LAN verses WAN port, what is the difference?

The recent connection to fixed-wireless nbn, .. bring attention to this question, what is the difference? – Asking the Internet this question duckduckgo search.?

SOME BASICs – LANs tend to use Ethernet and Token Ring, WANs use technologies like MPLS, ATM, Frame Relay and X.25 for connectivity over longer distances.

The links provided compare important differences in the hardware, and describe the protocols used within ‘a network‘.

This Router_vs_Switch comparision provide useful insight – QUOTE; – “Routers connect two or more logical subnets, which do not necessarily map one-to-one to the physical interfaces of the router. The term layer 3 switch often is used interchangeably with router, but switch is really a general term without a rigorous technical definition. In marketing usage, it is generally optimized for Ethernet LAN interfaces and may not have other physical interface types.” [End quote]

The osi model(s) will describe the Router as Network Layer 3 devices, and a Switch as a Data Link Layer. Network switches operate at Layer 2 of the OSI model.

Support Ends April 8 2014

Microsoft Support for XP ends when? – April 8 2014

TR article, Windows XP: If it ain’t broke…

[Quote] While many IT Pros view an option to stay with XP as “free” when couched against the cost of a major OS upgrade, self-supporting the platform will incur a definite and rapidly increasing cost once Microsoft support ends. [End Quote]

Danger RED signals, imminent failure.

60GHz Wi-Fi

Article for later reference,

Topic, 60GHz Wi-Fi

802.11ac is not ratified yet?

[Quote] Most consumers are familiar with IEEE wireless-networking standards because they have experience with all the earlier ones, namely IEEE 802.11a, b, g, and n (802.11ac will be ratified in early 2014). [End Quote]

WiFi network error – (Access Denied)

PROBLEM; – unable to access shares, via “Start | Run | \\T60”

It has been confirmed that a “Blank-Password Is-Not-Allowed“. (ie, check gpedit.msc)

SEARCH; – access the group policy editor on XP?

#1: –

#2: –

After setting the local password, the access IS allowed.


An extra note; – The Shared Documents folder is a specialty folder XP creates for all local users to gain access to documents which have been placed in it or one of its subfolders. Shared Documents and its subfolders are located in C:\Documents and Settings\All Users, (THIS, is the directory that is being $hared)

Network Timeouts

*HERE* – is a nice description (as understood by an ordinary human) – of what might be happening with network connection, ..

NETWORKING TIP – (As published apc magazine, september 2007) –


Windows Server and Windows XP have difficulty handling connections to network shares
that no longer exist. This can be simply illustrated in the following way, Start a
command shell in Windows XP (Start > Run > cmd) and enter ‘net view \\noone’ (can be
any unavailable resource) at the command line. The Windows kernel will pause while the
I/O subsystem searches for the resource and Windows will appear to pause. Depending on
your network, this pause can be lengthy, especially if you have numerous servers. The
inability of Windows to overcome this comman problem is also evident when searching for
files in popular applications such as Office. Attempting to open a document on a share that is no longer available will cause Word or Excel to hang while the I/O subsystem attempts to find the share. Compare this with Windows Vista. Opening a command shell in Vista (Start > cmd) and attempting to connect to ‘\\noone’ again produces a pause while the I/O searches for the resource. In Vista, however, pressing Ctrl+C causes the process to terminate and return control to Explorer.

* Network Timeouts - XP and Vista *

Similarly, in all versions of Office you may notice that the Cancel button is now available when searching for a document residing on a network share. System administrators, who are familair with hundreds of helpdesk calls produced by users vainly searching for shares on a server that crashed last night (and is causing Office to hang while XP attempts to synchronise with the non-existent server), will sleep more peacefully in their beds.

slmgr -rearm

Command slmgr -rearm
Search slmgr -rearm

This command allow the demo / trial version of windows 7  to be reset, giving you another 30 days. This action can be performed four (4) times.

As part of deployment, many enterprise customers set up the Key Management Service (KMS) to enable activation of Windows in their environment.

slmgr -rearm 

Microsoft Technet: –  KMS Overview – (Key Management Service)
Let’s start with a quick refresher on KMS activation. KMS is a client – server model. It is conceptually similar to DHCP. Instead of handing out IP addresses to clients on their request, KMS enables product activation. KMS is also a renewal model, with the clients attempting to reactivate on a regular interval. There are two roles: the KMS host and the KMS client.

*Hello Ralp*

In October 2008 the last thing you wanted to do was go shopping for stocks.

Lehman Brothers had just gone bust. The global credit system was at a standstill. Banks wouldn’t lend to each other, let alone businesses. The ASX shed 25% of its entire value in a single month.

Chipset RTD 1186 ~ (As installed on 3D Android Player)

This chipset RTD1186 is used on a multitude of devices –
google-image-search RTD1186

This aspect (ie, being installed into a "multitude-of-devices")
of said device, .. makes it nearly impossible to FIND specific
instructions related to "network-connectivity" - 

Seems like nobody could possibly have a problem, ..
No-name / unbranded (except for the Android-label)
Tech-support is non-existent - hence there is no problem.

~ 3D + Android 1080P Full HD Network DLNA MKV Bluray ISO Media Player Realtek 1186 ~

This chipset RTD 1186 DD can be found on the Realtek Digital Home Center

WHAT IS WORKING? – (aspect = provide network access)
Ping the device via IP-address? – YES
Access via windows shell? (ie, run | \\m) – NO
Access via browser? (ie, – NO
Tried the “Auto-configure? – YES, but that did not work (so – NO, it did not work)
Tried Manual configure? – YES, but that did not work (Again – NO, it did not work)

I am able to access the media player via network (windows 7)

Start > Run > \\  It works in that manner only, ..
I may find other ways to access this device, …


NOTE; – In the screen-dump above, .. a 4GB usb stick is providing the storage / disk-content.

Access to the Hard-disk, via the provided USB-3 cable, – YES – (This works)
Next-step – Allow this device to “Format the Harddisk” – CHECK-AGAIN, (that might work, .. resolve all the issues as the HDD is format NTFS, .. with server 2003 install), or getting another hard-disk, might be the easiest solution, as I dont want THIS HDD formatted yet.


#1: – ~ This site provides useful information, .. in the form of history / evolution of “Media Player Chipsets”.

The next generation of Realtek chipset, the ‘6’ series 1186 was released in early October 2011. This runs at 750Mhz, has HDMI 1.4, is optimised for 3D, and is able to dual boot into Android.

#2: – Device purchased – (still available on ebay)

#3: – upgrade this player to latest firmware for a try: -[141 MiB]-
I have used this firmware update (without ill effect)

Upgrading method:
1. Extract the downloaded zip file and you will get an install.img file
