They may have done in the past if they used Chinese electrolytic capacitors, renowned in the trade for only lasting a short while. They left out the trace elements used to slow down electrolyte decomposition that the Japanese manufacturers have always used. I think they've sorted this out now though. Failed capacitors go leaky and low in capacitance, cause noise and instability problems, so an ADSL slowdown wouldn't be that unlikely.

Now funny you should mention netgear..but I have had a few run ins with their stuff..not overly impressed shall we say.two cans, some string and some BLOWN CAPS:I was only talking about routers that sometimes work. Netgear is
essentially two tin cans and a string.
just went thru the cap replacement a few days ago. don't mention
netgear to me - grrrr!!!

funny how netgear (old wellfleet) and linksys (new cisco) are the names people think of most often 
I wonder if any of their higher end (enterprise) class gear got these bad caps, at all?
boards may fail and customers won't even notice the blown caps - they'll just call field service and have a new board shipped out. but it could mean loss of network connectivity as these things fail in the coming years.
you know, if this was a US company who made these caps and caused all this trouble, they'd have been sued out of existance by now. but how do you sue a chinese company? answer: you can't - they are beyond our laws.
have we learned anything? no, I don't think the west has learned a single lesson from this ;(

Wow those caps are rated at 6.3v. Not surprised they failed, not a lot of leeway there.
The replacements look a lot heftier, although myself i'd be inclined to hang the expense and use Tants. They would handle the heat given off by that sink situated close by a lot better.
They also come in smaller encapsulations too, plus they don't leak and don't dry out.
Of course they cost more which is why manufacturers of relatively inexpensive items like routers don't use them......pity.

my thinking EXACTLY. sheesh! I design my stuff for 2x the voltage. why not! maaaaan....
the art of overdesign is lost on kids today, I tell ya.
a friend told me to use low ESR caps. I have none. I might get some, though. tantalums, though - for power supply filtering?? really?
by the time those big cans dry out, I'll be ready to retire (LOL).
I still have some old electronics from the 1950's and 60's. they still work, too. old VTVM meters and scopes and such. yet we can't, in the modern world, make stuff that lasts even 5 years (I know I'm exagerating but still ...)
I'm not happy about this 'cheaping out' trends in manufacturing. not happy at all.

Hi Bryan..
He's right, low ESR even better suited (forgot about ripple).
All those i've seen have been surface mount with short leads but i'm out of touch these days, guess you can get em with longer leads though.
Still as you say, those cans you put in look well up to the job anyway.
Old stuff ? yeah i love it. Used to have an old sig generator that ran on valves, or tubes as you would call them.
It was a huge thing, grey steel case with a gigantic dial on the front, scary looking.
I could fire that old thing up, stick a length of wire in the back and when i turned that dial knock out every tv and radio for a quarter mile around (chuckle !)
Happy days ;-)
