Disconnects
 

Right whats happening on the NTL network have noticed lots of people getting disconnected on the network.

Is there a problem refreshing IPs, good reason for the question its happening to me now .

Re: Disconnects
 

Any updates anyone on DHCP release renew

Re: Disconnects
 

Ah. Does that explain why I have come home two nights out of three and had to recycle the power on the STB and the router to re-establish a connection?

Nige.

Re: Disconnects
 

is it just a local thing , i havent noticed anything up in teesside :confused:

Re: Disconnects
 

must be manc orientated possibly

Re: Disconnects
 

I have been getting this a lot, have to go to my router admin and do release/renew before I get any net connection

Re: Disconnects
 

Been a bit of work up there this week, so if this carries on over the next few days drop me a PM with your IP and I'll see if anything obvious crops up. What routers are you all using?

Re: Disconnects
 

Belkin only been happenng since weekend

Re: Disconnects
 

Linksys BESFR41, this has been happening for a while for me, perhaps a couple of months on and off ( usually in blocks of a few days )

Re: Disconnects
 

If you are having these problems are you on set top box or SACM also area

Re: Disconnects
 

i am on STB, tbh i hadnt reported anthing cos when i asked on here when it first started noone else seemed to be having problems, plus the fact that it isnt every day. I had put it down to some maintenance, or that my router was just playing up a bit ( well it has been on non stop for about 2 years, so its getting a tad warm LOL )

Re: Disconnects
 

That ties in with my view what area

Re: Disconnects
 

i am in manchester, NWish, maybe more west

Re: Disconnects
 

that again ties in with a idea that it may be DHCP on STB in MANC

Re: Disconnects
 

well any updates from any of our friends in CS or otherwise

Re: Disconnects
 

I'm having the same problem in Southampton. I have a Linksys BEFW11S4.
After the 24h lease expires it does not automatically renew - like it has done for the last year. I have to manually renew from the router's status page. Problem only been around for the last week.

Anyone got any info ?

Re: Disconnects
 

It is a real shame that we are having these problems seems to be Bromley Platform looking at the areas.

Bromley is usually reasonably good

Also STB related so got to be wonder if our DITV friends have been doing updates that change the BB config somehow.

Re: Disconnects
 

24 hours? mine always says it is '7 days'... would that cause any problems ( mine has always been like this, in fact when I first started on the trial it seemed like the lease was 2 hours, but reported as 7 days... as i found i would lose the connection every 2 hours, turned out my firewall was blocking the incoming 'renew now' message from the DHCP server...

Re: Disconnects
 

I have been having to reboot the SACM and Linksys router recently to get the internet back. It has dropped it while it was in use at regular times. Only the last few days.

Manchester area again.

Re: Disconnects
 

Linksys BEFSR41 working fine in Bracknell area - haven't had to reboot it for months. :D

Re: Disconnects
 

Be warned, the Belkin routers arent "High quality", I had two and neither of them worked very well and both had problems more than you described.

Re: Disconnects
 

Latest firmware has been no prob, with Belkin for months

Re: Disconnects
 

I think it depends how you use the belkin tbh, I used to keep all that up to date, but I know im the type of internet user that gives my connection a hammering, The belkin couldnt cope with that.

Re: Disconnects
 

Which model

Re: Disconnects
 

I've been having "Internet Connection Problems" for the past few months.....seeing this thread has given me a thought the renew could be causing the problems. I have noticed it more in the last couple of weeks - where the router and STB has had to be restarted....

I can't see it being the router (Netgear MR314 - Wireless) as I can ping and access the admin pages on the router fine.....just can't access the internet....

I'm in Portsmouth, with a STB CM.......

Can anyone official give a status ?????

Re: Disconnects
 

Which model of STB

Re: Disconnects
 

Havin same prob here.


Lease doesn't renew on its own????????? And when it does it isnt renewed for 24 hours sometimes.

I have notice my DHCP server number has changed so do I need to change that on my firewall settings????????

BTW.......SACM Salisbury area

Re: Disconnects
 

details for set up here

Re: Disconnects
 

Our box is currently a DiTV 1000.......

Re: Disconnects
 

Have just found this on the Netgear web site......sounds a bit far fetched to me....but you never know.....

http://kbserver.netgear.com/kb_web_files/n101208.asp

Re: Disconnects
 

Check this out here the 1000 box is more susceptable to changes in the power level . You may also find in the techs menu which can be found by pressing up dwn then blue on the remote that the disconnects are related to box problems.

The 1000 has not got the ability to adjust its levels as quickly as other boxes the 2000 is very good and provides a solid connection.

