Random disconnects on Infinity using an HH3 type r...

My apologies in advance if this topic has been covered before, but a search of the forums didn't come up with anything that matched.
Is anyone seeing odd problems with HH3 Type A router disconnects/hangs?
When I got Infinity last year, BT supplied a HH3 type B unit, and I was affected by the 'slowing to a crawl' issue that's been covered in the forums here in the past. After it happened so many times I contacted BT and they replaced the HH3 type B with an HH3 type A, which cured the slowing issue. All has been fine until about ~6 weeks ago, and now I'm seeing a problem on the type A router.
Typically, I start to notice lengthy DNS resolution issues, then the blue broadband light turns orange on the HH3, and I loose Internet access. If I connect to the HH3 with a web browser I see a 'Connecting' message next to a spinning blue circle. Any attempt to disconnect and reconnect via the browser does nothing (as in the web browser session hangs), so I have to power cycle the HH3, and when it's re-booted everything is back to normal. I haven't touched the white OpenReach at all since I installed the HH3 type A. Whenever I get one of these hangs the OpenReach box lights look normal.
This HH3 behaviour seems different to the odd short disconnect and automatic re-connect that I've seen once or twice during the last 11 or so months, because once one of these hangs happens the HH3 never seems to reconnect on its own. During any outage my phone line seems fine, although of course that's no guarantee that everything's OK.
I do have a USB flash drive plugged into the HH3, but whenever one of these router hangs occurs it wasn't being accessed, so I don't think that that's relevant. From what I can tell the HH3 has the latest firmware: 4.7.5.1.83.8.57.1.3. My throughput seems about right for an Infinity1 connection (36 down, 8 up), so I have no real idea what this might be. Like many customers, I'm loathe to contact BT Broadband Support unless I really have to.
So, with the above in mind, could the collective (ah, Borg) offer me some advice please?
-- Is it an HH3 issue?
-- Is it worth replacing the HH3 with something else? A couple of my colleagues run their Infinity connections that way. I wouldn't want to spend the earth on a replacement router, but if that is an idea, what should I go for? How easy are third party devices to set-up with Infinity?
-- Is it a line issue? TBH, I don't think so. Every time that it's happened thus far power-cycling the HH3 has fixed things.
Don't get me wrong -- it's not a big problem generally, but if you're in the middle of a big download, streaming stuff to watch on TV or end-up with your wife bending your ear because things don't work, then it does get to be a bit of an issue.
Any advice or suggestions would be most gratefully received and appreciated.
Cheers
Clem

Hihi,
I would completely reset the HH, then re-enter details and see if the issue still arises. Since you haven't touched your white modem maybe turnign it off and on could help (then never touch it again :-) ).
If it happens again after that it might be worth a call to support as they can tell you if they can see any issues on your line. Then you will have more weight when you ask for a new HH when they say its fine :-)
If the HH meets your needs then try for a replacement. There was a number in the HH box for replacements. You might be annoyed if you bought a new router only for it too have the same issues :-/ So a pain yes, but for the greater good.
Good luck,

Random disconnections

Since the beginning of December I have been getting what seem to be random disconnections with my broadband. Pages won't load for 30 seconds or so then it all goes back to normal.
Some times it will happen only a couple of times a day and other times (like tonight) it is every ten minutes. I have a HH3 and modem and all the lights stay on as they should be, just pages wont load, at the bottom of my browser sometimes I get the message "cannot resolve host"
I got on to @btcare via twitter and they have been brilliant, sent me a new HH3 and arranged for an engineer visit who found a line fault, fixed it but half an hour after he went, the disconnections started again.
It affects my PC (wired) 2 laptops and mobile phones (wireless) and also my Youview box (the internet channels will freeze, then come back about 20 seconds later)
I have fitted a new cable from the modem to the phone socket to no avail.
@btcare are phoning me back Saturday to see if the disconnections have stopped.
Most of the time it is just a small irritation and can be lived with, but times like tonight it is a royal pain in the bum!
does anyone here have any ideas as to what could be causing this problem?

