    Netgear WGR614V6

    This router was working fine, then suddenly lost it's mind. Page timeouts and finally one crash.

    Seemed to get slower and slower loading pages. No obvious heat damage.
    Replaced with a Linksys, problems went away.

    Two caps are CapXcon 470uf 6.3V & 220uf 25V. Look ok at ESR within reason, though not low-ESR.

    These things have ram & a CPU apparently. Firmware was up-to-date from Netgear.

    Can anything obvious be done, or just scrap it?

    I would ensure that the PSU is OK. I have worked on a lot of routers and have only seen a few with bad caps. Recently in my own home i had a router causing havoc on our ADSL line. Symptoms were re-boots and lowsy browsing. Even though the PSU seemed ok it was creating noise on the line. I re-capped the smoothing capacitor within 12V psu which rectified the problem. The PSU on mine was the brick type. They are quite cheap to buy. I just like to carry out my own repairs first. Normally a challenge, and you get satisfaction if it works.

      Those one chip PWM buck regulators seem quite tolerant of large changes in capacitance. I'd tack on a 2200uf capacitor at the blank spot C114 and see if that straightens it out. Then you know that the green CapXon has failed or the bean counters cut one too many capacitors. Increasing capacitance and using better than original parts can change these routers from occasional crash to super reliable.

      U13 and U4 may be linear regulators but I don't see the output capacitors that regulators normally have.

      RAM can fail too but that may be beyond your ability to replace.

        I saw a (working) linksys with a bulgy cap inside

          A lot of the new units have a lightweight external power supply, which means it is a switching unit. They are quite hard to open and there is no easy way of know what is inside it.
          My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

            How did you open up the brick? Mine is quite heavy and has no screws visible, maybe under the label? This one is 12v 1A.

              pry them apart at the seam. it may require a hacksaw, a hammer, and flathead screwdirver

                Glued cases can be split fairly cleanly with a bench vice. Lightly tighten the vice on one half of the case to apply tension to the glued joint. A hammer and screwdriver will split away the other half of the case.

                I use a zip tie to put it back together.

                  Thats exactly what i do. I also use glue to seal them back up gain

                    I have exact same router, which is still working, but it had this crazy high pitch noise, occasionally, it would drop lot of packages, it seems freeze up loading pages. It was impossible to play game with it.

                    CapXcon 470uf 6.3V is Low ESR, I replaced it with a better brand 1000uf 6.3V capacitor with exact same diameter, slightly taller than it. I also add extra 1000uf 6.3V capacitor at C114.

                    220uf 25V regular capacitor, I replaced it with 1000uf 25V Low ESR.

                    To me, these capacitors are purposely over worked, it is design flaw. Now, it works smoothly without any noise.

                      same issue, my wrt614v5 case is discoloured, which is caused by the heat and also found out that it is having a high pitch, coming out from teapo caps, no bloats. Eventually replaced with a panasonic FC type, the high pitch is gone and relative stable, less heat.

                        all of my netgear routers wireless and vpn have quit working properly. I have 2 of each plus an old print server and some othe type that I could never get to load a page other than the netgear configuration pages. I thougfht that they was incompatible with IE8 or Win 7 and replaced them with a Linksys wireless and no issues at all! I did this about 6 months ago, and I've noticed a huge number of netgear routers appearing a thrift stores. I made my conclusion that this is a compatibility issue based on that.

                          Just chiming in because I just fixed a Netgear router (WGR824 v2, IIRC) that had siilar symptoms to the OP's. As some have suggested, it did turn out to be the wall wart. Check the voltage with a multimeter, the voltage on mine was very low. Turned out to be a visibly bulged cap on the output, after replacing it the router has been working fine for about a week now.
