Setting up multiple WiFi devices

I was recently having connectivity issues at home, with the wireless router being at one end of the flat and the living room right at the other end. Having an ethernet connection in the living room, I decided to add a secondary WiFi and dug up an “old” Netgear wireless AP.

Not wanting to keep switching from Wireless #1 to wireless #2 all the time, depending on which was in closer range, I decided to give the devices the exact same name. Now it doesn’t matter where I am in my flat I am always connected to the same wireless network, and with a 100% strength.  The trick for it to work well is:

  1. Each device has a different IP address within the same subnet
  2. Both devices have the same SSID
  3. Each device broadcast on a different channel
  4. both devices use the same security settings (WPA is safer than WEP) and same access key

IPV4 is almost exhausted.. time for IPV6?


UK or US

According to Vint Cerf, vice-president of Google and the man dubbed “the godfather of the net”, Europe will run out of IPV4 addresses by mid 2011.  It’s time to switch to IPV6.

IPv6 was developed by the Internet Engineering Task Force (IETF), and is described in Internet standard document RFC 2460, published in December 1998. It has the capacity to provide 3.4×1038 IP addresses (around 340 trillion, trillion, trillion), probably making NAT (Network Access Translation) something of the past.

Are network and system administrators ready for the change over? Are SMEs ready for the change over? It’s time for a bit more reading I guess.

Virginmedia has bad customer service

Having had services from Virgin Media before I decide to go back with them for my broadband at my new place. I did that against all the bad comments from others about their bad customer services and slowness in getting your connection setup. Well here is how it went.

  • Called Virgin Media to setup connection..
  • VM: “oh sir we need first month payment up front and we can get you connected”
  • ok Payment made
  • VM: “Now let’s arrange your connection date … I am afraid the earliest available slot is on the 12th of July (in 3 weeks time)”
  • ME: “How come? Can’t you do it sooner….”
  • VM: “I am afraid not”
  • Installation day ( 3 weeks later)
  • VM Engineer: “Sorry mate we cannot connect your cable, it would have to go over someone else’s business sign,we cannot do that”
  • ME (calling VM): “Can I get the account cancelled and upfront payment reimbursed to my card?”
  • VM: “Just hold the line a second.”
  • 15 min later
  • VM: “Sorry about the wait, yes that can be done, your reimbursement will take 3 weeks”
  • ME: “How come? I had to pay it on the spot. Why do I have to wait 3 weeks for my money back?”
  • VM: “Sorry sir, but that’s how it is. Have a good day!”

So I had to log this here. It’s appalling that as a customer I can get treated this bad. Now I am wondering if I should go with Sky, I heard that they are just as bad. Can anyone share any light on their experiences with Sky and other broadband providers in the UK?

East Africa Undersea fibre optic network is live

Undersea fibre optic network ready to deliver unprecedented capacity and connectivity to Africa

23 July 2009 – SEACOM today announced that its 1,28 Terabytes per second (Tb/s), 17,000 kilometres, submarine fibre optic cable system linking south and east Africa to global networks via India and Europe has been completed and commissioned. Backhauls linking Johannesburg, Nairobi and Kampala with the coastal landing stations have been established and SEACOM is also working with its national partners to commission the final links to Kigali and Addis Ababa shortly.

The launch of SEACOM opens up unprecedented opportunities, at a fraction of the current cost, as government, business leaders and citizens can now use the network as the platform to compete globally, drive economic growth and enhance the quality of life across the continent.

3G Mobille Broadband – Huawei E156G – USB Dongle on Linux


I acquired a 3G Mobille Broadband – Huawei E156G – USB Dongle and really wanted to get it going on my Linux (Ubuntu) laptop. After much looking around and trying several unsuccessfull ways of doing it found a very easy and working solution.

Basically Linux will recognize your Huawei E156G USB Dongle and you can check that by listening to your USB devices, just run the following command on yor terminal  lsusb this should output something like this:

Bus 005 Device 002: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem

Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

if this is working, follow the tutorial on this post 3G Mobile Broadband with Ubuntu-EEE
