DSL to VDSL/ADSL - BT Openreach socket

Hi,

I am trying to find a suitable replacement for my BT Business Hub 5 (same as BT Home Hub 5 apparently)...

I have this on the wall (BT Openreach box):

And this is what I have on the back of my BT Business Hub 5 (DSL & WAN, I connect via DSL):

As you can see I connect via the DSL cable.

The problem
The issue is that the BT Modem/Router (the supplied modem/router) looses connection frequently, especially if I put it under load with FTP and some games (I am now on my 2nd BT Business 5 Hub with same result).

Possible solutions?? What do you think?
I am looking at either the "TP-Link AC1900" or the "DrayTek Vigor 2860ac" ...

Option 1: "The TP-Link AC1900"
The "TP-Link AC1900 Wireless Dual Band Gigabit VDSL/ADSL Modem Router for Phone Line Connections" looks to be a better option over the DrayTek as it appears to have both dsl and vdsl/adsl connectors, is this recommended modem router combo? Is there better? Is this good for when BT finally upgrade the network in my area? (planned for Jan 11th 2097)?

Option 2: The DrayTek 2860ac
This appears to only have a VDSL/ADSL connection, no DSL connector, but I hear it's the best?

Would an ADSL filter (see pic below), plugged into the phone line out of the BT Openreach box (1st pic above) allow me to connect the DrayTek via the VDSL/ADSL? Does the BT box already split the connection from the phone? or what I think is that I should get a DSL capable modem/router combo?

Any advice or opinions are welcome.

Thanks

did they check the lines from the pole to your house/business?

did you replace the lines from the line drop on the side of your house/business to the modem (as a test) ?

i ask because a friend had this happen (with comcast, yes cable internet, the issue was the same as yours) and they claimed to have repeatedly check the lines from the cable drop to his house. as that was an underground cable and not pole mounted, and attached to a box on the curb from his house, he ran a NEW cable on the ground to his house. problem solved, once demonstrated to the tech that this solved the problem , then they were forced to run a new line.
moral of the story: the ISP will not put any more effort into something if they can show something "tests good" , even if it is in fact failing.

With Frontier I have gone through 2 DSL modems. One lasted about 2 years and the replacement started failing after 6 months.
Once ever few months we lose the Internet and there is a red light on the modem. No biggie. When it happens every week it is a problem and Frontier has been fantastic in replacing the modem.
One thing I found is that some phone jacks in my house are better then others. Whoever installed the phone lines ran some of the lines wrapped around the AC power lines which is a problem. Switching to another phone jack made my Steam download speeds go from 250 to 400 kbps.
My house was built around 1900.
In my area the cable Internet company is Service Electric Cable so Frontier does have to give good service to compete against a cable ISP that has a legal "fiefdom" to my area.
Even if you want to buy your router I would call your DSL company and ask them which one they think is the best unless they are also the local cable ISP.

Everything is lamp post based here, but they said they have done a deep line test (whatever that is), with no faults found.

Just carried out the following tests (amazed it got through the small file test, as it didn't last week)

Test 1: start @ 15:49 - 3 uploads of 240mb - FAILED @ 15:53 - 17.3% (CONNECTION LOST)
Test 2: start @ 15:59 - 3 uploads of 240mb - FAILED @ 16:02 - 14.7% (CONNECTION LOST)
Test 3: start @ 16:05 - 3 uploads of 240mb - FAILED @ 16:09 - 19.5% (CONNECTION LOST)
Test 4: Small file upload test (wordpress x 10) - start @ 16:13 - SUCCESS!
Test 5: Small file download test (wordpress x 10) - start @ 16:29 - SUCCESS!
Test 6: Large single file upload of 1.4GB - started @ 16:44 FAILED @ 16:48 (CONNECTION LOST)

Yes, I do get single wordpress websites to work on which are 100k+ files, thus the 10 x wordpress upload in a single batch test.

So it looks like my connection fails on larger concurrent file transfers, on friday gone it was going down by just using GMAIL.

ADDED

Additional test just carried out:
3 x instances of Ubuntu downloading at the same time, no disconnects.

If I call an engineer out and they find no fault they will charge me £240.... Also as and when my connection is really unstable is a bit random, it's always at its worst on the weekends, but an engineer could turn up and everything may be solid as a rock and I will get charged for it...

ADDED

Don't know if this will make sense to anyone but here is the router log for a fail test:

Step 1. Clear log
Step 2. Start 1.4gb file upload
Step 3. Wait for disconnect and reconnect
Step 4. Export log
Step 5. CTRL V

Are you on fibre speeds or just normal ADSL speeds? What are you paying for?

