Wireless keeps dropping - Multiple T3 errors

My wireless connection keeps dropping for a couple of seconds every 10 minutes or so which makes playing games online and streaming videos practically impossible. I went on the VM status site and when running a test on the broadband, i got the below message. I've been getting this for about a week now.

I've looked at the router status and below is the outcome.

Haven't got a clue as to what any of this means but i've looked up the T3 errors and they have caused people to have the same issues as i'm having. Can someone have a look and see if any of these is abnormal??

Re: Wireless keeps dropping - Multiple T3 errors

Your upstream is running a tad warm to say the least, and is probably the cause of the T3 errors, especially if the upstream power is fluctuating.

However, this does not mean this is the sole cause of the dropouts, you could be experiencing wireless interference as well. If this is the case, then changing the wireless channel can help. Downloading a wireless scanner like InSSIDer would help.

However, I would wait until any upstream impairments are resolved before diagnosing any wireless problems in detail.

You will need to contact VM to take a close look at your connection by, either by waiting here a few days until a VM Forum Team Member picks up the thread, or give them a call on 151 from a VM line or 0345 454 1111 for a quicker response.

Re: Wireless keeps dropping - Multiple T3 errors

Hi hamzer, 

Thanks for the post! I am sorry to hear about your issues with your broadband having T3 errors. I apologise for any inconvenience caused.

I have tested things from here and both of your upstream power levels are too high, an engineer will need to attend and investigate this further for you.

I will send you a PM (purple envelope at the top) detailing what's required to proceed with making the booking. Please respond to me there and I'll get this sorted for you.

Take care, 

Thanks,

Adam.
