Powerline Adaptor Failure Rate

There have been a few threads now regarding the failure of Powerline Adaptors.
I recently spent £20 for a second hand replacement from the well known auction site, but others seem to be asking or getting BT to replace these, presumably for free even after they are over a year old?
Now we all know these run quite hot, and electronics and heat are not a good match for long life, so if we are going to see more of these fail, can we expect BT to supply a better version or superior make in the future, or replace the current Comtrends if they are proving unreliable?
Its a little worrying that as they run so hot, some of the increasing number of faults might result in a fire?
Mine failed after 1 year and 10 months of use, left on 24/7.
Any thoughts guys...........?

Has anyone out there had success with addition of said Powerline adaptor?
The performance of Ethernet powerline adapters cannot be predicted in advance. One brand might work great in one home, but the same brand and model in another home just won't work.
Your best bet is to make sure that you understand the stores' return policy before you buy, since you cannot know how well.....or IF...any given adapters will work in your home until you try them out in your home.

Powerline adaptor - Hotspot 500 kit compatibility ...

I have a new BT Hotspot 500 kit and am having problems connecting my older Simpler Networks HP200PT64BT passthrough to the new network. The new kit works well but I would like to add another connection to the network by reusing one of my old simpler networks adaptors. I am having no luck. Are these compatible? Am I doing something wrong? Any assistance would be appreciated.
thanks

While all makes and types of powerline adaptors are meant to work together they rarely do. I would also not mix a 200 Mbps adaptor with a 500Mbps adaptor. It will drag your speeds down to the slowest adaptors rate. I would just buy a new 500 adaptor which should work without problem.

Using Time Capsule to create a wifi network from a Powerline Adaptor

OK, before I ask my question, I just have to 'paint the picture'.
I live in a work residential complex, with wifi provided. However this wifi is awfully weak, to the point that I can only sit in one spot to receive it, and then it still drops out. I tried using an airport express to extend the signal, but the wifi router won't allow it.
Through the company that provide the service, I am know using a powerline adaptor ( you know the sort; one ethernet cable from router to adaptor, and another from adaptor in room to laptop) and I get broadband.
I'd like to find some way of getting wifi from that, to my mbp, iphone and appletv all on the same network.
Ok, the crux, I want to buy a Time Capsule, if I do so, by plugging the ethernet cable from powerline into it, will I be able to create a wifi network that 1. Allows devices to connect to it, and 2. Access the Broadband service.
Hope that's clear ;-)

Yes and yes.

WSUS throwing 13002, "Client computers are installing updates with a higher than 25 percent failure rate. This is not normal."

Hello,
Within the past two months our WSUS Server started throwing error 13002, "Client computers are installing updates with a higher than 25 percent failure rate. This is not normal." We currently have 252 computers with errors in WSUS,
and 33 updates with errors. We have never had issues up until two months ago. If you keep rebooting the machine, and keep running updates, they eventually all install. I believe I will see the machines with errors go away as the weekly scheduled
WSUS install runs over and over, and the machines reboot.
- We run IE8 in our environment and sometimes IE9.
- We have 300 clients, all running Windows 7 SP1 x64.
- Our WSUS server is running on Server 2008 R2. The WSUS build number is 3.2.7600.262.
- We created an alternate WSUS 4.0 server on Server 2012, and redownloaded all updates. We put one client on it and it is showing errors on 3 updates, KB890830, KB931125, and KB2917500.
- Clients are throwing errors 800F0902, 80242016, and 80070005.
- I've noticed something with the C:\Windows\SoftwareDistribution\Download folder on the clients. When an update runs and fails, there is a "Install" folder created inside this folder. If you try to open it after the failure you get
"Access Denied" If you reboot the machine, the install folder goes away. (I assume this is a temp folder created to run updates). I've checked the permissions on this folder on various machines and all seems normal. I think
this is the root of the problem, and why we need to keep rebooting to get all of the updates to run.
- I tried deleting the Software Distribution folder on a client after stopping the update service, then restarting the update service. The folder redownloads but the client still throws errors.
- I've gone through our Group Policies looking for anything that can cause this and found nothing. We've created a test OU blocking inheritance, and only applying a WSUS policy in it to make it get the updates internally. I then rebuilt multiple
machines using Dell KACE, and still had failures.
- We run SEP 11 and 12 on our clients. I've tried removing the AV, making sure the firewall was off, etc. It still throws errors.
- I've spoken with our network team, and installed wireshark on a few clients looking for network errors and found nothing.
- I've tried various Dell KACE scripted installs on test machines (erasing and rebuilding the machines from scratch), after which I run Windows Updates from WSUS. They have thrown errors.
- I've rebuilt a machine using Dell KACE, undomained it, then ran updates externally from WSUS going to Microsoft's site, and I'm still getting errors.
- I've tried removing all software from the Dell KACE build to where it is just installing the OS and I'm still getting errors.
- I tried taking a plain Windows 7 x64 DVD and installing that on a test machine, then without domaining it and without installing any other software, running updates from Microsofts update site. This seems to work, althrough it does throw some errors
but I believe those are related to having to reboot your machine in order to complete the updates (I can't remember that error code at the moment).
Has anyone else been experiencing this? Any suggestions as to how I can fix this?

