Technicolour TG582n Router

I have noticed that BE/02, talktalk, tescos as well as plusnet use this router. I can buy one of these cheap on ebay, so if I did go with plusnet, I won't be paying £40 as it don't have great reviews. http://www.amazon.co.uk/product-reviews/B005ELFTH4/r...

My question is, can I flash the TG582n with either generic firmware or isp firmware say from plusnet?


So if I buy a BE/O2 version, can I flash it with plusnet firmware?

They may have locked them down for some silly reason, but the router that BE supply is only on loan not sure if o2 is the same

Yes I remember years ago with BE that you had to send the router back when you left. Or you had to pay if you wanted to keep it.

Only thing I found about this is here http://forums.modem-help.co.uk/viewtopic.php?p=16958 but does not answer my question fully.

Plusnet supplied me with a 582n FOC.

It has Plusnet firmware but I don't think this very different from the standard firmware.

I also have a DGN2200 which Plusnet supplied FOC a year earlier, and does not have any branding.

You can learn about these things on the Plusnet forum.

Firmware upgrades for the 582n are not readily available (they can't be downloaded from the Thomson/Technicolor website). The router is designed to be supported direct from your ISP who can connect to it using a special server to update firmware (that the ISP can obtain from Technicolour as a partner company). No idea if you can get decent third party firmware for this router.

If you want to tinker with the router are need advanced features (like QoS, VPN) then look elsewhere as this is a pretty basic domestic router.

I've just installed the Zen version and it's been fine (although only been in use for 1 day). No significant difference from my previous Thomson 585 v7 router except that Zen will actually support this one.

The wireless sucks aparently as reported be several BE unlimited customers, I have one ,don't use it though, my personal opinion of them is they are a POS router, that belongs in the bin, probably why they are the choice of some ISP's that and price as well as the built in backdoor , but they are a pain to configure port forwarding too, I don't wish to spend hours configuring a router , the netgear is very straighfoward, as are the billion 7800n now there is a proper router for you

I also received one of these routers from Zen, free of charge, as a result of signing up for FTTC broadband.

I'm glad that I did not pay for it as I am very unimpressed - probably only worth £10 - £15 as a bargain basement quality router.

If you want a basic router to plug in, leave on default settings and forget then fine. However, if you want to change settings then, I'm not so sure.

Zen supply it with their own version of firmware which offers choices to use as an ADSL modem/router or WAN router for connection to the Openreach modem. In the latter configuration you lose the 4th ethernet port to use as the WAN connection.

I cannot change the default DHCP range and gateway IP which Zen have pre-programmed AND successfully access the internet. Also, if powered down overnight, it occasionally "forgets" device settings which I have nominated (i.e. nomination of static IP allocation and port forwarding).

As I have just gone live with FTTC this weekend, I'll live with it for a few weeks but fully intend to purchase a better quality router in the near future. I'm looking at the TP Link 1043 gigabit router which gets good reviews for the price.

Ditto that for Plusnet. I had to change my private network addresses to suit. Not a massive deal, but I would prefer to have the freedom of thought.

TR069 as in the backdoor is a very common standard these days

I was looking at this TP router version. Not bad price http://www.amazon.co.uk/TL-WR2543ND-450Mbps-Dual-Ban...

Agree about 15 quid is all the TG582n Router is worth. Not £40.

You always used to be able to get firmware when it was thompson. I did it myself.

I also ment using say, Plusnet firmware that you can get hold of and flash say an O2 version of it.

But like you say it's not a great router anyway

The wireless sucks on all of them from what I have read up on.

Yes I was looking at billion and may go for one of them but can't make my mind up at the moment.

Not that much on PN about it really. They certainly don't tell you if you can flash it. Not worth £40 if you can't. It will just be an expensive useless brick.