Also try to use other DNS than NTL the servers seem a bit flakey at the moment. Since i changed mine its been solid

Re: Disconnects
 

Do you have a firewall running when trying to release/renew. Firewalls often block dhcp acks as they are proxied via the ubr.

Re: Disconnects
 

For the past few days, i've been getting disconnects every 12 hours (according to my router), I live in Grimsby and my router is a Hotbrick 600 that i've had for a few months now.
This sounds like a DHCP renewal problem to me, help!?

Re: Disconnects
 

I heard of an ntl dhcp giving 3 leases (currently the maximum for standard users) of the same IP address, during the same time frame and to the same customer personal equipment MAC address. My mate couldnt get online, the ip couldnt renew because he already had 3 leases which shouldn't have happend in the first place because he hadnt changed adapter - it should have just renewed. :S

Re: Disconnects
 

why do you think this is DHCP - once you have an IP assigned - as long as you keep your connection, there should be no reason to lose it (unless NTL do some maintainance on the DHCP services) there will be entries on the log of your router when it re-sets saying that it is getting an IP address - but that is because of the reset - not necessarily the cause of the reset.

sounds daft - but is your router on a surge protected power supply - if not, it may be that the router is tripping due to a surge (I think eng mentioned this earlier in the thread as well). It could be that getting one of these power surge 4 ways will reduce the issues. (I got a surge protected 4 way from sainsburys the other day for £5 - and would always recommend putting IT kit on them ;) )

Just a thought...

Re: Disconnects
 

Well, it's bang on 12 hours, the router is on a massive ups along with my server so power is not a problem.
I think it is dhcp because i can't think it is anything else, the router log just says that WAN1 was disconnected and attempting reconnect (which it does do), then WAN2 gets disconnected shortly after (and reconnects shortly after). WAN1 is an ambit, WAN2 is a motorola 3100.
I forgot to mention it was a dual WAN router in my previous post (cost £500 so it better not have a fault!), both lines are 1mbit (and no, i do not use p2p software, i just want the speed when i need to do something quickly).
It has only started recently, so I am hopeing it is something simple, which led me to believe it is an NTL issue.

Edit: what is the dhcp lease time anyway?

Re: Disconnects
 

For the last few days I've found I've lost my internet connection. Checked my router and tried to renew the lease and get 0.0.0.0. Spoke to Tech Support? at NTL and the goon who swore he was not reading from a script told me my OS (xp) needed a system restore! After powering down STB I can get back on. The middle light stays on but the interactive dies!
Had fab service from my broadband for donkeys so I'm hoping this is a temporary drop in service quality. Have recently upgraded my wireless network from 802.11b Belkin router to 802.11g linksys and I'm hoping there is no link between this and the fault.

My 1st post here. I've wandered over from the .com graveyard. Good to find others here too. :wavey:

Re: Disconnects
 

Welcome to nthw :wavey:

You sound like another one of those people who would be better off teching your own faults. But of course you can't. ntl technicians dont read from scripts. If they did you would receive a limited service from the tecs with more experience and a better service from those with poor technical skill.

IF YOU FEEL THAT THE TECH HAS INCORRECTLY DIAGNOSED YOUR FAULT ASK TO SPEAK TO A MANAGER AND IT IS LIKELY THAT YOUR COMPLAINT WILL RECEIVE A SECOND OPINION.

Dont comment on something you have no idea about because you will be wrong and it just makes you look stupid.

/rant


If you have an IP address of 0 then the adapter is configured to auto detect from dhcp and the pc cannot detect the ip address being submitted - ie there isnt one.

If you are using a router the tech will have asked you to remove the router and connect directly to the pc. ntl do not support the teching of a connection issue when a router is connected - its 3rd party hardware.

If the pc is connected directly to the stb then it can be windows:
http://support.microsoft.com/default...&Product=winxp
http://support.microsoft.com/default...&Product=winxp
http://support.microsoft.com/default...&Product=winxp

This is why the tech suggested system restore - if it worked before a system restore will return the pc to its exact configuration before it stoped working.

Re: Disconnects
 

As my typing is so slow I omitted that I had removed the router and had a 168.*.*.* ip or is that 169..., can't rememer. Point is it was back up 10 mins later.

Fact is it was a network fault outside the LAN. The same one that happened today and yesterday. Definately not worth a system restore for. This was the 1st solution offered after a reboot. I used to do tech support everyday and employ people to do so now. If my staff offered that solution straight out of the traps they'd be called goons.

