Phone & Broadband stop working after moving the router

Phone & Broadband stop working after moving the router - I have been called out for this a few times.

The RJ11 plug (ADSL) will fit into a LAN socket (RJ45) on the router. RJ11 plugs have been designed to fit RJ45 sockets so it will feel right.


This means the ADSL will be disconnected & the LAN socket will loop the line & cause the phone to appear dead.


Make sure the ADSL (RJ11) is in the ADSL socket on the router.

Wifi problems - Apple devices & the BTHomeHub5

Had a customer last week............. with an iMac, very slow wifi, who spent two hours on the phone to BT, only to be advised to reset the BTHomeHub5 - this did not fix it.

There is a fairly common problem affecting Apple products connecting to BTHomeHub4 & BTHomeHub5 routers. This problem results in very slow & unreliable wifi connections.

Devices affected are duel band wifi iPads, iPhones, iMacs & Apple TV.

The BTHub4 & 5 both have duel band (2.4Ghz & 5Ghz) wifi. The SSID ( Network name) is set to exactly the same for each band.

The Apple devices can not deal with this & try to connect to both wifi networks at the same time.

The fix for this is to rename the 5GHz SSID to something different, (I usually add a -5Ghz at end).

The Apple device will then see the two networks as separate & only connect to one of them at a time.

To rename the network you will need to access the router set up via a web browser, type 192.168.1.254 into the address bar & press enter. At the prompt enter the admin password, then click on 'Advanced Settings' and then click on the 'Continue to Advanced Settings button'. Click on the 5GHz Wireless link and click No under 'Sync with 2.4GHz'. Under Wireless SSID edit the name of the network,  I add an -5GHz to the name, so it's clear which network is which. Click OK to apply the settings.

Waiting time, firm appointments


Waiting time for firm appointments is currently about 21 days.

There is currently a waiting time of about 14 days for firm appointments

Firm Appointment waiting time is rising

Waiting time, firm appointments & Urgent repairs

Firm Appointments & Urgent repairs

I only pre-book one firm appointment per day, usually at about 9.30am, This means I have plenty of time to carry out the work required. It also means that most days I have some spare time to attend to Urgent "on the day repairs" in the afternoon. However it should be noted that I do cover a large area & I don't have a team of Telephone Engineers, only me! So I do find it difficult sometimes to attend to non-firm appointments to complete urgent repairs

Firm Appointment waiting time

There is currently a waiting time of about 10 days for firm appointments

Waiting time for firm appointments is on the increase

Waiting time for firm appointments has started to rise, currently about Ten days, Sorry! 

CAT5e or CAT6

I often get asked for CAT6 cable, when I ask the customer why - they say 'because a friend has told them its the best' - I'm not convinced you need a wired network that runs at speeds in excess of 100mbps when  internet download speeds are much slower.

The following is from the Cabling4less.co.uk web site.

  (Q) What is the difference between CAT 6 and CAT 5e cable?

 
(A)Currently there is a great deal of confusion among Ethernet cable buyers concerning whether to purchase Cat5e, or to use Cat6. Most of this confusion comes from a misunderstanding by the buyer that buying Cat6 cable will give them an "all gigabit" network. This is not the case. Unless every single component in the network is gigabit rated, then you will never have a gigabit network, because your network will always run at the speed of your slowest device. Cat5e cable of good quality can run near or at gigabit speeds, it just cannot be "certified" for this use. By comparison, Cat6 is designed especially for gigabit use, and is certified to operate at said speed. It becomes a matter of whether or not you want to pay all that extra money, for little or no noticeable improvement in the performance of you network. In most cases, it makes more sense to go with Cat5e. It is for this reason that most of your new installations in the private sector are going with Cat5e. It is more economical, performs well, and is readily available in many colors. Many IT professionals when asked about why they specified Cat6 for a specific job, often responded stated that they "wanted the best they could get." This is the line of thought behind many purchases of cable. The average consumer often is not aware that there is no real benefit to them to use Cat6, so they let someone talk them in to buying it. Cabling4less.co.uk is committed to helping people make good decisions about cable purchases and we are always standing by to help you.

Report a fault to BT

Report a fault to BT

From a mobile you need to ring 0330 123 4151
From a Land line you need 0800 800 151

BT Invinity- Drops out

If you have BT Infinity (Fibre to the Cabinet) - FTTC & are using the BT HomeHub 5 you may be experiencing frequent internet disconnections. This is due to the VDSL resyncing every few hours.
I have found that using an Openreach fibre Modem is the answer.
Connect the modem to the phone line, then connect from the modem to the WAN socket on the BT HomeHub 5.
The HomeHub still handles the wifi router functions as before but the Openreach modem now deals with the VDSL side of things.

SKY Box causing No Dial Tone

I'm still seeing Sky box problems.... so am posting this again....

