Very slow 0.16 mbps upload normal? Should I switch?

King Salmon

On speedtest.net I'm getting 12.24 mbps down but only 0.16 mbps up. This makes my CrashPlan backup take months and my Skype calls pretty choppy.

Is this normal? If I switch to another ISP, would I really get better upload speeds? Do the ISPs just use the same lines?

I'm assuming this is either ADSL or VDSL (fibre to the cabinet).

Although I guess it's not completely impossible to have a freak line that manages 12 down and 0.1 up, something appears wrong somewhere.

We have lines round here that only manage 0.2 Meg upstream because the noise margin on the upstream is so high even though the downstream margin might be normal. Without that noise, 1Mbps would be theoretically achievable.

The statistics from your router, most especially attenuation, rates, SNR data would be handy to see what's going on.

The other obvious possibilities are poor wireless signal strength (try Ethernet to be sure) and something else on your network uploading at the same time of which you may not be aware, consuming the remaining available bandwidth. But the router stats are a place to start.

I have an ASUS RT-AC66U router connected through a D-link DSL-320B modem. Have tested ethernet and am sure no other devices are consuming bandwidth while I run the test.

D-Link ADSL stats below. I have no idea how to interpret this; hope you can help.

That is a lot or errors, can you do a reset so the error count is zero and monitor them every few hours.

Your downstream Noise Margin looks high to me, so I'm wondering if you hear any cracking / noise on the phone line (you need to used a wired handset for this as DECT phones may create their own noise)? Ideally you should run this from the test socket behind your BT Master Socket faceplate (take out the two screws and gently pull the faceplate forward.. making sure not to lose any of the small coloured wires that might be connected to it).

Once you have your telephone connected to the BT test socket dial 17070 for the line test facility and choose option 2 from the menu presented ("Quiet Line Test"). If you hear any line noise like cracking, buzzing etc. then something is causing interference.

Out of interest, is your master socket using a filtered faceplate? Do you know?

I used to get this from my old broadband company - except your upload was my download at times. Horrible.

To me it looks like there could be something unfiltered if the voice line is ok or a filter could be on its way out.

Mark, I wouldn't worry about the SNR as its been upped by DLM and has IMP enabled quite high for it to bring the sync speed down so low.

Fair point Lee.

The line is prob erroring quite badly which is limiting the throughput also likely intermittent, the speed issue is just a symptom of something else.

I reset the stats, and after about 15 minutes the errors are at 65504, which I presume is the max it can count.

I don't have a landline phone.

I'm on ADSL. About eight months ago I had a lot of dropouts, periods of 3 minutes with no connection at all. BT sent a guy and he replaced some wiring outside of my flat and that seemed to fix the dropouts.

Is it worth calling BT about this? If I switch to a different ISP, would I have the same problems? I would guess so as it seems to be a line problem.

Getting BT to send out a man was quite difficult as you have to spend an hour talking to low level techs that keep asking you to reboot your modem. Any way around that?

First let us rule out your equipment when did you last replace the filters?
Your RJ11 is this the standard one that came with the router if so try buying a sheilded one they are dearer but they do block out noise from other equipment in your home.
Get your telephone line provider check your line winter months are bad for overhead lines.

What do you have connected to the telephone line? (thinking like sky box or similar)
When was this added try removing it for a wile see if noise levels drop.

You say you are in a flat does this complex have a central comms room before you get the phone line?

Finally how old is the router and have you tried a different one?

Firstly, you may or may not have a voice service or phone handset but that copper or possibly aluminium line coming into your home is still a line designed for telephones (even if today many only use it for broadband). The same rules apply, although I don't know how you'd get only broadband without the phone service if your ISP is BT?

Anyway it does sound a bit as if the line isn't being filtered properly. Have you stuck microfilters / splitters on all the phone sockets and are you plugged into the master socket or an extension? Also do you know if the socket you are plugged in to has a label on top or can you explain what it looks like?

The modem is plugged into a filter which is plugged into an OpenReach labeled socket that the BT/OpenReach man replaced for me. I do have phone service with BT but don't own a phone. There are no other devices plugged into the other sockets—do they still need filters if nothing's plugged in?

I really have no idea about my flat or my building's wiring arrangement, as I'm renting.

My D-Link DSL-320B modem is quite modern and only a year old.

As far as I can tell the only remedy I can try before calling up BT is replacing the filter. I've just ordered one off Amazon, so will try in a few days.

The socket you have the filter plugged into is it the BT master?
Does it have a lower part you can remove to reveal the engineers test socket, if it does then remove the bottom part gently as other sockets around the flat could be wired into it then connect the filter into the test socket. Once connected on the engineers socket take the ADSL line stats again.

No.14 on this page shows you roughly what Kits is describing (note: your front faceplate may have some wires attached, unlike the one in the picture, so just be careful and ensure none of those flick off their contacts by accident [usually not a problem]).

Yes, I removed the bottom part and plugged it in, along with my new Belkin filter. Errors still seem to be the same, maxing out at 65k in about 15 minutes.

Speedtest now says I'm at 0.26 kbps. Could be an improvement, or just a fluke.

Could you post your line stats from that position as that is the raw feed into your property any errors are then on BT network.

These speeds look ok .

SNR Margin (dB): 13.5 11.7
SNR margin still a little high might be worth asking for them to be reset for a fresh start see if they creap up again. High SNR slows the connection down normally.

Attenuation (dB): 9.6 5.5
This would place you close to the exchange.

Output Power (dBm): 0.0 10.0
I never like routers that give a 0.0dBm output power.

0 hec errors is good though from this position anyway things are looking better see if they will reset the SNR back to 6db you shouldn't need interleaving at that line distance but it looks like you have it on auto as it has corrected errors.

Have you tested the line for noise sure Mark.J posted earlier how to do it. Or remove the router from the line and call your phone line supplier asking them to check the line for faults.
