Another issue is that when an outgoing call is made via the home phone the internet cuts out completely and has to be reset.
Usually an indication of a faulty or missing microfilter?
Entirely possible but most of your issues are just down to a poor line.I was with another ISP a while back and there were some line issues. An engineer came round and speeds were up to 1.5-1.8 MB for a while. Then they dropped to just under 1 MB coincidently at the same time as I went above the fair usage for just a month. BT never managed to improve on 1 MB and claimed it depended on other users in the area.
Which indicates you are just too far from the exchange to get a decent speed.Changed to a different ISP and speed has been about 1 MB. Another line at home only shows 0.5 MB though.
A new router on its own is not going to help, you would have to get a new router and adjust the SNR on it, and with your earlier report line stats even if you could bump it up to near 2Mb it would be unstable and prone to disconnecting.Contacted my ISP a few months ago and they suggested a new router but I don't really want to do this. They're always very reluctant to do a line test or send out an engineer.
When the engineer came he probably reset DLM which in turn temporarily boosted the speed, no doubt within a matter of weeks to around a month is when it dropped as DLM would had realised at that speed you will not be stable.I'm sure the line is such that it needs to tweaking every so often by an engineer. If I used to get nearly 2 MB before then surely it's possible now ?
That is either a line filter as suggested by MissChief above..... A faulty phone/extension cable/wiring or if your Master socket is the new filtered type that is faulty/not filtering extensions. The other issue that could be affecting your speeds a little is the ring wire on the telephone extension if it is connected.....Another issue is that when an outgoing call is made via the home phone the internet cuts out completely and has to be reset.
Is the phone filtered? If so where is the filter? If not, then it should be. If the extension comes from the master socket and this is where the broadband is plugged in then does the extension plug into the phone side of the filter?
Do you have a filter for the phone? As you will need one for every phone socket being used in the house.
We're on a rubbish line here, on a Draytek 2860 we were getting line sync of about 1400 to 1600kbps downstream, connection was around 1.4Mbps.
Only by chance did I try another router (the BT HH we were sent) when I was doing some testing and noticed it was syncing higher, at about 1600 to 1700kbps downstream all the time.
Doing some reading seems that the Draytek whilst being very solid routers are rather cautious with the line and go for stability rather than out and out speed.
Draytek 2830 Release Notes said:For general purpose usage on UK lines, modem code 232201 is recommended
For ADSL2+ Annex M lines, the latest modem code 2471201 is suggested
For line speeds of less than 4Mbps, on lower quality lines a modem code
with more conservative paramaters, 211801 is suggested
I have a microfilter connected to the master socket from which the phone extension is connected. Should I connect a second microfilter on the extension cable and plug the phone into that. Is that what you're saying ?
Plugged both lines into the test socket. Didn't make any difference on one line but on the other line it went from 0.5 MB to about 1 MB. Does that mean I should get a new faceplate for this line ? I'm sure BT changed it a while back it was one which has really long screws...
NO do not double filter an extension. Place one filter on the extension either near the Master socket or near the phone/extension socket.
OK
What do you mean both lines? connect only the modem to the Test socket. Do NOT connect the modem to extension and then test socket, that will unlikely make any difference.
I have two broadband lines in the house that's what I meant....
Me personally for what may turn out to be even be less than 1Mb improvement i would not bother spending silly money on a new modem/router.