Sky boxes that are connected to phone lines can sometimes cause Telephone/ADSL problems.

Phone line appears to be dead -The Sky box may be looping the line. To prove this unplug the Sky box from the phone socket.

Sometimes unplugging the Sky box from the mains power will reset it.

Broadband Slow- It is Very important to have an ADSL filter on the SKY box phone connection. Sometimes it is even necessary to connect two ADSL filters.

REIN & SHINE



Repetitive Electrical Impulse Noise (REIN)

Single Isolated Impulse Noise (SHINE)

This is when electrical items are creating noise,
generating interference in the frequencies used by the ADSL signal.

REIN usually results in a continuous large number of errors, this will give a very poor,slow broadband service. Sometimes it will result in no service at all.

SHINE usually results in a short burst errors, causing the ADSL router to drop its connection.

I have found cases of REIN caused by the following -

  • Faulty TV set, introducing noise into the mains wiring.
  • Noise on mains wiring caused by earthing problem (known as a Ground loop)
  • Switch mode power supply & ADSL cord next to each other
  • ADSL router placed too close to its own power unit
  • Faulty Powerline adapter injecting noise into the router through the ethernet cord. 

Other causes can be -

  • Faulty power adapters.
  • Timers, such as central heating.
  • Christmas tree lights (especially on ‘flash’ setting).
  • PDQ devices.
  • Railway power lines.
  • Street lights.
  • Roadworks temp traffic lights
  • Faulty set-top boxes, televisions and other appliances.
  • Power cables running close to telephone wiring in the home.

Point to Point wireless

Need internet in an outbuilding? I have installed point to point wifi links using Ubiquiti Nanostations - perfect kit -
http://www.ubnt.com/airmax

Wireless - is a two way thing - TX & RX

It is important to remember that wifi is two way.
Transmit (TX) direction -The router sends a signals to the client (laptop, ipad)
Recieve (RX) direction, - The client sends signals to the router.
If you install an expensive wireless router in order to try to increase the range, this will only make any significant difference in the TX direction. You would need to upgrade the clients wifi in order improve the RX  direction.
For this reason it is often a waste of money buying one very expensive router. It is much better to instal an extra wireless access point in a different location as this brings the client closer to the wifi source.

Colour codes-Phone wires

Telephone cables are made up of a number of  "pairs". These are twisted pairs to prevent overhearing/interference.

Blue, Orange, Green, Brown, Slate.

Blue/white, White/Blue is pair one, Orange/White, White/Orange is pair two etc.

In a home wiring situation it is normal convention to use pair one first. In other words the blue wires are normally connected to pin2 & pin5 in a telephone socket.

Just to confuse things a little there is also 4 wire cable that has pair one Blue & Orange, pair two Green & Brown.

And to make things even more confusing BT dropwire & downlead is different again. Pair one is Orange & White, pair two is Green & Black.

Non twisted pair - Telephone cords & some cheap DIY phone wires use different colours again!! No wonder people can get confused!!

Phone & Broadband stop working after moving the router

Phone & Broadband stop working after moving the router - I have been called out for this a few times.

The RJ11 plug (ADSL) will fit into a LAN socket (RJ45) on the router. RJ11 plugs have been designed to fit RJ45 sockets so it will feel right.


This means the ADSL will be disconnected & the LAN socket will loop the line & cause the phone to appear dead.


Make sure the ADSL (RJ11) is in the ADSL socket on the router.

Sky Box problems

Sky boxes that are connected to phone lines can sometimes cause Telephone/ADSL problems.

Phone line appears to be dead -The Sky box may be looping the line. To prove this unplug the Sky box from the phone socket.

Broadband Slow- It is Very important to have an ADSL filter on the SKY box phone connection. Sometimes it is even necessary to connect two ADSL filters.


Alarm wire

Alarm wire is not a suitable alternative to Telephone wire.

For some reason builders sometimes use Alarm wire instead of BT spec phone wire or network cable.

Problem one: Stranded conductors, BT phone sockets have been designed for solid conductors therefore Alarm wires make unreliable connections into BT phone sockets.

Problem two: Not Twisted pair, BT spec wire & Network cable is twisted pair. None twisted pair will pick up noise & cause ADSL problems.

ADSL IP Profile

IP Profile

This is a cap on your maximum download speed.

If your ADSL ISP  uses BT Wholesale exchange equipment then you will have an IP Profile, ( ADSL from LLU  ISPs don't have an IP profile.)

IP Profile - Also known as: BRAS profile

This a speed cap set by the broadband equipment in the local telephone exchange.