Hi,
Error 800f0902
Please try the method in this thread:
Error
Code: 800f0902
Error 80242016
If you receive Windows Update error 80242016 while checking for updates, it might be caused by a connection interruption between your computer and the Windows Update servers.
80070005
Usually means access denied
Since it worked perfectly for a while, did you make any change on the server? Any applications new installed on clients?

Anyone else seeing high failure rates with Meraki MR16?

I'm at a small college, with about 110 APs across about 20 buildings. We'd filled up our aging WCS/WLC 4400 wifi system, and so in January replaced it with Cisco/Meraki. We ordered our equipment in late December, and installed during our Winter break. Thus, our first new APs came live about Jan 10th. We started by expanding our wifi coverage into four dorms, and then swapped out the 75 Cisco APs from our old system.
I had two MR16s fail withn the first couple weeks. Got an email report that they were offline, and on investigation found that they had only the Power LED lit orange. No response at all to the reset button, and no sign that they are attempting to boot (No console port on the MR16, but it doesn't seem to boot enough to give any error signal via the LEDs.)
Since then I've had four more failures, for a total of six out of 105 APs deployed. (I still have a few in boxes to go spots where I need to pull cable first). None of these were DOA, they all came up just fine, and failed after a week or a few weeks of operation.
I'm assuming that we just got a bad production run or something, but have no idea how wide scale an issue it might be. So, please let me know if you've seen a failure rate above, say, 1% on Meraki APs.
Conversly , if you got a bunch of MR16s in December 2013 or Jan 2014, and they are all working just fine, let me know that, also.
Thanks,
Steve Bohrer

I got an email from a tech who had been involved on my latest ticket about an AP failure:
"I've scheduled the software upgrade for your next maintenance window on Wed 11th June at 6am. Alongside the fix for the issue contributing to MR16 failures the following enhancements are included:
New VLAN debugging tools to help detect VLAN configuration problems
Distributed layer 3 roaming (no concentrator appliance required)
802.11k (radio resource management) and 802.11r (fast BSS transition) wireless protocols
Hotspot 2.0/802.11u wireless protocols
Enhanced stability and performance improvements"
He also suggested that I could push it out sooner by logging into dashboard.meraki.com and then going to the Configure > Network-wide settings page. On that page, in the "Firmware upgrades" section was the date the tech mentioned, but also the options to "Reschedule the upgrade" and to "Perform the upgrade now". I scheduled it for early the next Saturday morning.
(These options are usually greyed-out if your firmware is up-to-date. The page also notes when you last did an upgrade; however, I don't know if there's anything that shows the firmware version you are running.)
I asked the tech who sent the above for more details about "the fix for the issue contributing to MR16 failures" but he says it is not public information.

Time Capsule and Powerline Adaptors - Internet periodically freezing

Hi all,
I hope you can help with a problem I am having with my home network. The Virgin Media broadband in my home arrives in my home office and, in the past, when I connect my Time Capsule to the VM router and use it to generate a wireless network I get a very poor wifi signal in the rest of the house - the office is at one end of the property and I suspect there are several metal beams in the wall blocking the signal.
So, to improve the network I bought some TP-Link Powerline adaptors. I have run an ethernet cable from the VM router to one adaptor, put the second adaptor in the living room and attached an ethernet cable from the adaptor to the Time Capsule. The wifi signal from the Time Capsule is now excellent in all parts of the house, but, for some reason, the internet periodically "freezes" on any wifi or wired device that I attach to the TC. There is no issue with the wifi reception - all the devices continue to be attached to the TC with great reception. The broadband service is also not at fault - I have an iMac connected directly to the VM router in the office and the internet continues to run perfectly on that computer during these outages. Each outage lasts 1-2 minutes, occurs about every 5 minutes and during that time I am not able to do anything on the internet - it is not related to a particular site
Does anyone have any suggestions as to what is going on?