Be unlimited use a different somewhat hidden method, it can be disabled if you want to mess around in the cli via telnet, As far as i'm aware there is no config /set up within the user GUI for TR069 like there is in most routers , But the TG582N fails on other things also,

Why the dogged persistence that the router costs £40, it only costs that if you leave Plusnet in the first 12 months.

My Plusnet version allows the network, IP address and DHCP parameters to be changed. It is very much the same as my 585v7 with unbranded firmware.

Right I bought a 02 version of the TG582n Router to see if I could flash it to work on another isp. Well not a lot of luck but some things that may be of use to others. I also called thompson but will post separately about this later.

Here is a snapshot of the o2 router main page and firmware installed. http://s6.postimage.org/5m28dc2v5/o2_router_E.png

I downloaded many files from modem help and tried about 3 different thompson update utilities. Still no luck. First I got stuck on the login screen while trying to update. It's not your normal username and that's why it would not work. You need to use SuperUser and serial number as password. This should work in most cases.

I tried to update the router with many plusnet firmware but it says, it's not compatible.
http://s6.postimage.org/5nc66r4ox/o2_router_firm_not...

I found a post on another forum that said you can FTP into the router. At first it failed. That is because I did not use, SuperUser. Now I have never really done ftp into a router and don't know what I am looking at or what you could do to get the router to work with any isp. So see the snapshots and that may help others to crack this issue, who are a bit more clever with this router.

http://s6.postimage.org/7tb2ezxj5/o2_ftp_page2.png

So I have still not had any luck with this router but maybe someone else can hack it or maybe able to use some things I have found out. Think I know why it may not work with this router though.

The router has a USB port so it maybe possible to hack it that way.

How about:

http://wiki.aa.org.uk/index.php/TG582N#TFTP_Firmware...

I don't see what FTP in itself will achieve. Perhaps TFTP?

Never tried that before. That is also for AAIP and so may not work the same with other brands.

I called thompson the other day to ask about a few things.

I asked why no firmware options on the website like you used to get. I was told that the licensing has been changed and they only deal with the isp's, so that is why you can't download firmware anymore from thompson.

I asked about generic firmware so I could flash my o2 router. I was basically told that, there is no generic firmware. So I said, how come amazon is selling a generic version of the same router. The reply was, it must be for one of the isp's as they don't sell generic version to the public.

So if anybody has bought the TG582n Router from amazon, could you confirm if it works with any isp? As that would mean misleading people about the router if not.

I was told that the 02, zen and talktalk versions of the TG582n are totally locked down. So that maybe why I can't flash it the normal way. He was not 100% but thinks that you can flash the plusnet router with other firmware.

How it works with the firmware and isp's. The isp's tell thompson what they want on their routers, how much they are locked down and anything else to do with them. Thompson then make the firmware and install the firmware, not the isp. They then make thousands of routers specific to the isp requirements and ship them to the isp's.

So as it's done all at the factory, it makes it harder for us to make the router do what we want it to do.

Was told that the reason isp's use the TG582n ADSL+2 router is because it's cheap. Thats why they won't use a proper VDSL2 modem/router, even though thompson sell them in the netherlands.

Their is always a way around things but hacking the router maybe the only way on certain brands. Since they changed to technicolor, they have got worse. I would avoid all new technicolor routers and this company in future. If you need a broadcom chip, other brands of routers, use them. Best to get one of them.

TFTP is a fall back situation that allows you to recover routers even when their firmware is corrupted, i.e. the code for this is running in a ROM so cannot get corrupted

Usually so long as physical hardware is good, you can play with TFTP and versions till your hearts content, at which point you've gone well beyond the cost/benefit game and are into the figures it out for sakes sake

Urm the reason providers in the UK don't use a proper VDSL2/modem/router is that Openreach insists on its modem. Wires only appearing in 2013 will change all that

Well it is rather silly having to have a separate modem and separate router. Would be better if they supplied a vdsl modem/router in the first place. No arguments then.

In reply to a post by superspeed:

Not really.

