These are the more technical answers - at least some of many:



Or perhaps (I suggest) a more practical and simpler explanation...

A router is "box" which routes or links devices to each other over a network. Routers can know the address of each device to which it can link and when a message comes into the router it sends it the correct recipient. Routers can be programmed - i.e. locked down - to serve only specific addresses; or they can be in effect open to all... In the latter mode they are in effect simple automated post offices; they merely pass on whatever comes in to wherever. In the former they check what is incoming and if it's OK to do so then will send it on to wherever... Routers have associated software installed within them and this allows control of what the router can do; who can use it to connect who/whatever to who/whatever...

A hub on the other hand is simply a very dumb inter-conect box; it simply links anything plugged into it to every things else and has no control over what comes/goes through it...

Generally .. a router as applied to using one to provide an internet service around your home/office (the actual service being from an Internet Service Provider - ISP) contains both a modem and a router. The modem provides an internet service to the router... The router part usually has two aspects or facilities (amongst others). One is to provide a network connection using an ethernet cables between the router and assorted computers/printers etc.; and the other (and this applies to most routers used to day - but not all) also include a wifi facility and this when enabled is usually referred to as an access point.

Externally - when trotting about town or wherever you will find "access points" available from various sources; shopping centres/mall, coffee stores, restaurants, stations and so on. These are wifi services being made available to whomever - again from a router.

With wifi there is an added level of security (preferred) - as an access point is actually (generally) visible to all who are within range. Consequently one has to ensure only authorised users can "access" it...; hence the need to know both the access point's SSID (its name being broadcast...) and its security key - access key (frequently miscalled its password). That combination restricts who can connect and use it the wifi service (access point) and thus who can use the network of which it forms a part.

An ISP provided router usually arrives preprogrammed with all necessary info to allow it be more simply plugged in/powered up, and used immediately. A shop bought one requires a little bit of input from the end-user; and that's relatively easy to provide... Usually all that's required is the ISP account logon details and possibly one or two snippets of personal/local info...

If you're buying your own router - and many of us do - even though we may have an ISP provided one initially but prefer to use our own regardless, go for a typical router which includes the wifi facility. As I suggest earlier not all of them do. Also get one that has at least 4 ethernet ports; some of them may not...

Not sure why you mentioned hubs trvlr. As far as I know, nobody even manufactures them any more.........lol

The simple explanation is this:

Router: Connects to the internet and allows multiple devices to connect to the internet through it using wired, or wireless connections.

Access Point: connects to a router and allows multiple wireless (only) clients to connect to the internet. This device cannot connect to the internet by itself.

When to get which.........you need the router initially to connect your home/business to the internet. You would buy an access point if your wireless coverage isn't good enough and you wish to improve/extend it.

Breaking it down even further:
A Wifi router has a Wireless Access point built in. Some routers do not.
An AP or Access point or more correctly a Wireless Access Point allows wireless access to the network when connected to the network that is managed by the router. You may use an AP with a Wifi router if there is incomplete coverage or you can turn off any internal Wifi and use one or more AP's to form the wireless aspect of the network. Enterprise level AP's work together to form a complete Wifi network.

You have to be a little bit crazy to keep you from going insane.

I mentioned (included) a hub in my comments for completeness... True they aren't much used nowadays, but doubtless there are more than few still in use; and they're still on sale.

First, I just checked quickly online. I searched "network hub" and checked a few electronics sites. In every case, the links lead to switches. I saw no hubs for sale. If you know of one, send me the link. I'm curious to see who's selling them and also, who's building them. Just for my own curiosity.

Second, why mention technology as outdated as a hub? That's like recommending a rotary phone to someone looking to buy a smart phone. LOL

I still remember when we only had one phone in our house that hung on the wall in the kitchen....yes it was rotary. I remember our first touch tone in the 70's..........that was cool tech in it's day!

mmm fair comment Curt.. but one never knows... someone might wonder about "ethernet hubs" in the distant future and find their way here and discover they existed way back when; and were more commonly used than nowadays?

It's been a while since I went looking for a dumb device - aka a hub... You're right of course...; all that's out there now are now are switches...

Guess I have a couple of museum pieces - possibly they will become sought after relics of a bygone ages - and then I can sell them for humungous amounts of money and retire?

I'm open to offers starting at say ????

Ah rotary phones... Odd that people still want phones with the look (at least a simulation of the style) even though they're now tone operated... I used to have very olde phone which had the separate earpiece and you spoke into the "horn' style mic mounted on the on the wooden box hanging on the wall... Lost it on my travels... Those items are now worth a few pennies to some collectors; especially if totally unmodified/updated.