Powerline adapters are not ethernet cables.. they have their own issues.
Test the setup by plugging a laptop/nearby computer into the powerline adapter and see if you have issues at all. Load it up since the TC is going to run it fairly hard with multiple computers connected.. ie Run a few downloads and do browsing etc at the same time.. check the actual speed of the link and how stable it is.
If it is fine, then the issue is the TC.
Alternatively just get another router, eg TP-Link WDR3600 which is only about $70-80. Borrow one from a friend. If that has no problems then you can pretty well say the issue is TC.
In that case we need to know exactly which TC running exactly which firmware. This issue is well known in the later AC model.. it is caused by some issue with the WAN port not holding the line correctly. You may need to do a bit of work on it and sadly apple have removed logging and lots of abilities from the TC so it is now pretty hard to do any realistic testing. Hence if the new router works.. keep it and set the TC as a Wireless AP.

Faulty Powerline Adaptor - no response from techni...

Hello,
One of my Comtrend Powerline Adaptors gave up the ghost on Monday 8th March, not showing any lights at all. When I unplugged it, I found that the two plastic mounting pins had basically disintegrated and the whole front of the unit came off in my hands.
After consulting the troubleshooting guide, I only got a very dim power light and the unit wouldn't reset. I followed the advice given and reported the problem to the BT Vision Technical Help Desk via their online form.
I received an automated reply but have had nothing else in reply since Monday. What's the usual response time for the technical help desk? Is is worth pursuing my original report or is it likely to be lost in the system somewhere!?
Any help from the moderators would be gratefully appreciated
Cheers,
Clare

Powerline adaptor/ plug recommendations please.

Hi everyone.
Please can you recommend some good powerline adaptors please.
At the moment I only have the old netgear's 85mbps plugs, these only allow me to pull through 17 Meg.
When directly wired I manage to get the full 37 Meg download.
My wife will not allow me to have cable trailing around the house so better plugs are the way forward.
Are these ok, will they do the job.

Many thanks..
Solved!
Go to Solution.

Many thank's.
Pc world only had a limited range in the one that was close to me.
I ended up buying the Devolo 200AV Wireless N starter kit.
The good speeds are back..

Powerline Adaptor Question / Volume button

hi there, got BT Vision a few days ago. You know the plug socket that is on the powerline adaptor whats that for? Can i plug anythig in that like a plug? as its quite wide you cant plug in next to it so perhaps thats what its for?
also my controller works fine, every button, but volume up makes it go to a weird teletext thing and volume down switches it to analogue TV which is a bit weird. any ideas?

You can use the plug socket on the power line for anything. Its there to replace the one you have used to power the device.
Regarding the volume buttons, it sounds like the remote is programmed incorrectly for your television and use need to enter the correct code for the remote so that it send the right signals to the televison for volume up/down. The list of the codes, and how to programme the remote, are in teh vision instruction manual - alternatively post back, on this forum, with teh make and model and someone might be able to supply teh correct code.

BT VIsion Powerline Adaptor

I've been sent a new BT VIsion Powerline Adaptor, but no information on what I'm to do with it or why I've been sent it... Can anyone send me in the direction of why and what I should do next?

There is a small potential danger with the old ones. Follow the instructions to set the new ones up, replace the old ones and send them back in the bag provided.

Powerline adaptor issue

Hi,
We want to move our BT Vision box from the kitchen to the lounge.
In the kitchen it works on a powerline adaptor as it is too far from the hub to hardwire.
When we transfer it to the lounge, the powerline adaptor looks like it is working fine - all the same lights as when connected in the kitchen - but we get the message ' Not Online' on the TV, and cannot pick up our Vision service.
If we move it back to the kitchen again, it works fine.
We have plugged an extension into the kitchen and run it through to the lounge, plugged the poweline in so it is effectively working on the kitchen electricity circuit and it again works fine.
We have one consumer unit, nothing complicated, and cannot understand why the lounge will not work!!
Can anyone help??
Thanks

There are many threads on this forum about the use of Powerline adapters. If you are lucky they will work, but there is no guarantee that they will. The best chance of them working is if they are on the same ring main, but even then they can cause problems. Bt does not now approve their use.