Ive been getting random disconnections since infinity was installed. Wife complains, kids complain. Ofcourse since it doesn't usually last long by the time I phone customer services (who are useless) they think there is no problem. Cant wait until my contract is up and I can get back to a proper broadband supplier. No signal even when all three lights are blue on the router.
I would strongly advise anyone contemplating getting bt infinity to reconsider. Worst broadband I have ever had. Great when it works just doesn't work for long enough periods without dropouts. At least 10-20 a day.
What if anything have you tried to remedy this? Are you connecting by wireless or by Ethernet. Do you want suggestions of what to try or are you just wanting to pass on your experience?

BT infinity 2 Random Disconnects

Hi I have had BT infinity 2 for almost 3 weeks now but I have been disconnecting from install till today.
The disconnects are random and I can disconnect 3 times a day or its stable for 4 days straight before disconnecting.
My speed however stays close to the engineers estimate of 70/20 ( currently connected at 67/20) which is great.
I would like to have a stable connection but don't know if its my line to the cabinet of around 300metres or my equipment.
I'm currently using the Draytek 2750n and can see that im getting CRC errors.
I have used the HH3 and O/R modem and have had disconnects.
I connect wireless on my pc and get speeds of 40/8 which is fine since its a limitation of the wifi card.
Have tested via ethernet and get 65/12 but still get disconnects.
Any help will be greatly appreciated
Thanks

can you enter your phone number and post results remember to delete number https://www.btwholesale.com/includes/adsl/main.html
if you have a hh5 can you go to troubleshooting then helpdesk and post 1-12
can you rumn btspeedtester and when first test completes then run diagnostic test and post results

Sporadic random disconnects this week, very bad to...

I've never had any problems with BT Home 2.0 until this week, I have moved nothing about in my room nor adjusted any settings on the hub and my PC. I have changed the filter and still the same problems occur. I've noticed a lot CRC /HEC errors on the up stream... I live in Bristol if that might help to solve the problem. Maybe something next door could be affecting the line or a BT engineer has messed around with something on the exchange? (I am using a wired connection BTW). Any help and suggestions appreciated, thanks, Rob.

Sorry I can't offer any magic suggestions.   I had been getting regular disconnects for some months and even though I was keeping the router continuoulsy powered to avoid loss of line synchronisation it still was occurring.   See my comments in the thread "Re: Disconnects on Accessing HH and Random Disconnects at Night" for 10 Feb.
The Forum Moderators were very helpful and responded to my queries and arranged four visits from OpenReach to try and sort out the problem.    Eventually they decided that there was a fault in the exchange boards and made some change. Subsequently I kept the router powered up until the 13 May to make sure there was no synchronisation interrupts.   The line eventually stabilised at 14,336 kbps.   It has remained at that even with my logical disconnects at night from the HH Home Page.
I found from a search back in Jan as reported in the thread "Re: HH Type B Energy Consumption & Switching Off the Router" , that the Type A software version was 8.1.H.J. I don't know if it has been upgraded since.   I have found for my Type B that when received it back in Oct 2010 the ver was 4.7.5.1.83.3.5. and it is now ....83.3.18.   - when it was changed/upgraded I don't know.
As I say, although I still get random disconnects, it doesn't seem to affect my line rate.   Not sure if it is noise on the line (i have made a quiet line check and that is OK) as the Noise Margin is ca 7.6-9.1dB. I get disconnects sometimes when I try to look at the ADSL Settings, etc., having typed in the password for access. I have just looked at my Events Log and there have been a number of disconnects today since the router was logically connected at 14:04 this afternoon; 5 in total I think!   And the rate is still shown as 14,336 kbps.

Having said that your rate is quite reasonable and unless you are playing games or watching videos perhaps the interrupts will not be serious.   We only use it for email, family history, ebay and browsing so it is not really noticeable.