This is obviously an issue bigger than just me, perhaps the staff at the call centre should consider this too. I had only phoned to enquire if there was a current known issue then was drawn into a reboot, check IP again, sorry sir it's your computer it needs a full system restore. I made my excuses and left at that stage.

spiky ain't ya? Bad day on the phone? ;)

Re: Disconnects
 

I agree on that one, i'd probably try and back the tech into a corner to explain his actions and methodology behing doing so, putting the tech on the spot. System restore is a very good tool but is not a "fix", its a resoloution to a fault that cannot be fixed by the tech for whatever reason but may avoid reoccurance of the fault (if it works). Basically, instead of turning the customer away without resolution system restore gives them hope and if it works then the customer will have the impression that ntl fixed their computer.

The problem is human nature - every organisation has bad staff, ntl obviously no exception. Because of the nature of the technology a tech has to do a degree of leg work to find where the problem lies - on the customers pc, on the network or with ntl's device. The tech you spoke to obviously couldn't be bothered to tech you fault, blaming the pc is the easy way out and obviously works - you ended the call.

I dont know anything about stb so i'm not sure what (if any) ip address the box will give the device connected to it. I'm also not sure is the cmts records connectivity information for the stb.

What happens when you try and renew the 169 ip address?

You obviously havn't been able to give us all the information you can or a transcript of the call (not a critisim) so its difficult to judge if the tech was actually a mastermind or just lazy. Some 169 ip addresses will identify a fault with the pc.

Don't work for ntl. However i do work in a call centre and it instults me when people suggest that you (collectivly) work from a script and dont use initiative or their own brains. I know for a fact that ntl dont give out scripts and most of the stuff they know is from experience rather than taught.

Most techs will give a satisfactory level of support i would identify this as identifying the cause of the fault as closely as possible or try and supply enough evidence as possible to prove that ntl's device is not at fault. Allways get the name and extension number of the tech if you feel that you havn't received a satisfactory service.

Anyway, lets hope we can get to the bottom of your connection problems...

Re: Disconnects
 

Well must agree with people about the TS side, they tend to look for the obvious.None NTL problem thnk they have new people on STB support that are not up to speed yet found that out myself during xmas

Re: Disconnects
 

Exactly the same problem here in Norwich over the past few days.

My pc was disconnecting very frequently, but now its not
so frequent. I have not measured the time but I suspect
it is 12 hours like everyone else.

Re: Disconnects
 

Exactly the same as a CM, although using different IP ranges, so I'm not totally sure why there should be any greater difficulty. I'm working on it though. Could anyone experiencing STB drops and disconnections drop me their IP address or smart card number please, by PM? Thanks.

Re: Disconnects
 

Ime in salisbury area using the origional black bulky modems, and it has a habbit of disconnecting randomly - totaly randomly! The cable light on the modem goes out so it cant be any of our systems or network - BTW Using belkin router - log says:

If anyone understands that, their better than me!

SO it must be NTL!
Anyone offering a soloution?

Re: Disconnects
 

Re: Disconnects
 

If the cable light goes out, it is an NTL signal problem, which only an NTL tech can fix. It is unrelated to your equipment.

The router logs will not diagnose this problem. As a side-note, I think your router is over-sensitive: there are not any SYN floods in reality. If you can turn the feature of SYN-flood detection off in your router, then try doing so: it might improve your service.

Re: Disconnects
 

If using the belkin make sure that your firmware is at the latest standard, i have suffered from this flooding on my belkin but nowt like that do a check with spy bot or adaware to check you have no trojans on your PC

Re: Disconnects
 

No updates since this time last year!
I am seriously thinking of getting ADSL and a ADSL modem/router
Solve lots of probs!

http://catalog.belkin.com/IWCatProdu...duct_Id=113464

My router /\ at mo!

Re: Disconnects
 

you checked for trojans etc

Re: Disconnects
 

YOu dont soppose its due to i once tried to run a web host on my system? And i dont know what:

1970/01/01 00:13:48 DHCP Client : Send Discover

is? But more seem to be there!

My computers clean ime sure, i dont know about the other two!
I plan to reformat soon anyway!

Re: Disconnects
 

Just because you don't know what something means, does not mean that that thing is wrong or malicious. There is nothing in your router log to be concerned about, and reformatting your system will achieve nothing but waste a lot of your time. What is it that you are actually worried about?

Re: Disconnects
 

Trojans is what i am worried abot, And i like a clean out now and again! HOWEVER ime not really concerned! But thanks anyway!

Re: Disconnects
 

Is anyone still getting a disconnection problem?

I am still getting it in here in Norwich, and the solution
so for is to disable and then re-enable my network
icon on the PC.

After which it does seem to take a while to get
a valid ip address aclloacted by the DHCP.

Re: Disconnects
 

i have had ONE problem today, went for like 10 min!