Home Hub 3 Losing Powerline Adaptor Connection

Hello All,
First off, apologies if this question has been posted and/or answered elsewhere but I couldn't find any posts that duplicate my situation.
I have BT Infinity with a Home Hub 3 (installed in July last year) and all seems to be well except for the ability of the Home Hub to keep ethernet connections alive.
My setup;
1x HH3 in the study, connected to the Internet as per usual & performing DHCP duties with a gigabit switch to connect all the 'local' hardware.
1x Comtrend 9020 Powerline adaptor pair to connect the apple TV in the lounge.
The problem;
The powerline adaptors - which I only chose after seeing that they were the same kind installed by BT Vision engineers, so they must be considered compatible with the HH3, right? - seem to keep 'dropping off' my network. Originally, I had them using DHCP addresses because I figured that the BT Vision customers wouldn't be doing any additional configuration but that didn't work so I guessed that there must be something that the BT Vision box does to keep the connection alive.
Now I have tried switching to fixed IP addresses but that also seems to be a dead end because they still drop off the connected devices list on the HH3.
It would appear to be the connection between the HH3 and the Powerline adaptors which is being dropped because when this happens I am unable to login to the powerline config interface (browser based) and pings are not responded to.
If I want to stream content to the Apple TV I now have to resort to resetting the HH3, the powerline adaptors and the Apple TV, which kind of defeats the convenience factor a little (plus it would be far too technical to explain to my wife). BTW - the full reset process was arrived at after trying different combinations of resetting the 3 components in the chain with no success.
Any ideas?

You must use fixed IP addresses outside of the home hubs DHCP range, otherwise you will have the same problem
See Static IP
I think you can do that for the Powerline adapters as well.
Login to the Powerline web interface, password is BT, I think there is a setting to use a static address. You will need to use a different address for the other Powerline adapter.
There are some useful help pages here, for BT Broadband customers only, on my personal website.

BT Ethernet Powerline Adaptor Issue

I have had a BT Home Hub 5 setup in my hallway for over a year now and I used to connect my computer and laptop to the internet via three Netgear powerline adaptoss which worked okay. I love online gaming so reliable high speed internet connection is essential. But, problems kept arising so I decided to replace the Netgear powerline adaptors with BTs broadband extender 500 kit.
Currently, I have one adaptor connected directly to my router, and two more upstairs in different rooms. I managed to setup the kit after some time due to a really unclear instruction manual and got the three lights on all of the adaptors green. However, the ethernet green light is continuously blinking...
The first day I experienced okay connection speeds, but today was the complete opposite! This happened throughout the day and I finally decided to try again later during an off-peak time at 11pm. Same result.
Firstly, the data light on the adaptor connected directly to the router sometimes goes orange, I understand this means medium transfer speed, but this didn't happen at all yesterday. Next, the adaptor in another room upstairs had an orange data light and sometimes all the lights switched off then back on again as if the adaptor was reseating itself?! My laptop connected to this adaptor could not connect to the internet at times and when I tried to view a simple Youatube video, it buffered and lagged! This has never happened before. Also, in the same room, when I tried to access the internet via the Wi-Fi with my tablet and laptop, the same issue arised - very slow internet. Let me remind you that I have not experienced this slow internet speed before.
Meanwhile, someone was watching Netflix in another room upstairs using the third BT ethernet adaptor. They said the streaming was buffer-free and perfectly fine.
I am very confused as to why the internet connection with was fine for someone else in my house using the broadband extender, but not for me. Could it be because I am using three BT broadband extender adaptors instead of the two? But when I used the Netgear adaptors, I used three as well and there were not as many issues than I am facing now...
Any help would be greatly appreciated. Thank you for reading.
p.s. All the BT powerline adaptors are coronary enacted directly to the lead rival rockets and I know for a fact that there are no problems with my devices that I use to try and access the internet.

Powerline adaptors are tricky things, as they rely on your mains wiring to carry the signal. All sorts of things can affect the signal strength, and consequently the speed.
Interference from nearby appliances can affect the signal. If possible, try another socket in the room.
As a general rule, sockets on the same ring are best. The adaptors should work on different rings off the same consumer unit (mine do), but at a lower speed.
If you have a complicated wiring system with multiple distribution boards, then that may affect the speed a lot. If you have a three-phase mains supply, then they are unlikely to work on different phases.

31 percent failure rate for G5s with 20-inch screens

The September issue of Popular Mechanics says Apple surveyed iMac G5 owners on the heat problem and found an 18 percent failure rate among the original iMac G5s with 17-inch screens and a 31 percent failure rate for G5s with 20-inch screens.
Not even one year old, soon I expect these numbers will rise higher since so many people have the white band on the bottom of the screen and have not reported it yet. Hundreds of post in the display section on it....