WAP321 random disconnecting clients

Hi all,
I'm having problems with my WAP321 that is randomly disconnecting clients. It's not disconnecting all clients, but just a couple of clients. It's random which clients get disconnected and it can be different clients that will be disconnected when it happens a couple times, but they do get disconnected at the same time.
My setup:
Cisco ASA5505
|
Cisco WAP321
|
Cisco 7925 phone - iPhone - Macbook - three IP cam's (different brands) - and some more clients
Last time it occurred I just for sure changed DHCP server from Cisco ASA5505 to two windows servers, now it happened again, my 7925 started beeping (enabled SSID monitoring on it so it alerts when it isn't connected to my Callmanager) and my iPhone couldn't connect to the SSID. My Macbook was still just connected. Retrieved a diagnostics report and checked the logging, rebooted the WAP321 and everything started connecting again.
Noticed screens are scaled so hope it's readable...
The MAC address is my iphone. I turned off the 7925 because the beeping was annoying so no logging from the 7925 trying to connect.
Logging is saying:
assoc request from [mac] BSSID [bssid] SSID LEVELS
STA [mac] deauthed from BSSID [bssid] reason 3: STA is leaving IBSS or ESS
There is nothing wrong with the coverage, the WAP321 is about ten feet from the iPhone and Cisco 7925 phone
Can anybody help me how to best troubleshoot this issue. I'm not familiar with the troubleshoot/debug options available for the WAP321

Dear Wesley,
Thank you for reaching the Small Business Support Community.
There is an opened caveat on the latest firmware release, version 1.0.4.2; CSCue24521:
-Symptom: Some clients may lose wireless connection when authenticating via Captive portal.
-Workaround: Reconnect wireless devices.
If this is not the case I'd like to know if you have tried using a different IEEE 802.11 standard, same as a different authentication type. If you are not running the latest firmware release I then suggest you to, and something else I've seen from experience that fixes similar issues is to reset to factory conditions and reconfigure manually.
http://software.cisco.com/download/release.html?mdfid=284152656&softwareid=282463166&release=1.0.1.10
I hope you find this information helpful and please do not hesitate to reach me back of there is any further assistance I may help you with.
Kind regards,

Disconnects on Accessing HH and Random Disconnects...

System is BT HH Ver 2.0 Type B with Firefox v.3.6.13
On a number of occasions I have found random disconnects in the event log and disconnects when I go to access the HH and type in my password, when the BB light goes out and then the yellow comes on and it begins the reconnect sequence.   These are shown in the Log, but it doesn't seem to make any obvious change to the line synch rate.

The events at 20:02 and 22:55 were caused by my accessing the HH and typing in my password.   The others were random disconnects - the HH has not been switched off for some days and the computer was only switched on aorund 15:00 hrs.
The line synch rate at 23:12 is
Downstream   10,134 Kbps
Upstream   1,078 Kbps
The changes to the Noise Margin/Attneuation and Power are very minor fractions of a dB from previous checks. The line is quiet. Distance to the Crowthorne exchnage is ca 966m.
I have even had disconnects using IE 6.0 on Feb 3.
Does anybody else get these effects?   Is it a faulty HH?   Is it some interference on the line?
This looks similar to the problem under "home hub keeps resetting" from "technobaz" today

Further to the saga of disconnects shown by my HH2 Events Log I have had helpful support from Forum
Moderators.   They arranged for OpenReach technician to call again subsequent to the 25 Feb visit on 9
March.    The Moderators could still see my line problems from their site (where ever that is!).   I have had
the HH2 Type B powered on for over two months (to ensure line stability) and the line Down Rate has
gradually reduced
17 Jan 2011    Downstream   11,347 Kbps     Upstream   828 Kbps
       Noise margin (Down/Up)   14.8 dB / 12.6 dB
       Line attenuation (Down/Up)   27.0 dB / 11.9 dB
9 Mar 2011   Downstream   1,151 Kbps    Upstream   1,078 Kbps
        Noise margin (Down/Up)   27.9 dB / 8.0 dB
       Line attenuation (Down/Up)   26.7 dB / 11.8 dB
the ADSL statistics had varied slightly over the period and the Event Log typically showed disconnects with
the text, e.g.
Feb 2 06:13:45 2011   (112240.430000) danube_dsl_ioctl:73: Failed ioctl 270 errno 22

Feb 1 22:42:42 2011   (85267.560000) danube_dsl_ioctl:73: Failed ioctl 250 errno 22
My line still showed the disconnects.    I also tried my neighbour's HH2 Type A for 24 hrs on 7/8 Mar for
comparison. He was getting no disconnects on his line.   The Type A Event Log showed on the 8 Mar my
line disconnects, albeit in a slightly different set of "text language" to the Type B - so it was not a router
problem!