"DSL" on the HH/BH routers do mean VDSL/ADSL. The draytek will do both fibre VDSL and copper ADSL.

You should also be able to test the line by pluging in a corded unpowered phone into the bottom socket of your master socket (the open reach box is your BT master socket), and phoning 17070 to do an automated quiet line test. Any noise on the call would indicate a possible problem withe the line not within your boundary.

Is your master socket made up of three parts? (front bottom face plate, middle face plate, and backing plate?)

Your HH/BH, does it have a plastic all white wifi info card or a black one with white front?

The Draytek is definitely superior to the TP-Link in pretty much every single way.

I use a Draytek 130 which is basically the modem only part of what you've looked at, its rock solid.

I got the fiber package but it's copper for the last mile to the house, so I got old school DSL, 1 to 4mb up and 25down. it runs at less than 50% what it should be due to not having fiber to the door.

I am on the phone with the BT Engineer now.... He just told me this.... Note this is a Business Line...
"The problem is that your uploading files which are too big, you can't upload files of that size, as it's too much for your connection to take"....

1.4GB single file....

Used to upload 3.4GB files with no problem before but all of a sudden, anything over 200mb is too much for my line? WTF lol

Your thoughts?

Make sure to make note of the time of the call, and if you have it, the name of the engineer.

Your log you posted suggests its connected at around 29Mbps which is fibre (copper last mile, but its still classed as fibre to the cabinet).

So you should be getting up to 30Mbps which I imagine is the package you got.

What the engineer is saying it a load of crap to be honest. Sorry hes talking shit.

Does it disconnect if you're not doing anything?

Being VDSL eliminates one of the cheap tests i was going to suggest.

If you can answer my other questions once your done on the phone that would be super useful.

If you get no where over the next few days PM your info and all the info you have and i'll see if I can escalate it.

edit: uploading to the point of saturating your upload can negatively impact your download

Ye I agree with you, complete BS...

I can get it to disconnect every time I do an upload of 1.4GB, it gets to about 25% or less and will disconnect. Same result with 3 x 200mb files.

Yes, it does often disconnect when doing nothing, especially on weekends. On friday gone it was disconnecting with playing an mmo and using gmail. But is a lot more stable in the week? Too much load on the lines? Not enough bandwidth in this area?

RE: Uplading to saturation..
When I need to upload files of that size, I usually do nothing but that, but when I need to, I really need to for work. I have various projects which are 2.5 to 3.6GB Adobe AIR projects which I have to compile. And when client goes, need a change, I have to compile and re-upload again, this can happen a lot (clients).... But never had a problem, just takes a long time (lots of tea drinking).

Been on the phone for over an hour now... I'm getting transferred to someone else...

What I hate about the current method of solving problems is they essentially threaten you with a hefty bill to come out if they find nothing, which is horrible as I think its just there to stop people calling out engineers for real issues. Especially when the people billing you are the ones deciding if its your fault or not.

How much bandwidth do you normally use? I would honestly consider alternatives (as much as i probably shouldn't) AAISP for example though a little more expensive essentially guarantee good service and will fight openreach for you to fix any line faults (they know the tricks).

edit: also, i assume this is all on wired connections the testing and disconnects are happening on? (no wifi as it has its share of issues that can contribute)

Call just ended with (Stephan - 1 hour on mobile, 15 mins ish on landline), with him trying to transfer me to the "Legacy Team", whom he couldn't get hold of. Apparently they will call me back within the hour...

Ye, I hate the £245 +VAT engineer threat, I keep getting told that all the time...

AAISP? BT Business already costs quite a bit, the advertisement on the website and tv etc just says the price of the broadband, no line rental or charges etc... I'm currently paying £52 per a month..

RE: Bandwidth
I play netflix a lot (often when I'm working), but other than that it's a bit of youtube at 720p, mmo here and there, i don't stream music (pref to work in silence these days).

I have 1 work machine connected via LAN to the BT Business Hub 5 which is directly connected to the openreach box (now screwed the front of the box off - engineer requested I plug it into socket inside direct via the adsl spliter).

Could be a good time to find another ISP like you said... Well worst case scenario I can always use my mobile to upload files without disconnects, will just take even longer.

EDIT: Bandwidth
Note, I don't have netflix or youtube or online games playing when uploading, I also avoid skype during this time also (I only run skype on request).

Just have to wait and see, hopefully you do get a call back and get some movement on it.

