    Wide open?

    The local cable monopoly Rogers uses crappy* cisco routers that provide both a secure(ish) and a wide open guest network that requires you to open a browser and enter a password to get any place. Of course that makes your traffic open to sniffing too.

    *The two people I know that have them have to reboot them a few times a week.

      Re: Wide open?

      The open guest network is not that bad. Presumably the owner would not be using the guest network, because that's tedious. And guests aren't normally an everyday occurrence. You'd pretty much have to lie in wait, biding your time, until a guest comes and enters the password. If it's traffic you want, it's much more efficient to go to the nearest coffee shop.

      Much more fun are the crappy Cisco routers where the supposedly "secure" network is vulnerable to the Reaver attack.

      Re: Wide open?

      I know those modems. The guest network is fine and not actually open. A lot of hotspots appear open but use other authentication these days so WarKitteh is likely to be deceptive in stats. Generally Wi-Fi is reasonably likely to be secure when I've looked around lately, we're far from the heyday of wardriving. Usually if you want to crack a network Reaver is your only option, and most WPS schemes have protection built in against it now anyway.

      An aside, those modems aren't Cisco. Most Rogers hardware is from Hitron. The current "state of the art" modem they're pushing everyone to is a Hitron CGN3.

    The BT Home Hub 3 I am lumbered with reboots itself "randomly" or drops the ADSL connection before re-establishing it at a lower speed on a daily basis (only occasional periods of 4 day connectivity). It's really bloody annoying when halfway through a secure transaction. Strangely started to happen after BT pushed the new firmware onto it back in March and that was done while I was busy.

      Since you're feeling lumbered, I feel I should point out you can use your own router (depending on what services you use from BT). Just put the username on a 3rd party router as, leave the password blank.

      I'm lumbered with a BT Internet connection, but I refuse to be lumbered with their "I'll resell the pipes you're paying for to BTFon users" router.

      Re: "reboot them a few times a week" - Luxury, sheer luxury

      Not the first time BT's firmware wizards have buggered up firmware, there was a longstanding issue on one of the two revisions of the Home Hub 2 where an upload of more than a specific not-very-large-amount-of-data (of the order of a few MB, IIRC) would cause the damn thing to reboot. I ended up with 3 of the things, because they screwed up the first replacement and gave me a second buggered unit. (Details at, if you're interested).

      If it's happening regularly, get onto their support folks. They probably won't want to, but stick to the "your product is stopping me using the service I pay for" line and they should eventually give in...

    Wifi Open at the in-laws

    Even while sitting 3-4 meters away, the signal was so crap, I was loosing connection every 10 minutes or so. So I doubt there is anyone outside the house, and outside the perimeter fence that can even tell there is an AP in use. If they could see the AP, I doubt the return signal would be received by the AP. It's a big old house.

    Curious though, lots of the neighbors cats frequent the yard!

    not even more cat videos filling up the interwebs!

    Cats are not my friends at the moment. One has taken a fancy to sitting on the petrol tank of my Motorcycle in the sun. Said tank is black so it gets very warm. Apart from the scratches, the beast has decided to mark the bike as hers. Cat spray stinks to high heaven.

    Even pressure washing the bike fails to remove all the traces of the smell.

    Perhaps the 'collar' could be be modded to strangle the wearer if they go to certain GPS locations?

    Before the cat lovers get angry I've done nothing to the cat.

    The 'owner' just laughed. Perhaps I should spray her (the owner) instead of the cat?

      Re: Noooooooooooooooooooooooo

      For some kitties, you can mix water and vinegar in a bottle and squirt it on them. Be sure to squirt a place they can lick, otherwise you'll be smelling vinegar for a while. Once you squirt the cat, he will spend a few moments cleaning the vinegar off his fur. For some cats, a few squirts of this and they will learn.

      But some cats don't respond to this. What worked for me was one of those devices that emit a high-pitched noise that hurts a dog's ears. Well, it hurts a cat's ears too. If the cat isn't deaf (older cats tend to go deaf) then a couple of quick zaps with these devices will do the trick. If this isn't your cat, you will want to try this first, because your neighbor might smell vinegar squirted on a cat.

      Just bill the owner for repairs. Their animal, their responsibility.

      If they refuse to pay up they can look forward to paying for repairs plus your fees in the small claims court.

