Unable to access NETGEAR WGR614v7 browser user interface after resetting

the fewer fancy "features" the smaller the attack surface is.
best to use open source firmware on it and keep up on any patches.

FOSS isn't a panacea as evidenced by the vulnerability in the HTTPd of his WGR614

One of the problems with FOSS is that folks don't think they need to understand the technology in order to benefit (in terms of savings in development costs) from using the existing codebase. That's why you see TV's (and other "smart" appliances) that crash -- cuz the code wasn't designed to run on an appliance! Or, in a potentially "hostile" environment.

[I.e., the folks using/deploying the code never take the time to read through it with an eye towards understanding its limitations and how it can fail]

Is it true that if I use an old router it will be less prone to hacking like my NETGEAR WGR614v7 router as I read somewhere that old computers and old computer hardware like floppy disks, routers etc. are less prone to hacking.

No. This is a misconception based on a lack of understanding of technology and how it can be (ab)used.

Once an exploit is known, it can be catalogued and then called up as needed and applied to whichever target is of interest. E.g., you can design a web site to look at the browser being used (not just rely on the information that the browser provides to identify itself -- cuz that can be spoofed) and deliver a customized page designed to confound that particular client at that particular time. Another client accessing the same page could receive a different payload tailored to his vulnerabilities.

Likewise, your host(s) can be probed to determine which services are running and those services probed to determine their vulnerabilities.

Even basic network traffic can reveal the identity of the OS that is behind it.

My "secure" laptop (e-commerce) is a stripped down system with no extraneous applications, no unnecessary services, etc. And, it has no persistent storage! Turn it off and the system forgets every exploit that may have been (successfully) targeted at it while it was running. Turn it back on and the effects of the exploit are gone, completely.

I.e., you use it for a specific purpose and then turn it off. You forego the convenience of checking your mail, opening PDF's, surfing the web, etc. in order to maximize its resilience.

Machines on which I want that sort of convenience trade it for a complete absence of any information/access that an attacker might want. So, if ever successfully breached, I am forced to reload all of those applications (from the disk image that I made when I built the machine -- a 15 minute recovery effort).

As a result, I don't have to stay current with the latest "security updates" from OS vendors. Nor perpetually update all of the applications I've installed. Nor worry about 0-day exploits! And, I don't take the performance hit of running (and keeping up-to-date) an AV/ID product.

[C'mon, computers are cheap enough that if you can't afford to have one for on-line use and one for REAL use, off-line, you're not trying very hard! ]

i also disable config via wifi.
this forces a wouldbe attacker to gain wired access to even try.

Hey I cannot watch everything ya know

I got Chemi-Cons KZM 470/6.3, even slightly better than FR. From the picture, you can also fit D8x12-15 cap bent 90°. Or put two 470uF in parallel, in the second vacant spot too.

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

btw, Bahamut could sell you cheap caps - i'm surprised he hasnt offered yet.

Thank's for personal messing me but are the capacitors offered of good quality.

[stj]

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

then it's a legit site

[Captain Bill grace digger]

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

try mouser.com and select your country.

That is exactly what I did.

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

no, i have no idea if mouser.in is legit.

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

"Thank's a million" but can you also please conform if this is the right part and a legit website to purchase. Link is below.

http://www.mouser.in/Search/m_Produc...S4JxBTbQFzM%3d

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

you can see the lead spacing on your board.
for a 6.3mm diameter cap it would be 2.5mm

the other question relates to how many you want to buy.

[Captain Bill grace digger]

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

Please check if this is the right part and also if the website is legit and safe to purchase..

The link of the website with part discription is here - http://www.mouser.in/Search/m_Produc...S4JxBTbQFzM%3d

Can you please also specify the

• lead spacing wheter - 2.5mm or 5mm and

• Packaging wheter - bulk, cut tape or reel.

as the website is asking me to choose them in the filter section.

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

then you need EEUFR0J471
or something from nichicon/rubycon/ncc
but i dont have the datasheets for those in front of me.

[Captain Bill grace digger]

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

The old cap is 6mm wide and 11mm high.

[stj]

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

no, VZ is not suitable AFAIK.
btw, that website is a joke, it must be run by a monkey.
every time you click on anything, it reports it to FaceBook!!
it does all kinds of stuff in the background!

you never did say how wide the old cap is.
if it's 8mm then maybe this:
https://www.tanotis.com/products/pan...al-leaded-8-mm

i dont trust the seller not to be selling fakes though.

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

what is the diameter of that cap?
the replacement must be the same size.

I guess the capacitor in the link below should be just the right fit. It looks exactly the same diameter when I measured the cap on the PCB with a measure tape, It also is 470uf and 6.3v and it is from Nichicon PLEASE just have a look.

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

capxon fail very quickly,

what is the diameter of that cap?
the replacement must be the same size.

i would use panasonic FR series, but maybe you cant get those.

[Captain Bill grace digger]

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

the replacement must be low impedance type btw.

Which type of capacitor should I exactly replace it with.

It says it is a 6.3v, 470uf capacitor. Is there anything else I should look for.

[Captain Bill grace digger]

Re: Unable to access NETGEAR WGR614v7 browser user interface after resetting

the top should be perfectly flat.
if it's sticking up then the liquid inside has boiled.
also, if you see yellow or brown on the top then it has leaked.
also it's made by CapXon.

WOW! I took a closer look at the PCB again and saw the green cap's top is really swelled and it also has a brown dot on the top.

But what is wrong if the capacitors are from CapXon.
