You may find the table below helpful. On a windows machine, check maximum packet size without fragmentation using     ping google.com -f -l xxxx       where xxxx is the packet size. Note, although I would expect to see the max packet size to be 1492, on my network it is less - 1430, ie more than vlan tagging, software and firmware upgrades appear to have reduced the MTU. It is also worth check what SNR the modem is set to and asking if this is reasonable to your installation. Similarly, ask if cabling work has change the distance to the exchange/exchange with device that controls SNR.

A number of the printer manufacturing companies have implemented when might be generically referred to as e-printing. Effectively, one creates an email and attaches the document to be printed to the email. The printer is assigned an email address, and on receipt of the email, the attachment is printed.   It works even when everybody concerned is non-technical.   ... View more

I live, and mostly shop, in UK/Europe. I can't think of a single premium retailer that would risk antagonising its customers by resorting to the kind of targeted direct marking described in the above post. People who spend thousands of £/€/$ on on normally inexpensive items do not want to nagged to spend more. Armani are not going to sell any more suits using this kind of marketing, nor are Ferragamo going to sell any more shoes, they have private showings in cities like Paris and Milan for promotional activities. E-commerce isn't going to put a glass of champagne at my side, which is what happens in this type of shop.   Sometime the nerds should be encouraged to go forth and multiply elsewhere. Whoever thought of using Walmart customer advertising in premium situations is short of a few marbles.   Although seeing as how so many of the "customers" have Italian origins, I'm not surprised, lovely though they are. I buy my hats from a distinguished Italian establishment, all their staff would rather die than indulge in such marketing techniques. ... View more

I wondered that, but on having a look Cloud4Wi is a WiFi location based analytics business, that seems to have developed in Italy.   From their web site -  Top global companies currently rely on Cloud4Wi. They include Adecco, Aldi, Armani, Bank of America, BAC Credomatic, Burger King, Campari, Carmila, Clarks, Drogasil, Estacio, Gruppo FS Italiane, Klepierre, Lacoste, Illy, MaxMara, Olive Garden, OVS, Prada Group, Salvatore Ferragamo, The Cordish Companies, and Valentino.   I see the reason for the op's question, - Meraki does location analytics, and so does Cloud4Wi in some quite significant businesses. ...

How long have organisations resisted upgrades to Win 10? Do they downgrade new laptops and workstations to Win 7 from Win 10? Chicken-Little springs to mind. Microsoft ends Windows 7 support: What should you do? The UK government has admitted that Win 7 is insecure (they allege the ransoming of National Health Service could not have happened if hospitals were running Win 10). Win 7 has been branded as unsafe for online use. So it is "OK" for hospitals? Duh, they live in an online world (well their clinical staff do, the administrators are another matter entirely). There are some interesting costs set out in the BBC article, Australians would be interested. ... View more

Seriously -    to quote another commentator -    Windows 7 is due to reach End Of Life (EOL) on 14 January 2020, but a large number of the world's computers, most in corporate environments, are still running the nine-year-old system. Microsoft ended mainstream support for Windows 7 in January 2015, with extended support running till 14 January 2020.   Do you really think anybody is going to give diddly squat about this, unless they are paid to do so? MS probably will cut a deal, because they have a track record in this sort of kr*p. ... View more

I know there is a modems compatibility document but as I need to buy one for testing, I would like to know one that is already tested for Mexico Any USB modem/router device must not only be compatible with the MX, but it must also be compatible with the MNO (or the MNO used by the respective vMNOs) in Mexico. I would first look at the web sites of the MNOs Telcel Movistar AT&T Mexico to see their various mobile modem/router/hotspot offerings. There are frequency differences between the operators. There are also 5G devices currently available. If you are an AT&T customer, you may have another option - to use the Meraki Cloud Managed Cellular Product.

I have checked the size and weight of the MG 21 (160.45 x 160.45 x 34.45mm and 497g). This set me thinking.   I think that I can stick a Velcro patch on the glass of a window and also on the back of the MG, to hold the MG firmly in place (worst case, Superglue the Velcro to the window, using Acetone as a solvent to remove it).    If I'm using a Z3C, it has an 802.3af 15.5W PoE port, and the MG21 draws 10 Watt Maximum also PoE 802.3af, whilst being a similar weight. So I could velcro the MG21 to the window and keep the Z3C on my desk. If only they would allow the Z3C or MG21 to access a WiFi network . . .  It would probably be easier to fit the MG21 into the computer bag than a roll of duct tape.   Now, all I need to do is get hold of a MG21 for testing  and proof of concept. ...

I've registered for the Node Red seminar on 14 January (hope I'm back from London in time).   Having spent a great chunk of my time in academia working on language design, I still shudder whenever presented with looking at anything written in Python. Honestly, it is as full of appalling error-inducing features as the original Fortran, that attracted attention thanks to a number of stellar programming misunderstandings so that their NASA missions were destined for failure.   Being able to use Node-Red with the Meraki API is a great alternative option. As a bonus, I have found that when communicating with engineering types, they readily understand what is going on.   https://developer.cisco.com/meraki/build/node-red-and-meraki-apis-demo/   It is worth giving it a go. ...

I have put Meraki kit on race boats. Basically the Meraki guff goes inside a water tight CFC case that has Fischer Connectors. Power is supplied via the Fischer Connector to internally mounted  DIN rail power supplies (and changed according to internal devices and external source 220/110 AC, 48 DC, 24 DC, 12 DC). External connectors include WIFi, Bluetooth, and LTE antennae, Ethernet(PoE option), CANBUS and some other stuff, including Siematic IoT2040(s) We have to get the CFC cases made, but our design office has the skills to make that in house (and the blokes like doing it). Most important, put an EPIRB-style device in the box in case you have to go fishing for it.   ... View more

You may find these helpful: In Which Geographical Region Is My Office 365 Tenant Hosted?  Where Your Data Is Located I omitted to add -  Office 365 IP Address and URL web service  This last document discusses a REST-based web service for accessing relevant addresses. But it doesn't disclose where they may be located. In the early days of Office 365, the location of one's data could be somewhat mobile, to say the least, to the point that for a time we could not sync certain categories of information with any of the MS sites, and had a separate secure data store in the land of the cuckoo clock. It is quite a good idea to store stuff in Switzerland, because the good Swiss burgers will promptly inform you if anybody gets an order/warrant authorising access to data. This makes them more inclined to 'fess up about potential breaches of security. Which isn't necessarily the same case in other countries generally regarded as well regulated and reliable. In no way, shape or form are mobile networks secure. Take appropriate measures (hint Moxie Marlinspike is your friend). Don't think fixed networks are any more secure. ... View more