        @Fibbles Re: Noooooooooooooooooooooooo

        There are no remedies in law holding the owner of a cat responsible for the actions of their pet. Cats are exempt from the laws governing animal trespass. They can also look at the king.

        Speaking as the owner of two cats, your best solution is a good soaking with a hose. One of those spray fittings works best.

        I'd also suggest putting a cover on the bike. It's a reasonable thing to do anyway. Keeps the bird shit off.

      If 'she' is spraying your bike 'she' is almost certainly He, most females don't spray.

      Just to eliminate one potential cure to stop cats spraying your bike or anything else; A friend of mine in the UK wanted to stop a local tomcat from digging up his bedding plants and replacing them with lovingly crafted cat turds, while shopping to replace lost plants in the local garden centre he discovered pellets that were derived from or contained tiger shit. The idea obviously being that a tiger is somewhat further up the ladder of catkind than a local moggy, the said moggy however had clearly not been watching the Nature Channel and had no idea what had produced the new smell on HIS gardens so he sprayed and replaced bedding plants even more.

      Or maybe he had been watching and knew there were no tigers in South East London.

        Not being a cat owner, I don't know if is it spray or pee. All I know is that is smells somthing rotten.

        The tiger poo derrived pellets look rather interesting.

        Taking the owner to court is problematic. They are the owners of the freehold of my home. I'm the leaseholder. I think the deterrent method is the way forward.

      The best way to remove cat spray is to use biological detergent in the cleaning water. Cleaning the patch not the kitty, obviously. Cat lover who resents tom cats marking their territory near the house.

    Cats and the Interwebs...

    The first mistake was teaching them to use a camcorder to make the vids.

    The second mistake was teaching them to use a browser so they can upload the vids.

    Now we're seeing the third mistake... we're teaching them to seek out un-locked down WiFi units.

    In a few months, they'll own 90% of the Interwebs and Google won't return any useful human links only cat links.

    We're doomed I tell you!!! Doomed!!!!

    AC motorbike: perhaps if you precariously set a trayful of clattery things (pot lids, tin cans) on the seat and tank of the bike, the monster will upset them when she/he/it jumps on the bike and might get enough of the bejabbers scared out of it that the problem is solved. Not the most aesthetically appealing solution, but one of the more humane ones. Good luck!

    How many of those networks not using Wifi encryption were unintentionally, or through lack of awareness, doing so? E.g., how many were not FON-type shares, or local businesses having a guest network intentionally open (whether secured with a captive portal or not)?

    "Some unconfirmed estimates suggest cat-related content consumes as much as 15 per cent of internet traffic"

    I think that the wildly different content sought by searches for "Cat" and "Pussy" may be skewing the stats.

      "I think that the wildly different content sought by searches for "Cat" and "Pussy" may be skewing the stats."

      That may be true, but search engine analytics would be able to differentiate between searches for "pussy" by detecting whether the search is run with the family-friendly filter on or off...

    This situation is madness. Equipment vendors simply need to make WPA2 security the default on any home kit. Modern kit (iX, windows, whatever) is all trivial to set up so there is no excuse. It's about time we stopped trying to make the in- interested consumer try and work this stuff out. It's bad enough trying to get large enterprise to spend the time/money doing Wi-Fi properly let alone my gran.

      Re: Madness

      Well, I set up my wifi with a guest account on open wifi a bunch of times when I had a party on, or when neighbours moved in/out and needed temporary access, just to have the average Joe/Jane not nagging me for passwords. I know. Lazy. I frankly don't care in those situations they are open to packet capturing, as I'm not their brother's keeper. Just don't do your banking on it if you are paranoid.

      My own WPA2 secured wifi also is set up for MAC filtering. So only "authorised" users can get on it. Unless of course a real savvy user comes along and breaks through the defenses, but then what chance would I have anyways? The MAC filtering was a remnant from when I had to use open wifi as some peripherals didn't play well with wep/wap (stupid printer, and a security camera (really!!) ).

      And cats are vermin, not cute and not funny, and think they are the boss. Like real bosses really.

    What keeps cats away.....

    They don't like the smell of citrus- lemons and limes etc. So after you've finished your G&T take the lime or lemon slice and put it on the tank. They really don't like the smell. I haven't got a motorbike to protect but I leave the slices on the garden to stop the bastards shitting there ( why don't they seem to bury it these days?) and also around a small bush which they like to mark