It's always worth checking your options now and then, your ISP is no different. AAISP for example are generally quite good, but they are a bit more specialised (dual lines, IPv6, redundancy if required, etc. etc.) and do have quota limits being a small company, but generally provide a good service and will even take faults you currently have and solve them for you if you move to them. (I don't use them, but thats because I don't pay for broadband).

In either case. In the long run your better off with your own equipment for two reasons.

  1. Its yours, and if not manufactured in the UK, isnt subject to the new UK laws that can force companies to compromise your equipment for access.
  2. It generally works better compared to any ISP equipment. The reason i asked about the wifi card thing is because there's two HH/BH 5 versions, both have their issues. Draytek for example make fairly rock solid equipment. I Run a Draytek 130 modem into a pfsense firewall on to my network.

The downside of your own equipment i should mention, is you have to manage it, this being mainly updates. But I don't see it as a downside, ISP equipment if updated is updated remotely without your permission or knowledge. Better to have control of everything on your boundary.

Just got off the phone with the Legacy Team (Lady), she noticed that I wasn't showing as disconnected when she got me to unplug my BT router, so maybe an issue there... But she has organised an Engineer to come out and trace the fault back to the exchange.

Just lost connection as I was typing this lol, nothing going on other than this web page... No uploading needed to take me offline there :wink:

I have a vague memory of this being mentioned before, but was years ago, thought it best to stick with, "if it's not broken, don't fix it"... Maybe something to do with it.

Will know sometime Wed....

I Might just order that TPLink now so I can remove any BT Router doubts, I don't think the DrayTek will work with my old DSL connection (is DSL, ADSL? just missing the A?).

Your not on "old DSL" your on VDSL. "DSL" isnt a thing its a group of DSL technologies, one being ADSL, your traditional all copper connection "up to 17mbit" and VDSL fibre to the cabinet, copper the last mile, up to 70mbps. (there are others as well but BT sells those two mainly)

You get 30mbps, your on VDSL so need a VDSL capable modem. Anything that says "DSL" usually does ADSL, VDSL or both.

That said, TP-Link will do the job, and its cheaper. I used a cheap TP-Link ADSL modem before I got fibre (FTTC) and got the Draytel ADSL/VDSL modem.

Sounds like they've an idea of where the issue might be, keep a note of everything and details. When and how often its disconnects is useful too.

The slow downs at peak times is probably unrelated and just due to congestion in the area.

Well BT Engineer has been and just gone. I was connected via a Residential line and someone somewhere else out there was connected via my Business line... This has been fixed now...

As for my issue...

Ran an upload test of 3 x 200mb files while the engineer was here and it failed both twice infront of him (nothing he can do - all is good on the line etc now).

Sooo... All I can do is wait the 10 days for the line / exchange / god to settle and balance themselves and see if it's ok then. At the moment I've lost 8mb on the down, upload is the same and ping is in the 40 to 50s (was 20s).

Meanwhile if I need to upload anything of more than 200mb and the server doesn't support resume, I will use my mobile 3G tether....

This is apparently more common than you think. They will swap lines to test them for issues and sometimes forget to put them back.

If its not an issue on the line maybe its an issue at the exchange. The fact that its failing on both lines suggests its possible. Do you have a neighbor who could also test?

Have you tested uploading to other servers in other countries?

Yep, tested on hosts which have data centers in the UK and US, same result.

I do have a neighbor that I can test with also but different ISP (talk talk or sky I think).

I've tested a 1.4Gb upload on my THREE mobile tether and it was fine, just took a very long time, no connection drops.

You shouldn't be getting those disconnections. It could be an intermittent line fault somewhere, or a misconfiguration.

Are you 100% sure there are no other phone extensions/equipment on the same line? If there are try unplugging all the other equipment (phones, fax machine, alarms, credit card machines, etc). If the wiring hasn't been done properly, using another device could cause the xDSL to disconnect.

From your log, it looks like the exchange end is telling your router to disconnect ("PPPoE PADT received"). Google that term and you'll find the problem is not uncommon, and various solutions presented (eg reduce MTU size, configure NTP on the router, remove the "Service Name (Optional)" field in the PPPoE setup. However, I'd check all the cabling first.

500% sure, only 1 socket in the house and it goes straight to the router and phone (see 1st post and pictures 1 & 2)

Problem is with the BT Hub, you have about as much configuration control as you do with a paper weight...

I will wait the 10 days, see if it's stable and if not buy the DreyTek modem/router/firewall combo, if that don't work then I will have no choice but to try another ISP.

Thanks for the info on MTU, NTP etc (no idea what they are but guess I will if I go the DreyTek route)...
