Hi guy's this may well be the wrong sub forum but thought it might be the best place to get replies so sorry in advance.

Basically we have had BT infinity in the house for the past 6 months or so and it has honestly been great so far. However the past few days we have been having serious issues with it working.

One minute the internet's working absolutely fine with 37 mb download 10 upload speed and the next minute its unusable with download speeds as low as 400kb and then the next minute it will be right up again.

this is highly irritating while gaming as my ping will jump from about 32 up to about 500-2000...sometimes as far as 30,000 and then suddenly it'll be all fine again. But this never lasts long...about 5 minutes at most before it jumps back down again.

Just wondering have you guys had any similar issues and if so did it sort itself out or is it worth getting BT out?

Cheers.
 
Would suggest to me something locally - someone else browsing the web at your end? some application you have running in the background thats periodically doing something online?
 
I did read a review of wireless card performance and that was how performance was described in some cases. Are you wireless, have you tried wired?

It is the wrong sub-forum of course.
 
Nope, nothing unfortunately. we have 3 pc's connected but nothing doing anything intensive.

Edit: doh yeah i missed the networks forum, sorry if dons would like to change it its no problem. Sorry.

And yep wireless.
 
I've seen reports of wireless performance varying, despite there being no reason at all for it. I believe it was a review of network cards for laptops fairly recently...
 
Well they are all laptops that are connected to it however they all have wireless N cards in them and they have alll been working great for the last 6 months or so which is rather weird.
 
Its possible someone else is now sharing the wireless frequency (the application inSSIder can help check that) or something has changed software wise on the laptops.

While its not definitely a local issue it sounds more like it than a BT network one.
 
Okay guys this is my winMTR reading:

I'd say wireless issue personally. If you're gaming, grab some OC value home plugs or run a cable if possible.

As great as wireless N is for speed, latency is still not great and can cause these issues.

Things that effect it are placement, microwaves, cordless telephones etc.
 
Right guys ive used that inSSider program and noticed a correlation between the high pings and a drop in amplitude. Any ideas what could be causing this...screenshot down below shows it where the arrows are pointing.

Okay never mind, still getting spikes while the amplitude stays the same.

Do you have an Android phone? Download wifi analyser. Shows you which channels are occupied.

To be fair though, ditch the wireless anyway if you're gaming - its just good practice.
 
buy a £15 50m network cable. (or plug something in closer to the router)

this will bypass the wireless

fair chance its just a line issue and the cable will prove it.

report to BT

You just need to get decent wireless :cool: I see at best 1ms difference in pings on wireless vs wired, maxs out my 80/20 no problem, plus i've the 5GHz band all to myself :p
 
I game all the time on wireless and I dont have any problems providing the connection is ok. Only thing I have are drops in speed, which are restarted by restarting the homehub. I have been thinking of getting a better router recently though.
 
Another idea, when the increase in ping has occurred, have you actually tried pinging your router's IP address ? if you are get a low ping then it will rule out any problems due to wireless connectivity. If your not sure what your routers IP address is, then go into command prompt and type in "ipconfig /all" and look for Default Gateway.

If this has already been resolved, then my apologies.