On the whole a modem is a modem is a modem, but I'll choose my own router thank you very much.

If it was a vertical operation it would, but to meet differing needs of people like Sky, TalkTalk and BT Retail a two box solution has been the way for a while.

When ADSL started it was the same, with some people evening needing three boxes

With openreach providing a modem that has the same interface for routers with both FTTC and FTTP it actually makes things easier overall.

The 585 Upgrade wizard finds my Plusnet 582n.

I have a tg582n_r8.4.4.J.bin file which I think is the firmware, and which I have not used.

My Plusnet 582n is running 8.4.4.I

(Letter I for ink not a 1)

Most of the upgrade wizards should be able to find the TG582n. Plusnet firmware will work fine on a plusnet router.

This is about flashing say, an 02 version of the same router with other firmware, say from plusnet.

Yes you can chose your own router but for a all in one solution, it's better to just have the combined router and modem. Then if you don't like that combined router/modem, you can use your own. A bit like how BE used to work.

I note what Mr saffron said as well though.

I opened up the Technicolour TG582n to take a look inside. I could not find a circuit board photo around the web so took my own. See links below.

Main http://s6.postimage.org/nv9xae5q9/72_echnicolor_TG58...
Back http://s6.postimage.org/janqvgm0x/image.png

I was looking round the board to see if I could find where the wireless is transmitted from. Well think I have found them. I have marked them out with arrow and box.

http://s6.postimage.org/bkgyqbjpd/72_echnicolor_TG58...

On other routers them copper points, are what connects to external aerials but this has none. Like here for example http://www.thinkbroadband.com/images/reviews/fritzbo...

So if that is where the wireless signal is coming from, no wonder the wireless on this router is so crud. External aerials are much better.

Plusnet supplied my 582n FOC, I would only be liable for the charge if I leave within a year of the date the router was supplied. I was not even asked to pay postage.

It looks like there are two possible versions of the 582n firmware on the Plusnet site.

I called a official reseller of Technicolour today and asked about the TG582n Router they were selling.

I asked if it was a generic version. Anyway called back later and was confirmed, it is a generic version, that will work with all isp's. They offer 1 year support with it as well.

They told me they also, flash generic versions with the isp firmware for isp's.

Thought you would like to know, if you want a generic version.
Here http://www.dslsource.co.uk/View/TECHNICOLOR-TG582

Also found this forum http://www.broadband-forum.org/ where isp's and other use it. Maybe it has firmware or something on the forum. It's not for the public though.

Due to the adverts problem on the images I am reposting what I posted before but as I can't remember half of it, it's not the same as before. Any bad adverts that show up on the links, let me know or over in TTTS. It's a problem with the image host.


This will be my last post on this. This is some photos of the plusnet version TG582n. Not a lot different compared with the o2 version. Only difference is the plusnet has winbond memory that�s not on the o2 version.

I bought and ADSL version that is for Plusnet but want to get it working on fibre. Plusnet told me the routers are all the same, just different firmware.

So if anybody knows or can link to the most up to date firmware for plusnet fibre, please post. Not demo versions or old versions.

The TG582n Routers I talk about won't work on any isp and unless somebody can hack it, then this router is just a worthless brick, if you leave your isp. If you can buy a so called generic version, like above, then you should be ok.

No, I rather have my own freedom router as mine is Netgear DGND3700 and this router is brilliant can connect via BT FTTC modem, BT ADSL2+ and Virgin Media Cable. I prefer seperator!

In reply to a post by Michael_Chare:

Do you mean you can change the IP address of the router itself?

I'm trying to change mine to 10.0.0.1 to match my network but I can't see where to do it.

[Edit] Thought I'd answer this myself.

To change the IP address of the Technicolor TG582n router via a web browser:-
Login on the old IP address
then click on
Home Network > Interfaces > LocalNetwork > Configure

It appears the router can have two LAN IP addresses.

I hope this is of help to someone.
