network (VPN).

CPU-Z CPU

I’m running Windows 7 and the two virtualization programs are Windows Virtual PC (using XPMode) and the much better, Sun VirtualBox.  It’s hard to keep track of it, what’s real and what’s not, if you see what I mean…?

Q. So what?  I hear you ask…

Well I got a Google Alert today which flagged a mysterious call to vote.  It pointed here:

Vote Crawling Chaos for Congress in Jeollabuk-do! (click)

Intrigued, I followed, and you can too….

Vote Crawling Chaos for Jeollabuk-do and Imperial Sun party for eJapan!

Vote Crawling Chaos for Jeollabuk-do and Imperial Sun party for eJapan!

A. It’s a virtual world where people can virtually vote for virtual political parties in the constructed world called ERepublik (100% free and only minutes to sign up, it says).  All the papers have been talking about it and so far it appears that ~10k folks from each actual country are signed up.

Me? The real world is virtually enough.  It’s more like The Matrix by the minute!  So, welcome, to the real world!

– and vote for Crawling Chaos! ha ha.

Of course, my extra computing power now allows me to see the background animation for the Crawling Chaos website.  Wahay!  It’s a slow moving background colour change, which, bizarrely, is something I planned but never implemented as subtle room lighting when Crawling Chaos were in The Pits Studio.

Adobe Acrobat Turn-Off!

Strangely post on April 30th, 2009
Posted in Technology Tags: , , , , , , , , , , , , , , , , , , ,

Introduction

A few month’s back the Adobe Acrobat Reader landed itself in doo-doo with some Javascript security worries.  Adobe were slow off the mark informing their customers (like me) what to do.  So it was the blogs that provided the answer:

Turn off Javascript

Unfortunately, this wasn’t enough.  After a week a huge patch was issued.

Solution by Realisation

At this time I’d become increasingly frustrated with the program.  All it had to do was read pdf files, (an invention of Adobe), which since 1997 when I got my first PC, it’s managed to do, getting slower and slower at it as the different versions came out and yet mysteriously, processor speeds have increased dramatically.

My first processor was a 100MHz K5.  Now it’s a (now obsolete) Athlon64, 3700+ using the single, but extremely fast,  San Diego core.

Similarly with the annoying unwarranted updates control it insists on installing into it’s vast bulk.  Vast? Yes vast.  Last time I looked the bugger was taking up 221Mb on my hard drive just to read the odd PDF!

So that’s when I not only turned off Javascript.  I turned off the Adobe Reader!!!

I’ve never looked back.  I tried the Foxit Reader.  It installs in a jiffy, loads almost instantaneously and does everything that a PDF file reader should do – that is, it reads PDF files!    (I wanted to say ‘period’ there but I put an exclamation mark for effect – geddit!)

So that’s what I advise everyone to do.  Ditch the montrosity and try something else.  Get back to fast computing.  I’m going to give some of the Open Source readers a go next from this list here: http://pdfreaders.org/

Real World Computing Experience

The Triumph of Wishful Thinking over Common Sense

The recent previews of the Microsoft Vista replacement with it’s unreliable “hands on” dragging experience (http://news.bbc.co.uk/1/hi/technology/7695933.stm) are another reminder that desires aren’t always satisfied and that designers don’t always design what people actually want for their daily work.

PCPro Magazine have duplicated the recently banned Apple iPhone advert to show the machine working in the real world – not some advertising paradise.  See here:  http://www.alphr.com/news/239556

The real world video shows the “amazing” window dragging and resizing to be crap. (the slow download speed is another issue for which they’ve rightly been slammed ). In a real office, be it graphics, CAD, code or clerical, no-one will ever get anything done on a system like that.  Apart from the obvious “un-stickiness”, there is no fine control over graphical elements.  To replicate what’s possible using a mouse or pen-tablet we’ll need fingers like a butterfly’s proboscis, not the current appendages we have!

So recent remarks about the imminent death of the mouse I see as very wide of the mark..  Fortunately, I’m not in a club of one; say here and here for instance!

Truly, it’s style and marketing before substance, a solution looking for a problem.
