Why would speed have dropped?

Go to solution
Until about three months ago I was regularly getting a download speed of 13mb. Now I am getting about 9mb which represents quite a reduction. Nothing has changed internally and my set up is the same as it ever was. Here are the current stats. from my router. Is there anything obviously wrong here as this information means very little to me? Thank you.

Line state: Connected
Connection time: 0 days, 09:42:16
Downstream: 10.74 Mbps
Upstream: 1.121 Mbps

ADSL Settings

VPI/VCI: 0/38

Modulation: G.992.5 Annex A
Latency type: Fast
Noise margin (Down/Up): 14.5 dB / 5.7 dB

Hi

Welcome to the community forums

 

Your speed has dropped  because of disconnections / noise on your line increasing your noise margin

your connection speed is lower than normal due to the high noise margin as normal about 6db.  your connection time is short is that due to you resetting the router to try and improve your speed or the router dropping connection or both?

 

are you connected to master or preferably the test socket?  do you have other sockets in other rooms?

Thank you. My router is plugged directly into the main socket (I do not have a test socket). I have one other socket in the house but it is not in use. I had just restarted my router which is why the connection time is short. I have a very reliable connection generally and never have problems connecting for long periods of time. Just odd that over the last three months I have seen a reduction in speed of about 1/3. Quiet line test is absolutely silent.

check to see if bellwire connected to terminal 3 and if so remove it from both sockets - only connections required are on 2 & 5

bellwire removal

restarts are the worse thing you can do as this can increase noise margin and reduce the connection speed

Looks like bell wire already disconnected.

then just stay connected and repost stats when connection time is 3+ days and see what errors are like.  if still ok and connection stable then can get mods to reset your noise margin back to 6db
