Recently, my home WiFi router started to fail. I was hesitant to replace it but had no choice. Verizon replaced it for a small fee (it was an upgrade). I then discovered just how connected my relatively unconnected home really is.

Don't forget you can always change the new router's default settings so that it has the same name and password as the old access point.

This is one of the reasons I prefer zigbee solutions. The hub is the only part that needs access to the network and it's probably wired instead of wireless.

Thank you for sharing! Great work and methodology.
This paper addresses the security of Sennheiser DECT Contact Center and Office (CC&O) headsets. It describes the DECT security chain comprised of “Pairing”, “Per Call Authentication” and “Encryption”, which are all part of the standard DECT protocol.
DECT technology has become a popular standard for wireless voice communication. DECT devices are not likely to be affected by other electronic devices and signals because they operate in a separate frequency-band.
In the modern office, employees tend to move around the workplace a lot more freely. Conferences, collaborative groups, flexible seating and working from home require a new level of mobility. Technology has not only changed the behavior and the expectations of the workforce. It is also changing the
This article is a step by step guide on how to create a basic PTP link using Ubiquiti airOS devices. This guide can be used on the following Ubiquiti AirMAX devices. Nanostation, Bullets, AirBridge, Nanobeam, NanoBridge to name a few. Please review all the AirMAX device here.. I will be focusing on the selected part of the diagram below for this guide using two Ubiquiti Nanostation M2's. You can use this setup to create a link between office buildings up to 50miles (depending on the device) 


The factory default IP address for the device is and the subnet mask is (/24) open internet explorer and connect to if you are using one of the latest firmware versions you will be redirected to https and you will see privacy error page
Note: You either need to be in the same IP address range or you would need to change your IP configuration on your PC to static Please follow the quickstart guide from ubiquiti to get the device connected to your PC..

Lets get started.

I am interesting in Ubiquiti and mikrotik Devices do you ?
I recently purchased a Bluetooth headset called the Music Jogger (model BSH10). The control buttons on it look like this:

One of my goals is to use it as the microphone and speakers for Skype calls. In that respect, it works well. However, I also want to be able to answer a Skype call with its Multi-Function Button (MFB), so that I don't have to be sitting at the computer when a call comes in. In that respect, the headset fails.

One possible solution is to configure Skype to answer incoming calls automatically, but I don't like this idea, for two reasons. First, most of the time I am at my computer. In those cases, I may not always want to answer a call – especially when I see CallerID . Second, I may not be at the computer and may not have the headset on, in which case I don't want Skype to answer the call. I could try to remember to enable/disable Skype's automatic answer feature depending on my whereabouts, but that is likely to be error-prone – and a nuisance to boot. The better solution is to configure the MFB to answer a call. Fortunately, there's a way to do this easily – and with free software.

The solution presented in this article should work on many Bluetooth headsets. For example, here's another one from Kinivo (model BTH220) with similar controls (excellent headset – I own this one, too):

Hi Christos,
Thanks for joining Experts Exchange today, reading and endorsing my article, and letting us know that the method works with Skype for Business 2016. Thanks, too, for the link to your Bluetooth headset and for sharing your working AutoHotkey code. Great to have a new contributor to our Experts Exchange community...welcome aboard! Regards, Joe
This article is split into background info to start and actual review at bottom:

Some time ago I wanted to sell a system with both wired and wireless capability but at minimum expense.  Having visited my trusted online auction I was pleasantly surprised to find a card that met my requirements with the bonus that it supported N-draft wireless protocol.

EDUP 802.11B/G 54Mbps PCI Wireless Wifi Card

The problems arose when I tried to install this device on an XP 64-bit system.  The supplied drivers were 32-bit only.  Not deterred by this, I went looking for the company's website but could only find resellers (such as this one).  In addition, after looking through the forums, it seemed I was not alone.

It took me some time but using "Unknown Devices" I was able to ascertain that the recognised chipset was based on an Atheros AR5212 (also shows up on Atheros website under the AR50002 or AR5000x range).  However Atheros do not provide product drivers for their wireless, at least none that I could find.  After some searching I found suitable drivers from an unofficial Czech website.  

