    Which Router for small business

    That is generally how every serious vendor works though - the trade-off is you get issues fixed promptly and up to date firmware for the life of the product. Ongoing software dev isn't free...it's also, as pointed out, really very cheap for a low end SRX...

    is it really "illegal" to set your wifi channel range to a non UK range?

    Would you like to reflect briefly on how utterly unfeasible that is in the real world? I mean, seriously, it'd be lovely if everything in the world was only done by professionals but that's never going to happen and of all those things - this is right near the bottom of the list. The defaults...

    Apple losing its edge?

    Sure it can be done on your phone, but everything that you can do on your phone can also be done on a laptop, it's about convenience. Sure, you may not value that convenience but doesn't mean others don't and at £35 for an Echo Dot recently, it's a trivial purchase with no ongoing costs...

    *** The official Apple Watch Strap/Band Thread ***

    I picked up the Nomad 'Modern' strap in brown leather recently and I'm extremely pleased with it, it's not cheap ($60US) but it's on par with the apple leather straps quality wise in my view and I'm expecting it to age well. Would recommend to anybody prepared to spend the cash, may well grab a...

    *** Official Hyperoptic Discussion Thread ***

    The usual setup is a single 1Gig point to point from the usual suspects (Openreach or VM Business), their peering setup as publically acknoledged is at https://www.peeringdb.com/net/4507 which is reasonable in my view for an ISP of their size, their transit I don't know how much they have (I'd...

    *** Official Hyperoptic Discussion Thread ***

    I've been told the roll-out is in progress (good news!) but they seem reluctant to find out when my building might be done (having been responsible for the roll out IPv6 to 300+ POPs in about 5 weeks several years ago, this whole story disappoints me). I'm hoping for proper IPv6 PD with a /56...

    *** Official Hyperoptic Discussion Thread ***

    I don't suppose anybody has yet had IPv6 activated by Hyperoptic for their connection and received any details on the configuration (ie. Prefix delegation etc) - they seem completely incapable of or unwilling to tell me much...

    Conectivity problem ISP cant solve

    This is potentially a semi-known problem with the network where the network thinks you've disconnected and your router thinks you're still connected. Your issue will be getting Talk talk (or any consumer ISP) to recognise that this is a genuine issue rather than user error. I don't really have...

    Buying a UPS

    It's worth noting, the average length of a power cut in the UK (OK, actually in the area covered by UK power networks) has been hovering around 40 minutes for most of the decade. I've been meaning to try and get some data on the 95th percentile outage time from them but it's broadly safe to...

    Spec me a wirless/Bluetooth mouse for my MBP?

    For what it's worth, I have both Magic Mouse/trackpad and a Logitech MX Anywhere (primarily for another laptop but having three 'connections' on it is super useful). On my MacBook Pro at my desk I end up using a combination of the trackpad and Magic Mouse for work and the MX Anywhere if I want...

    That might work, unless they used a sequence of really small packets - if they used packets in the 30-40 byte range you're hardly going to kill the performance of your connection by setting the MTU to 20 bytes are you (or maybe you are, but it's a poorly thought out response). Another amusing...

    Well, I haven't run the numbers but I think even then, because the padding is somewhat predictable, you could use a similar pattern and statistical analysis to get to a fair degree of certainty... This is all academic really, this is merely about what's technically possible, it's not actually...

    Recommend a Gin

    My Gin collection is currently: - Botanist - Sipsmith VJOP - Aviation - Various Inverroche varieties Just finished a bottle of Tarquin the other day. Would recommend them all. If I'm travelling/ in hotels etc without a great variety I usually stick with Hendrix...

    This is partially true (it depends on the encryption algorithm and implementation) but isn't always true in modern encryption. But the padding in the cases where it is used it always pads to the next multiple. This is the obvious implementation as padding to anything else would be a slightly...

    Oh, it'd easily be enough to justify a warrant. It might be enough to bring a civil case against you, where (see my previous link) they, in layman's terms, basically only need to prove that their version of events is more likely to be true than yours. As said earlier though, there is a...

    TV Licence Wi-Fi detector vans

    No, because encapsulation is predictable, if I encrypt a packet with simple GRE for instance then I know it's an additional 4 bytes on the packet. So to remove the encapsulation I remove the 4 bytes which are in a predictable place. If you want to pad the packet to a certain size you need to...

    No, it'd hit performance hard because you'd have to interact with every packet, work out what was padding and what was original content and then modify it back at the receiving end. That's untenable at any scale at all. It'd also introduce some latency and potentially some jitter, which isn't...

    TV Licence Wi-Fi detector vans

    It's not destination here that's in question, simply size, and size is nothing to do with WPA or wireless generally, it's determined by the packet the application and network stack on the host create... Taking apart packets to normalise size would be prohibitively expensive in compute terms...

    TV Licence Wi-Fi detector vans

    They're not a fixed length, that's basically impossible, applications will generate different length packets and a VPN basically has to pass them on, you could pad them to a fixed length but you'd have to un-pad them somewhere otherwise they'd make no sense to whatever you're sending them to...

    Doesn't need to be wifi on the machine in theory, just on the same network, if you have a wired machine plugged into a BT / VM / virtually any normal home router then it can potentially leak the traffic. That's an extreme case of course, I think they'd be satisfied with catching the wifi users...