On the 9 Mar visit, OpenReach made a series of comprehensive tests isolating the house/manhole line,
checking equipment in the exchange and green street interface box/exchange line.   My house line (some
10m) was showing good insulation resistance and similarly the box/exchange line a very high insulation
resistance.   The value surprised me, but a Google check shows a value of 10000 Mohms/km may be
typical.
However, somewhere between the green box and my pavement manhole the insulation resistance was low.
I am now awaiting for the bad section to be located and my present twisted pair to exchanged for a good
pair.   I hope after a few days the Line Synch Rate may get back to the original values.

My phone will randomly disconnect from the wifi and when I retype the password it says it is wrong. It will eventually work but I have to wait for a message to pop up on my screen to allow me to retype the wifi password.

When I first got my phone it worked perfectly fine with the wifi. Although later on I began to have problems connecting it. It will randomly disconnect from the wifi and when I try to retype the password it tells me it is wrong, although it is right. It will eventually work but in its own time, a message will pop up and allow me to type in the password and it will work. But sometimes it takes an hour or more and sometime it takes 10 minutes. I've seen where other people have had this problem but I don't know how to fix it. I'm not sure if it's an issue with my phone or if it's with my wifi. Does anyone know how to fix this?

Does this happen with all Wi-Fi hotspots? A specific one?
Have you tried forgetting the Wi-Fi connection and then reconnecting to it?
What about power cycling the Wi-Fi router?

Undocumented 'random disconnection' from manually connected wireless

This is all the information from when I fist see an wireless interface.
All, I can tell is that my wlp5s0u1 doesn't go down, but a few seconds before I plug in my wireless bridge, or enp4s0, my 'Internet stops...' Or I can't search google, and my youtube stops streaming, conky says that about 30bytes get transfered from that point on, and there is no errors?!
I'm not on a laptop, and my device's power saver is set to off. And as I'm not getting the second error I don't know how to fix this.
$ iw dev wlp5s0u1 get power_save
Power save: off
(Sorry if this is blatantly obvious, I've only had arch for under a month, with no prior Linux experience, and my dad can't help me with it too!)
EDIT:
Please can someone please tell me something that I can try or look into to resolve this, I have a useless dongle now, and an Internet connection that drops at least 50% of the packets.

Random Disconnection From My Wireless Access Point

I got my MacBook a few weeks ago, wand I'm loving it... for the most part.
Info: I've been using my Linksys WRT54G router for years. I've never had a problem. I currently have a desktop Mac connected to it along with my MacBook, and the connection on the Mac is fine.
*The problem:* My MacBook doesn't hold a steady connection to my router, even when I'm just mere feet away.
*What happens:* I have a very strong connection on my WiFi with the built-in AirPort. Then, a few seconds later, all of the 4 bars drop to 0 for a few seconds, jump back to 4, go back down to 0... you get the picture. I find this frustrating, as the internet may shut down for a minute at a time, regain connection for a few seconds, and then lose connection after about 10 seconds. I am unable to use iChat (it shuts down whenever I lose connection), or easily browse the internet.
*I know it's not the router. My desktop Mac connects with ease. Should I take my MacBook to a Genius Bar?*

Network drives randomly disconnecting, unable to reconnect

I have been having an issue with network drives randomly disconnecting. When I try and reconnect using the Connect to Server dialog, the share is greyed out. My current workaround has been to open up terminal and run umount /Volume/Share_Name, and I am able to connect again afterwards. This is happening multiple times a day, and across multiple servers. I have poked around the forums and seen some people with similar issues, but the solution of connecting with cifs:// instead of smb:// has not made any difference.

