Help. how good or bad are these stats?

pauld

I have a zyxel prestige 600 series modem and a dell broadcom wireless router. The router is constantly disconnectin, has been doing this for months. Someties the dsl light goes balck, other times the 10/100m lights goes blank and sometimes the ACT light goes. No matter which ome goes blank, the internet connection is lost.

The stats are below:

would purchasin a new combined wirelsss router help. I am on BT, supposedly 7.6mb

thanks

They're poor stats, a max of maybe 4.3 megs or so max.

pauld

spear thanks that ties in with spped test I have done before. Do you reckon a chnage of modem/router would reduce the level of disconnects?

Your line is about 4+ kilometres long, which causes high signal attenuation, making it more susceptible to noise and desyncs. Some routers can deal with it better, but a lower package, 3 megs or so would give better stability.

pauld

spear thanks for that. I was hoping not to downgrade. i will try the new router/modem first and leave the "nuclear" option as a last resort. Interestingly it seems worse between 6pm and midnight! just suffered a another 45 minute outage with no light on the 10/100m light on the zyxel however dsl light steady green and the ACT light steady orange.

Your line is really not capable of the speed you are on. the more you increase speed the greater the pressure on the line. Probably BT should never have given you that line.

However have you anything else connected to the phone line in the house? If so are there filters etc etc Is your phone line connected to the main socket or to an extension?

do as much detective work as possible before splashing out on a new router as the new model could even disimprove on your current performance as not all brands are great with iffy signals.

Have a read of this for some further information.

Dub45 thanks for that, I have had broadband for 4 years, the problem only really started after the automatic speed increases were put through.

I think I will go for the downgrade first and see if we can live with the slower speeds. We are not heavy users, the kids like the RTE player, I am assuming that would still work well on a 3 meg line?

Can we see your sync rate please - 192.168.1.1 > System Status > Show Statistics.

We need your downstream and upstream speeds. Thanks!

pauld

cpu-dude, not being tech savyy, i thought they were the stats I provided in my first post.

I rang BT to downgrade and the guy asked me a a few questions. His diagnosis was that because I was on a "BT LLU ADLS2 exchange, my anicent prestige router could not handle it" He advised he would send me out a new BT Voyager router (for free) and that should do the trick.

They were but via a diagnostics, there is another section that shows your sync rate.

Ah thats great news, a lot of them older Zyxel routers aren't ADSL2+ compatible.

Dardania

A contributary factor may be that as everyone got their speed increased, there's a higher level of attenuation from cross-talk on the dsl enabled lines from your exchange...which corroborates with you experiencing problems in the evenings...

In the mean time you could check the prestige site to see if there have been any firmware updates. A lot of companies issued adsl2 updates via firmware so might be worth a look.

I'm having the same issues. BT 7.6MB line on the Bettystown exchange. I''m also having issues in the evenings mostly with DSL Sync dropping. Would I be better downgrading?

And the Speedtest results:

Dub45, I have never updated the firmware since I go the router (it must be 4 years now!) I know that this isn;t very bright on my part, just never occurred to me.

I will have a bash at it tonight,

Its irrelevant on those older Zyxel routers, it's hardware only allows ADSL connectivity, not ADSL2+,

Your line stats show that 7.6MB seems to be a bit too much for your line, if you ring BT - ask them to drop your profile to 6MB. This way you will have a stable connection and the full 6MB speeds.

pauld

cpu-dude, ok I will leave it so and swap over to the voyager when it arrives.

thanks

Paul

Petetheroadie

Thanks CPU Dude, I called them and after some lengthy tests with me on hold have dropped it to 5 meg for now. If it holds stable at 5, they'll up it to 6meg to see if it can handle that.
