Andysworld! to get Superfast Broadband ? Possibly ?

Thursday, May 11th, 2017

If you don’t know, I live in a rural idle in Yorkshire which some have described as a “Shire out of Tolkien” where the hobbits live! (I’m actually a little larger than a hobbit, some would say much larger!)

Lovely as it is, it does suffer one draw back, currently I’m in the 10% of the population without what the Government calls “Superfast Broadband” - at best when the wind blows in the right direction I may get up to 3.5 Meg download speed, my telephone line is still connected to a telegraph pole, and my line length is approx 3.9km from the BT exchange, and that’s not as the crow flies, because the came runs in a junction at the side of the road.

So broadband speed is slow. Three years ago, I blogged when I “nerded or geeked out” - Welcome to Cabinet World! - Andy stalks more cabs! , checking out the local cabs in the area, that had been upgraded, and fibre enabled, and hoped one day that poor old Cabinet Number 10 would be upgraded. All the other cabs in the local town have been upgraded but this sad cabinet has been left, and this is where my telephone line terminates!

3 years later, it remains the same!

BUT…

Whilst out walking in early March 2017, the noisy bugger I am, spotted a notice on a BT Telegraph pole, near my house

Openreach Notice on Telegraph pole

Openreach Notice on Telegraph pole

When I first noticed it, I didn’t read it fully, and thought maybe they were replacing the old telegraph poles because they had rotten, but then I visited When Can I get Fibre ? which I have visited many times, last year!

When Can I get Fibre ?

When Can I get Fibre ?

I could not believe it now states FTTP - Fibre to the Premises, so excited, and I’m sure a little bit of wee came out, I rushed back to the notice on the telegraph pole, and read in more detail…

“to install fibre broadband pole/s” - I’ve read articles, by Openreach, which have suggested they are now using poles and not holes!

Early April, I spotted Openreach Engineers near my Cab 10, but it had not changed, and more recently I’ve been seeing them getting closer to my house.

img_1338I asked this engineer, how far they were going and he said he didn’t know! This was 24 April 2017. Approx 1800 metres from my house.

Today, they are just round the corner! (750 metres away!)  You can see the reel of fibre on the rear of the lorry.

Andy’s gets adventurous with Arduino Prototyping and Embedded Systems and adds a LCD display

Wednesday, May 10th, 2017

So it was naff, hooked up to a computer, so I could read Temperature and Humidity, so my friends at EmbeddedSilicon sent me a LCD readout, I think it’s called a 16×9 something! So now it’s a bit more useful, as a standalone display.

Andy’s first steps into Arduino Prototyping and Embedded Systems

Tuesday, May 9th, 2017

So the problem, I need to measure temperature and humidity, and calculate the condensation risk in my attic!

The Solution

An Arduino and a temperature and humidity module, and I can do the rest, and beam it to the Cloud for plotting!

and I just know the place to go to get this stuff - EmbeddedSilicon.com

and here it is:-

Arduino Uno and DHT11 sensor

and this is the output from the serial console

Console output - sensors readings

Andy get’s adventurous and adds a breakout shield (I think that’s what they call it!)

Got to find a WiFi module, then I can beam results to the cloud…

Three Thingian Gamesody

Monday, April 24th, 2017

For those not in the know, Three Thing Game is a programming Game Jam run over (approximately)
24 hours. Teams of enthusiasts (that’s you people, as well as me and my ‘kind’) gather to challenge
themselves to create a game based on 3 random words that they will be given. At the end of the 24
hours you get to subject your game to a thorough Judging against various criteria like: adherence to
the Things, how complete is your game, and how much money you slip the judge discreetly.

Goodbye Orange @EE, and hello @ThreeUK! #makeitright

Wednesday, April 12th, 2017

Goodbye Orange, and hello Three!

I’ve been with Orange for over 18 years, but times are changing, and I no longer feel it represents good value for money for me, and looking around at the other airtime mobile carriers, I think Three has all the features and more I need now.

  • Unlimited minutes
  • Unlimited texts
  • 30GB a month data allowance
  • WiFi Calling
  • 4G coverage at home, and at work.
  • Feel at Home destinations in 42 countries.
  • 4G Super Voice

and all this costs me less, than what I’ve been topping on Orange for many years!

2017-04-12-101349

2017-04-10-120012

I’m surprised how easily it was to port my old Orange number to Three, Orange just handed out the PAC code, and I entered it into the My3 application, and within 24 hours, it had been transferred to Three.

So if you have my existing mobile number it’s not changed it’s the same!

VMware vSphere Hypervisor ESXi 6.5a on a HP/HPE DL380 G5 - IT WORKS!

Thursday, February 16th, 2017

Sad looking DL380G5

Sad looking DL380G5

Yes, we all know that the HP/HPE DL380 G5 is not on the VMware Hardware Compatibility list, the last ESXi supported operating system was either 4.1 - 5.0, depending upon your Xeon version. But these make ideal lab servers, and one very important function is if you remove the spinning rust disk drives from the disk carriers, you can swap them directly for consumer SSDs. So this makes an ideal test vSAN. 8 SSDs, and if you happen to have enough DL380G5, and we do…. you can build a larger cluster!