which ultimately means apple didn't do enough testing before releasing the last patch
This is not always, and may not be, the case. What many don't realise is that many 3rd party developers stray from the 802.11 series specifications in an attampt to boost speed and get one up on their competitors. For instance D-Link, amongst others, use a short preamble setting by default in some of their routers to improve performance. However, this is non-standard and when it comes across wireless network adapters that don't support this then you have problems. They assume that their network adapters are being used for "maximum speed and compatibility". Whether Apple should or should not support a short preamble is another subject altogether.
However, I do agree with you in that Apple should put more work into their Airport software.

CUCM Random disconnect errors

I have a client who is getting random disconnect errors from his cucm servers. They seem to encompass other network errors at times as well, but not always. I'm having a hard time telling if its cucm or if it is a network issue in general.
I pulled his core logs and at the time of disconnect messages from RTMT I'm seeing this:

and lots of them, for a few minutes and then it stops. When I search around for solutions for this I see "contact TAC" repeatedly. Can anyone help me determine if I have a cm problem or a network problem. He did reboot the cluster 12 days ago and it didn't stop the problems. The disconnect errors related to all components of the phone system (cucm, cuc, uccx, cups) and have been anything from "SDL link to remote application is out of service", "OUT-OF-SERVICE AppID : Cisco UP Presence Engine ClusterID", "
The Cisco UP Presence Engine service on the peer node of a subcluster has failed AppID : Cisco Syslog Agent ClusterID", "user 2 ntpRunningStatus.sh: Primary node NTP server, SVUCCX01, is currently inaccessible or down"
So its just like all communication breaks and then comes back again. I'd like to do as much leanring as possilble with this and not just run to TAC. Any suggestions?

Hi Dustin,
Please see the explaination for the error you are getting:-
CCM_CALLMANAGER-CALLMANAGER-1-SDLLinkOOS : SDL link to remote application is out of service Remote Application IP Address [String] Unique Link ID [String] Local Node ID [UInt] Local Application ID [Enum]Remote Node ID [UInt] Remote Application ID [Enum]
Explanation   This alarm indicates that the local Unified CM has lost communication with the remote Unified CM. This alarm usually indicates that a node has gone out of service (whether intentionally for maintenance or to install a new load for example; or unintentionally due to a service failure or connectivity failure).
Recommended Action   In the Cisco Unified Reporting tool, run a CM Cluster Overview report and check to see if all servers can communicate with the Publisher. Also check for any alarms that might have indicated a CallManager failure and take appropriate action for the indicated failure. If the node was taken out of service intentionally, bring the node back into service.
Reason Code - Enum Definitions
Enum Definitions - LocalApplicationID
Value
Definition
100
CallManager
Enum Definitions - RemoteApplicationID
Value
Definition
100
CallManager
The most common Lost communication for CallManagers could be Callmanager server hang, network problems or high CPU
You can use RTMT to monitor this.
CM servers keep a TCP connection to other servers in the cluster. When that TCP connection is broken due to network connectivity or lack of server resources, the above error is generated.
Also the sdi traces you have provided won't be useful to analyze the problem but rather please take detailed sdl traces.
If possible then take SDL detailed traces with sniffer filtering TCP port 8002 in order to find out if this is a Network problem or not.
Sometimes due to highly fragmented disk can cause heavy disk I/O utilizing all the CPU.
Was there any upgradation or migration activity was carried out in network?
Please check the server NIC and switch NIC or other NIC have the same speed/duplex settings.
Regards,
Nishant Savalia

Moving BT Infinity modem and HH3 router to another...

