I make good use of old(er) routers with the 3rd party RouterTech firmware. One of these is refusing to recognise 100base-t ethernet but is happy at 10base-t speeds. I've seen on the web a similar model of d-link and some other brands where this problem has been fixed by replacing some of the caps.
I found one thread here on BadCaps that mentioned the G604T but no feedback about if the recap worked.
Examination of the router reveals the majority of the Electrolytics are GSC and the rest are TBOR (if I read the logo correctly).
There are:
GSC 1000uF 35V x2 - main PSU caps + space for 2 more.
TBOR 225uF 35V x1
TBOR 220uF 16V x5
GSC 100uF 16V x8
GSC 47uF 25V x4
None show any obvious damage.
Supply is 12V AC 1.2A (ie. unregulated). So I think those capacitor voltages are all pretty nominal.
Some Questions:
Has anyone recaped a G604T?
Is it worth giving it a go given the brands involved?
Is it better to work in sections, testing as I go?
Or just do all of them?
I'm assuming an old Oryx-50 iron should be able to pump out enough heat with the aid of some desoldering braid or a cheap sucker?
Aside:
One thing I have learn while researching this is that many (most?) smaller capacitors like those above are only rated for 1000 hours at full load. And that was Panasonic FC. In a router left on 24/7 that's only 41 days. Even if we assume they'll last rather longer at more moderate voltages, temperatures, & fluctuations you need a factor of 9 to last a year. These routers were made from about Nov-2003 so some of them need need x53 for 6 years. So to some extent failure can't be surprising, even if its breakdown rather than leakage or blowing.