For information only: http://www.atheros.cz/

Now for the review and nitty gritty:


The actual product was cheap and "looked" new in OEM packaging I.E. no box.  The product installed with the proper drivers for 64-bit no problem.  The 32-bit Atheros …
Last Mile Wireless
The term last mile wireless is a bit deceptive as it can be much more than a mile. It is also called WiMax and 802.16. It generally refers to relatively short distance point-to-point / point-to-multipoint secure wireless connections between buildings and/or a service provider and their customers.

In this article I will be focusing on building to building connections.

Many businesses have run into the issue of having more than one building or facility that needs to be connected on the same network. The distances covered are more than a standard access point can handle and hardwiring is expensive and sometimes impossible. This is when last mile wireless becomes attractive.

Point-to-point vs Point-to-multipoint
A lot of the lower end and consumer WiMax stuff is straight point-to-point. That makes for a nice cheap plug & play set up, that is their big selling point.

Point-to-multipoint means you have to set one up as the base station and the other(s) to being subscriber units. Sometimes the differing units are identical and can be switched to one or the other with a relatively simple web interface. This makes for much easier future expansion and you can have an extra unit on hand in case one end or the other goes bad.

No one likes to think of equipment failure, but a wise administrator takes this into consideration before the purchase order / requisition is even written. It only makes sense to choose a …

This is the kind of 'how-to' stuff I like to see on EE. If you get a chance, I'd like to know some details of the equipment you ended up using.
I tend to buy the basic wireless routers (Linksys/Netgear) and they don't really have the punch for bigger houses/buildings.

Thank you.

I have had so many issues with my Vodafone 3G card (Novatel Merlin u630, provided by French carrier SFR) on Windows XP laptops that I thought I would create an help page for other users (I solved the issues).

First issue, with my IBM/Lenovo laptop Thinkpad Z60m

It did not work, the "Novatel Wireless UMTS Modem Secondary Port" device always appeared with a yellow mark.

Hopefully, I found some indications:
1. Insert the Merlin into the PC card slot.
2. Go to Device Manager. Start > Control Panel > System > Hardware > Device Manager.
3. Expand the Modems, the Multifunction adapters and the Ports category.
4. Select the Novatel Wireless UMTS Modem Parent under the Multifunction adapters category.
5. Right click and choose properties from the available menu.
6. Choose the resources tab.
7. Uncheck “Use automatic settings” to manually change the resource settings.
8. In the “Settings based on” drop down menu, choose a configuration that will eliminate the
error code. Usually, configuration 0004 or 0005 will work.
9. Choose OK and YES to further dialog windows.
10. Verify that there are no markings on Modems, Multifunction adapters or Port devices in Device Manager.

I found these hints on this page:

This made the card work in my Thinkpad...

Then, my company was acquired by another company and I got an HP Compaq 8510w mobile workstation.

This article describes how to perform a hard reset on your router. Usually this is most-useful on wireless routers, but the same concept applies to nearly all home/SOHO routers. This process will return the router to factory defaults, so record your settings first because you'll need to re-enter them when the procedure is finished. In most cases all people need to do is configure the LAN IP, and the wireless security and they're done. If you have extra firewall rules, port forwarding, et al customizations made, you should probably use the built in administration tools to backup your settings and then simply import them again afterwards.

The process is essentially holding the reset switch in for 90 seconds while removing its power for the middle 30-second block.

1. Disconnect All Cables

Unplug all the network cables from the router before performing this procedure. Label them if necessary (at least mark the cable plugged into the Internet/WAN port), so you can return them to the same ports afterward.

2. Depress Reset Switch

The reset switch/button is usually on the back. Using a straightened paper clip or a toothpick with the points blunted, press and hold the reset switch. Note the time, or counting works too.

3. Remove Power

After 30-seconds, while continuing to hold in the reset switch, either turn off the power strip the router's wall wart is plugged into, or just pull the adapter plug out of the back of the router. Leave it powered off for 30 seconds.

How do you know your method can clear NVRAM ? and regular 10 to 15-second single reset often does NOT clear those variables.any proof to  support  your saying?

I know it resets the NVRAM simply because it is reset, every setting is factorry default, everything i changed on it, and stuff is back to the way it came from the store.