Typically my master socket is in the dining room and all my IT kit is two floors up. Was using HH3 as Total Broadband in my loft with ethernet connection out to my Apple Airport Extreme which ran the network - everything hunky dory but I wanted faster speed - hence Inifinty.
BT Engineer had a look at my set up, started talking of bringing in a hoist into my back garden to install new Master Socket and it just seemed easier to install in the dining room and use the HH3 as router and re-configure my network - wrong! Most devices lose contact with the HH3 on a regular basis, therefore I want to re-look at installing Infinity into the loft and revert the HH3 to a ethernet connection out to my Airport Extreme. I understand all the engineers do at the master socket is install an Infinity faceplate. I've tried replacing the loft extension with a split front BT master socket and moveed the Infinity faceplate - result; voice remains but no DSL on the white Open Reach modem.
Are there any suggestions what I need to do? The original extension had four wires connections (white & blue, blue, orange & white, white & orange) but the BT master socket only has three positions and my original master socket only has two wires connected.
Thanks, Andy

Hi Andy and welcome
In THIS POST Phil recently wrote.-
"Very proud of myself this afternoon. I'm not much of an expert when it comes to DIY but I have managed to hardwire the router from the back of my house to the office on the first floor at the front. After much contemplation, I decided to buy some external cat5e cable and run this along the same points as the SKY feed. The result looks pretty good and I can now get 37.5Mbps upstairs as well as down. Result."

Wrt600n / wpc600n random disconnect issues

hi,
i've been running the new AP / cards for a few weeks now, and am seeing some weird behavior on them.
when connected to the AP using either vista (using windows to manage wireless setting), or in xp (using the linksys utility), i'm getting random disconnects. the wireless connection will just drop from 1-10 seconds, then reconnect on it's own.
for these connections, i am forcing the AP and cards to use the n band.
the AP is set to N mode only, and all other settings on the AP are set to Auto. the clients are using all default settings as well, and this issues occurs during web surfing, email, etc. and is repeatable.
any suggestions?

if ur using it on vista
please download the drivers for vista from

ESATA HDD Random Disconnect SOLVED!!!

Fellow ThinkPad owners:
I've spent the greater part of the past two days trying to resolve the issue of my eSATA connected ThinkPad 500GB SHDD's tendency to randomly disconnect itself. I had just gotten my new W520 with Windows 7 64bit preinstalled, and was happily working away (I'm a banking applications developer) when out of the blue I would get a ThinkVantage message asking me to recover my current files to the C:\ drive. To my surprise and dismay, I noticed that this was occurring immediately after my HDD had "dropped" off MyComputer's list of available drives! I spent all day on the phone with Lenovo tech support to no avail. I did notice, however, that opening the ThinkVantage ToolBox (PC Doctor application) was a surefire way to cause the HDD to "drop" off immediately.
SOLUTION:
Uninstall ThinkVantage Toolbox!
The problem has now ceased, and I've also noticed that the fan in the W520 is not nearly as overactive as it had been while the ToolBox was running in the background.
Come on Lenovo, don't saddle us with additional bloat that actually impedes proper function of the **bleep** hardware!
And to PC Doctor, I suggest heeding the Hippocratic Oath: "FIRST, DO NO HARM"!!!!
Danny

Thanks for posting your fix...
I agree, ThinkVantage Toolbox has gotten pretty invasive as of late. It has also become less useful, although you can install custom add-on modules to make it better. Anyway, it is possible to keep the program installed w/o having all the background tasks. This leaves the Blue ThinkVantage button active.
Install TVT
Launch TVT, Settings, then untick "Enable Quick Hardware Check", Save
right click on task bar and uncheck TVT
run taskmgr.exe
Disable PCDEventLauncher, PCDoctorBackgroundMonitorTask, and SystemToolsDailyTest
PCDEventLauncher will most likely be recreated if/when you next run TVT- but it is of little conequence.
Also, are you are using AHCI? It is required for eSATA hot plug (+ some other features). We have had systems that refuse to keep a eSATA drive connected when running in compatible mode.

8703 typing random letters, can't use some symbols

For some reason which I cannot determine, my blackberry started randomly typing the letter "r" before or after about a quarter of the letters. These letters have no descernible pattern (ie aren't all located beside "r"). As well, some symbols don't work. For example, using "Shift-N" types 3n.

Hi and Welcome to the Forums!
Anytime random strange behaviors creep in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Best!
