120M : Very slow downloads, have I been capped?

[Krudo]

Hello,

OS: Windows 8 x64
CPU: Intel (4th Gen) i7 3.50GHz
RAM: 16GB

I recently updated to the Super "Dooper" Hub #2 and since I have been on this service my connection has dropped to a crawling pace. The engineer said to be before he left. If you get any problems with the connection, give faults a call to make sure that they've put you on the right part of the network. I must admit, this has happened before and they messed up my connection, until I spoke to somebody who was knowledgeable to understand that somebody had made a mistake. I hate calling faults because... I always end up speaking to dumbest of them all who is obviously reading from a scripted questionnaire.

Well my connection at the moment has a Speed Test of 5MB. This is a 120MB connection and the speeds that I am getting are appalling. Before my Supper Hub was changed I was getting amazing download speeds. But now I have noticed they are appalling slow.

An example: Downloading Assassin's Creed 3 from Steam on my old modem was as shown below. These are accurate speeds and not factorial, these were logged at the time of the download and continued throughout.

Super Hub #1
Current Network Usage
7.9MN/s Download Rare
11.9 MB/s Peak Download Rare

Super Hub #2
Current Network Usage
1.8 MB/s Download Rate
2.6 MB/s Peak Download Rare

I ran WinMTR for about 4 hours, and the packet loss was minimal apart from one section which was 89% PL but then it started to drop and average out about 27% PL and it's now rising up slowly again which is normal depending on how many active connections are on at one time. it's leveled out at 32%.

Packets
PS: 193
Rec: 148
Loss %: 24

Ping time
Last: 37.0
Best: 19.0
Avg: 33.0
Worst: 98.0

I know that my connection can download this game in less than 50 minutes. but on this new Super Hub the download speeds are just utter rubbish. Oh before I forget. Power levels on the modem are perfect -5.46dBMv which is fine.

It looks as though I may need to speak to faults about this. my connection is so slow I may as well be paying for an ADSL connection. I have downloaded some 400MB files from my server and these are slow as well. I have downloaded some large files from various websites and these are slow as well.

I tried the SH#2 without the CISCO router attached and the connection was the same. At least I know the problem isn't with my equipment.

While within range, that's actually far from "perfect". What are the full stats to your modem? For every channel, up and down - we need to see the lot.

^^ What he said. -5.46 is barely 1/3rd of "perfect", though not exactly Sum Ting Wong/Wi Tu Low material either.

Here we go, I have compiled other data as well just in case you require this as well. If you need anything else just PM me.

Everything was fine until the 15th of this month and then it just went... Pete Tong. and the downstream PW was the same as it is now. I'll change the Forward Path Attenuator tomorrow to lower the PW...

The downstream power is too low and your SNR is too low. Poor signal would appear to be the source of your packet loss and consequently low throughput.

Okay, I have been using CISCO routers for years and I have never know them to be sensitive to router names...? Because you cannot put a space in the center of a two worded name. I put a - which I think threw the modem into Numpty Mode because changed the router name without spaces or - and also left the Local Network Host Name as default and now the download speeds are back to normal. I ran a bandwidth test and I am now hitting what I should be hitting. So testing the SH#2 was down to me not rebooting the cable modem, so I have put that down to cache.

I know this is probably a long shot but it has resolved the hideous download speeds. I just downloaded TC Ghost Recon FS, Metro Last Light and Sniper Ghost Warrior 2 and the results were.

Current Network Usage
15.5 MB/s Download Rate
15.5 MB/s Peak Downloaded Rate
24.2 Total Downloaded (DLC Packs increases TD)

HAAPIS: Happy as a ? "I'll leave the rest to your imagination."

I never want to go through that again.

There has always been a borderline between people saying too low and needs to be higher for DS ideally between -1.5 and -2.5 is ideal depending on which part of the network you're on and which part of the UK you're in.

Ideally Newport West for example -5.6 isn't that bad -10 would have consequences on the connection and -15 would cause the modem to power cycle all the time.

The SH2 isnt Cisco its Netgear.

I know, Mine is set to "Cable Modem Mode." I have a CISCO router which I use instead of the Netgear. To be honest... I'm not a fan of Netgear routers, their paranoid and give you false results. I'd trust CISCO over Netgear any day.

My 120/12 is terrible slow all weekend and all day today. Engineer been here today swap new superhub and he checked everything say 34/7 is fine as it was suppose to be up to 120 and up to 12 and he say there is nothing further he can do about it.

nice downstream power, the tech who visited is what is known as an idiot

[Kushan]

Yeah, 17+? That's a joke.

[telfordcable]

The tech is a female (not surprise me) they re-booked me a 2nd engineer come out tomorrow urgent!

i bought myself a Netgear WNDR3700v4 the other day and i cannot fault it.

[telfordcable]

Tech Man been this morning and now fixed power level is that power level look ok now?

[Kushan]

They're still not great to be honest but they're in line.
