tp-link router died
 
Dont't buy a tp-link ADSL wireless router ! Mine only lasted just over a year. It was working but I could not access its http console (visitor wanted the pass phrase), so I restarted it (power cycled). After that it acted as an ethernet switch but nothing else. It was as if the control part of the device had failed.
It would not even respond to the reset button, so no return to factory presets possible.
Replaced with a netgear one - the previous netgear router I had lasted years.
I know none of these are high end devices, but they should do the job.
DIY ? Well I bought it myself and plugged it in myself ;-)

Thanks, but I don't think a sample size of 1 as going to influence me
one way or the other.

Apart from that, you havn't given us the model number.

Oh I didn't think I'd bother. I didn't think a sample size of 1 was going to influence you one way or the other. Don't you recognize and excuse to vent ? (model TD-W8961ND Ver 3.0 S/N 12986703642).
A sample size of 1 may be statistically insignificant, but there is a significant chance that if something happens, it happens more than once (because its due to an underlying design factor). Or is it because I split my coffee in it ?

My TP Link router replaced my Belkin router which died earlier this
year but as each of them only cost about a tenner I tend to think of
them as consumables like paper and ink. I could buy a really nice
router for Belkin/TP price x n where n is a big number but I'm not
convinced a nice router would stay alive n-times longer than my
cheapies or even that computers will still use the same standards in
n-times years time.

I used the same logic when buying wrist watches, preferring

replace it. Now I don't even use one.

That's the reason the previous ones have been
replaced, first to get wifi and then to get ADSL2+

Not that the current one cost much, got it at a garage/yard
sale for peanuts because it has full voip support too.

I don't either anymore, but with stuff like routers
and smartphones I want something that performs
a lot better than the lowest cost **** does.

And absolutely classic example of that is the lowest
cost android smartphones that have so little memory
that you can install **** all apps on them. What is the
point of farting around like that when paying a bit
more for a phone with a decent amount of memory
avoids all that farting around entirely ?

I've given up with my TP-Link WR1043D after about 18 months - it falls over if it gets slightly too warm and has a number of irritating minor bugs, for example some, but not all, internet radio station start buffering after half an hour or so. I assumed it was issues with the streams, but having switched back to my bombproof old Netgear DG834G, that streams all stations fine and doesn't fall over if the ambient temperature reaches 25C or whatever. The TP-Link was very cheap for the functionality but looks like for once I got what I paid for.

I suppose as this is Uk d-I-y I ought to flash the TP-link with DD-WRT or somesuch third party firmware but frankly I don't have that much time to waste.

2 years ish...

Mine did have a bug where it would drop the wireless connection.
However, I saw a beta firmware release mentioning it had fixed this
(before I'd fully realised - I thought it was my laptop being silly) and
it's been fine ever since.

Personally I'm quite impressed with the feature set on mine.

Yup had a bunch of D-Link switches fail for just that reason (internal
PSU rather than soap on a rope, but same principle and fix).

Probably had half a dozen TP-Link switches in the field now for a few
years - not had any failures.

That's a bit of a sweeping statement. It's surprising just how
different they can be. However, you do see badge engineered versions
of Zyxel(?) and Netgear kit re-marketed by the likes of Peak and
(spit!) Belkin.

If I had to make do with a badge engineered version, I'd choose Peak
over Belkin every time. The hardware might be the same but the OEM
customer (Belkin) will usually employ someone to write, in Belkin's
case, a ****e version of the firmware so full of security lapses as to
turn a moderately bad piece of kit into a festering PoS so bad that
anyone with a moderate level of knowledge wouldn't want to touch it
with a bargepole.

If there's a DD-WRT firmware available for that model, I'd be taking
it apart to replace any suspect caps and enlarge any existing vent
slots and adding a couple of square inches worth of ventillation holes
in the base of the case (7 to 10 mm drill bit sized) and, if
necessary, drill a few in the top of the case to supplement the
existing vent slots if the effective CSA can't be increased to match
the holes in the base[1]. _THEN_ and only then, would I deem it worthy
of such a firmware upgrade.

That's actually an excellent observation. That could well be the root
of Simon's problems with the TP-Link.

However, since the use of switching regulators in these cheap
commodity routers and switches has displaced those ancient analogue
voltage regulators for well over a decade now (purely on cost cutting
grounds), it's a simple enough problem to fix since the only matching
requirement of a substitute wallwart is plug size and VA rating over a
voltage ranging from a low of 6 to a max of 15 volts DC.

The switching regulator will (unlike the specials used in laptop
power management switching regulators) cheerfully accept a wide range
of input voltages equal to or greater than the output voltage

it's a ba-na-na . . . .


Thanks for the tip, might try running it off a proper stabilised PSU for a week then and see what happens.


If you've got a variable voltage bench psu to hand, you can start off
at the 'rated' input voltage and slowly wind it down, observing the
current draw. It's extremely unlikely that you won't observe the
negative slope in the volt/current plot that's characteristic of a
switching regulator.

If you observe this, you can then increase the voltage above the
'rated' voltage, perhaps limiting it to a max of 15 volts just to
remain on the safe side of the input cap's voltage rating.

Once you've ascertained the use of a switching regulator by the
wallwart powered router or switch, you'll know for sure that it's safe
to make use of almost any old wallwart with a sufficient VA rating as
a replacement for the originaly supplied wallwart.

The only remaining issue being the question of the DC lead's jack
plug size. IME, such jack plug issues don't occur all that often since
there seems to be a singular size favoured by the makers of such kit
(unlike the laptop makers who deem out of warrantyreplacement mains
charging bricks to be their version of inkjet refills).

If there's a DD-WRT firmware available for that model, I'd be taking

necessary, drill a few in the top of the case to supplement the
existing vent slots if the effective CSA can't be increased to match

In case its any use, some info on DIY cap replacement etc:

I try to mount my modem/routers, switches, access points and VOIP stuff
vertically on wall mounted boards as I reckon the cooling will be better
that way. We've not got enough to make rack mounting worthwhile.

Side benefits are they don't get kicked about and I don't have to bend
down so far to work on them :-)

True enough, he was opining that _most_ of this kit was a matter of

opinion that's just as far off the mark as your claim to the contrary.

That's actually an excellent observation. That could well be the root

of Simon's problems with the TP-Link.



However, since the use of switching regulators in these cheap

commodity routers and switches has displaced those ancient analogue

voltage regulators for well over a decade now (purely on cost cutting

grounds), it's a simple enough problem to fix since the only matching

requirement of a substitute wallwart is plug size and VA rating over a

voltage ranging from a low of 6 to a max of 15 volts DC.



The switching regulator will (unlike the specials used in laptop

power management switching regulators) cheerfully accept a wide range

of input voltages equal to or greater than the output voltage

threshold (typically 5 volt) that's within the upper input voltage

limit, usually defined by the input capacitor voltage rating

(conservatively, a maximum of 15 volts).



You can safely power 99% of all such kit from any 10VA rated

nominally 12 volt wallwart that happens to have a suitably matched

plug on the end of its DC output lead (if necessary, you could always

use the plug off the old wallwart to fix this issue if needs must).

Maybe I shouldn't throw it away then, however I suspect it would go into that box of things that I really should throw away, to be fixed one day. If I manage to keep stuff long enough I could fix them in my retirement, but I'm sure the stuff would be obsolete by then.