The way an IP Profile is calculated depends on the broadband product:

  • 21CN products (Up to 24mbts ADSL2+) the IP profile is 88.2% of the sync rate
  • 20CN products (Up to 8mbts ADSL1) the IP profile is shown in the table below:

Set up an old ADSL router as a Wireless access point

It is fairly easy to set up an old ADSL router (router two) as a Wireless access point. But there are a few possible problems.
Such as -
The PC used for set up needs to be temporally set for a static ip address - Under normal circumstances a PC is expecting to get its ip address from the router but when setting up a wireless access point this is not available. 
Dynamic Host Configuration Protocol (DHCP)

Step by Step guide.

  1. It is important to understand that you are going to extend your LAN ( Local Area Network) 
  2. I shall call the existing router - 'router one' & the additional router - 'router two'.
  3. Set your PC to a static ip address (example - the default ip address of your new router is 192.168.1.1 so you would need to set your PC to an ip in the same range such as - 192.168.1.5 ). (See note above concerning DHCP). If you miss out this step you will loose contact with the router during set up.
  4. Connect a temporary LAN cable from your PC to a LAN socket in router two.

Broadband speed & latency



Speed - To watch on-line TV you need download speeds of at least around 2.5mbts.
Whether you have a superfast 45mbts or an ordinary 2.5mbts connection you will not notice any difference since you will be able to stream video without buffering at both these speeds.


Latency - This is something Gamers will be interested in.
To Play on-line Games you don't need superfast internet with download speeds in excess of 2.5mbts - but you do need low Latency - all the time. Latency is otherwise known as the 'Ping' time.
Short Ping time = Low Latency.


ADSL - can be set up ( by your ISP) for ether fast or interleaving.

Interleaving -
is a form of error correction that enables lines with some interference to obtain faster download speeds, the disadvantage is that interleaving creates longer ping times so is not helpful for gaming.

Fast - less error correction so possibly slower download speeds but shorter ping times.

ADSL & line length

The longer the line, the higher the loss (db)   

All figures are an approx guide & show how the line attenuation affects ADSL sync speed. Also it can be seen that with a long line (attenuation of 50db plus) 24mbit service is often not faster than an 8mbit service. 

It is important to note that download speed will be less than the sync speed.

 

ADLS2+   (24MBit)               ADSL1 (8MBit)

Broadband performance may be affected by any or all of the following

Broadband performance may be affected by any or all of the following

  • The 'line profile' that your ISP has set.

  • The line loss (attenuation) depends on the length of copper wire from your property to the Telephone exchange - this is always higher than the distance 'as the crow flies'.

  • The quality of this wire, with no bad joints, faulty insulation or aluminium conductors. If there is a bad joint the line will be unbalanced & interference will occur. This can often be heard as a very faint 50Hz Hum from the mains power lines.

  • The number and type of other digital services being used by other customers over copper pairs within the same cable. In particular "split pairs" will cause severe overhearing or crosstalk.

  • Electromagnetic interference on the BT line, such as electric motors, electric fences etc.

  • Electromagnetic interference inside your property, such as power units, lighting, central heating, etc.

  • The configuration of the wiring within your property (i.e. the use an ADSL faceplate filter for best performance).

  • The performance of your PC, spyware, software configuration  etc.

Smart TV connection problem

I got called to sort out a Broadband speed issue. When I arrived it became clear that the main problem was that the brand new smart TV was not able to gain access to the internet.

After a fair amount of head scratching, I changed the DNS settings in the router. Replaced the ISP DNS ip address with googles. T
he IP addresses for googles DNS are 8.8.8.8 and 8.8.4.4.

https://developers.google.com/speed/public-dns/
This fixed the problem, Smart TV now working correctly! Happy Customer.

Faults

In all cases when dealing with faults its best to -

  1. Expect the unexpected
  2. Assume nothing
  3. Double check everything 

Faults on telephone wiring often boil down to two basic problems -

  1. A connection that should be present - is not present or is high resistance
  2. A connection that should not be present - is present or is low resistance

Noisy line?

Noisy line?

Hiss? This is most likely a missing or faulty ADSL filter.

Crackle/Static? This is most likely caused by a high resistance connection ( HR Dis) & is very likely to be on the BT network.

High resistance connections (HR Dis) - When you report the fault to your service provider they will carry out a line test, most likely the test result will show "line test OK", This does not mean that the line is actually OK it just means the test did not detect the HR Dis.



In all cases when dealing with faults its best to -

  1. Expect the unexpected
  2. Assume nothing
  3. Double check everything 

Land line faults


To help locate the fault it is always worthwhile making a call to the faulty number & take note of what happens.

If you get -

Busy (engaged) tone - this indicates a short circuit (loop) is likely. Loop faults are usually within the property.

Ring tone, but phone does not ring - this indicates an open circuit. Open circuits are more likely to be on the BT network. 

No tone - This is a probable 'ring trip' caused by a high resistance (HR) loop. HR loops are more likely to be in the property.



In all cases when dealing with faults its best to -
  1. Expect the unexpected
  2. Assume nothing
  3. Double check everything