VMware HCL

VMware HCL

VMware vSphere ESXi 6.0 does install and run on the DL380 G5, see here - INSTALL ESXI 6.0 ON A DL380 G5 – YES IT WORKS, but for shits and giggles, I want the latest and greatest 6.5!

DL380 G5 running ESXi 6.0

DL380 G5 running ESXi 6.0

and if you try to install ESXi 6.5 on a HP/HPE DL380 G5 with a Xeon 51xx series you will get the following error message

CPU_SUPPORT ERROR

CPU_SUPPORT ERROR

from the VMware vSphere ESXi 6.5 release notes

CPUs removed...

CPUs removed...

You will see the Xeon 51xx series has been removed from the code, and I also believe that more Xeon series will be removed with the next version 7.0 of ESXi, including all 52xx, 53xx and 54xx.

So I just happen to have some Xeon 5430, on my desk as coasters!

Not a matched pair of Xeon 5430

Not a matched pair of Xeon 5430

This pair are not matched…. I don’t think the world is going to come to and end…so, swap them and all will be fine…and the DL380G5 makes this simple, unlock the heat sink bar, unclip the processor clips, remove and replace…

So here you go, ESXi 6.5a on HP/HPE DL380 G5 -” IT WORKS!”

A quick tip, download the last firmware disk from HPE Firmware 10.10, and update your DL 380G5 before you swap the processors! In fact I found this server, had never had any firmware upgrades still on stock firmware!

The muts nuts of Access Points - The Ubiquiti Networks UAP-AC-PRO @ubnt

Friday, January 27th, 2017

Very impressive hardware, with lots of features, and statistics, logging….Good Radios, for 2.4GHz and 5GHz. Setup is straightfoward, and if you know what you are doing for shits and giggles, you can hit the Advanced Button!

The UniFi Controller software can be linked to the Cloud, so you can spy on your installation from remote Web browser or Smartphone application, available for Droid and iThingy.

UniFi Overview

UniFi Overview

An excellent feature shows WiFi devices MAC and IP Address, but also looks up the manufacturer, and also shows device signal quality, and data transmitted and received, I’m now puzzling why my Chromecast and Amazon Firestick are so chatty!

Here are some screenshots from the Droid app

So 16 hours into testing, and I’ve connected a total of 24 devices concurrently, and transferred a massive 23.1GB of traffic across the WiFi network (single access point). All other WiFi devices are turned off now,  no router WiFi or other access points, I’m still using the TP-Link router, at present because my Signal to Noise ratio on the Broadband Line has been reset to 6dB again!

That’s another story…..

Catch you later folk.

Too many WiFi devices and used up all my WiFi beans in my Broadband routers!

Monday, January 16th, 2017

Well the title says it all, with the addition of more WiFi Home Automation devices, it would appear I’ve used up all the WiFi beans in my Broadband Routers, or they easily get overloaded with too many devices. I’ve just added another 12 WiFi devices, and it would appear that’s overkill for a 2Wire 2700HGV and backup BT Home Hub 3 broadband routers.

2Wire 2700HGV & BT Home Hub 3

2Wire 2700HGV & BT Home Hub 3

I’ve been meaning to overall my WiFi for a while, so turned off a dedicated 2.4GHz  and 5GHz access points, and replaced with a single inexpensive broadband dual band 2.4GHz and 5GHz router from TP-LINK Archer D20 AC750 Wireless Dual Band ADSL2+ Modem Router for Phone Line Connections, those devices that have 5GHz have been migrated to the 5GHz WiFi, e.g. Amazon Echo, Nexus, laptops & iPads.

TP-LINK Archer D20 AC750 Wireless Dual Band ADSL2+ Modem Router for Phone Line Connections

It does not look very pretty, and has the standard, LEDs for Power On, 2.4GHz/5.0GHz Enabled, ADSL Connection, Internet Connected and LAN states, this router, is on the top of a shelf, so I need to standard on a stool to check the LED status, it would have been handy, if they were visible… (ignore the whitebox in the above picture, that’s the SamKnows UK Broadband Availability monitoring box)

I’ve now got a few devices from TP-Link, a Chinese company, and the products are of good quality and inexpensive. I’ve got TP-Link  battery  power banks, and recent WiFi smart switches, all with a 3 Year Guarantee, and 24/7 Technical Support! and if you are a real Techie Nerd, you can visit the TP-Link website, and checkout the GUI Management Interface of their products, using their TP-Link emulator

TP-Link router interface

and for shits and giggles, it has SNMP (for a budget router a bargain), you can graph traffic….

So all in all, Good value router, with 3 year guarantee, we will see if it struggles with the WiFi!

Update :- It made no difference, the end result, the WiFi radios in routers cannot cope and struggle with too many WiFi devices, in my case 30, which in the future more and more households, we will start to see the same issue….as more households embrace WiFi, how many WiFi devices are you currently using ?

So I purchased one of these - The WiFi Cure! - Ubiquiti Networks UAP-AC-PRO