You're not the only one with a museum piece trvlr LOL

I have an 8 port hub buried somewhere in a box in the back of my closet. I bought it used from a friend around 1995/96 and it probably still works. I haven't used it since around 2001. In the logical progression of technology, hubs were doomed anyhow. Even a basic switch intelligently routes traffic only to it's destination ports, whereas hubs transmitted to all ports and in today's world and that's real outdated and why nobody makes them anymore.

We used to have a phone like you describe but it wasn't an antique. It was a touch tone phone with a fake dial (it didn't turn) We kept it so we would have an analog phone in case we lost power in the house and the cordless ones wouldn't work. Like so many others a few years back we got rid of the land line since the wife and I both have cell phones.

The problem with having no landline is that if the cell phone system (coverage, service) fails, for whatever reason, then one has no phone at home... Equally if one has a landline, but no standard corded (plug in) style, and only a cordless style, then in event of a power failure again one has no active phone at home.

Phone companies are required in the UK, Canada, and USA - at least - to maintain a landline system even if there is a power outage... The companies provide the volts required on a landlne from an independant supply/generator... I’m not sure just now how long that service is required (by law) or able to stay up; but Ithink it’s several days.

Friends in Vegas had the situation when there was a power outage, and had only cordless phones to hand, and thus no active landline phone (and didn’t have a charged cell phone either). They finally dug out an old corded phone from the “storage” area in the garage...) and thus had an active phone.... They now have at least one corded phone in circuit at all times; which is in the bedroom in-case of emergency. Friends in SLC do likewise; as do I (currently back in UK).

The way fixed (POTS) lines are distributed has changed over the last 20 years. Originally copper lines ran from a telephone building, equipped with battery backup and (depending on size/importance) generator. Standard battery output covers 8 hours, although that will depend on the age/condition of the batteries.

Today, curb-side cabinets are the "last mile" copper link between home and exchange. The cabinets are connected to the central exchange building using optical fiber (some older systems could use coaxial cable). This makes it possible to supply DSL service at a reasonable speed to customers. However in low density populated areas, that "last mile" could become miles. The cabinets also have battery backup. If your power interruption last for more than a few hours, don't be surprised your POTS line is also dead.

It used to be longer than 24hrs. for maintained telephone supply volts to “survive”... but as per sluc that seems to have changed.

I dun a bit morer research and found:




This US consumers report makes interesting reading; at least as it applies to the US...


Seems that in the US (and likely elswhere too) it all comes down to cash...

In the UK it seems BT, who service the actual wiring..., now provide 6hrs backup - for copper lines; there is none for fibre...

I should apologize for the thread hijack but the OP doesn't seem to care so here comes a little more.....*G*

That last post of trvlr's made me laugh. The whole keeping a land line for emergency thing rung a bell.

Background: My wife is takes medications regularly on a daily basis so we invested in this cool pill ogranizer system called PillDrill:


Anyhow, it works through our smart phones. Simply install the app on your phone and when she's due to take her med's an alert goes off on her, and my cell phones. Also, while I'm away, on her daughters phone too. Scan the pill organizer for that time and it updates, via the app, that she has taken her pills. So now matter where I am, I have confirmation whether or not she's taken her pills at the right time.

So, last November I was away on my yearly hunting trip out west and one day shortly after 1 pm I noticed my wife hadn't taken any pills yet that day. Worried, I tried to call her.........no answer. Needless to say, I'm getting VERY concerned and upset. So I called my friend at work who just lives a block away from me (we had prearranged for him to be my emergency contact should someone need to go over to my house and check on my wife) and he went over to my place. While he was driving there, I tried calling him on his cell a couple times and got no answer so I tried another friend who lives about 20 miles south of town. I got through to her and she told me she'd heard that someone digging in town had cut a major phone line which killed cell service in our area. I confirmed this by calling a few people at work on their cells and started to relax

15 - 20 min's later my friend phones me from work to report my wife was fine and taking her meds on time....and then he says, "Oh yeah, I totally forgot our cell phones are dead" Duh! LOL

The fact that I could call him on his desk phone (a digital set) confirms that the landlines were indeed working while cell service wasn't. Granted this was a bit of a fluke but it could happen anywhere else at any time and for the duration (around 12 hours), there were a lot of people unable to make phone calls. The first thing I thought of after hearing that was how screwed you'd be if you had a medical emergency and tried to call for an ambulance and all you had at home was a cell phone.

So back to my bell ringing......one of the links posted was titled "Should you keep a land line for emergencies" (or something to that affect) and I'm now back to considering having one again! LOL
