Finally got broadband sorted in the new house. Opted for Plusnets standard Unlimited 17mbps service.
We live on a busy main road where there are quite a few WiFi hotspots. Quite easy for someone to park up outside and try and hack.
Should we think about changing the wireless name and/or password to something completely unique, as opposed to that which Plusnet provides?

As long as its WPA it doesn't really matter what the ssid and key are, unless they send them all out with the same one, which I doubt.

as John says, they wont be the same, the ssid and password will be generated at Plusnet based on some variables I imagine. Dont worry.

No offence but who the fuck is going to want to sit outside your house in their underpants trying to hack into your wireless

If you are that worried about someone getting onto your wifi I hope you have all your hard drives and documents with full encryption.

WPA can still be cracked (bruteforce attack anyway) and most ISPs supply them with short passwords (my VM account used a 5 character password that could easily be broken within half a day), hence why you're better off changing the password to something that is reasonably long (15+ characters etc) - time taken for a bruteforce attack against a password https://www.grc.com/haystack.htm.

To suggest someone should use disk encryption for changing a password makes you look a bit of a tool Rob
For something that takes 10 seconds to change, it's a bit of a no-brainer if it makes your AP vastly more secure.

I've just have SSID broadcast disabled on mine. Don't really need it enabled once you're connected
But TBH, who's going to actually try and hack into your WiFi? If you're that worried about security you wouldn't be using it.

So what is changing the AP name really going to achieve? Instead of it being Sky3856837 its now going to be called MyAP
Even if you hide the SSID it still doesn't really do anything. If your AP is locked down with a password then thats enough to discourage any casual person trying to hack your wifi. If they are not the casual person they will be running a scanner anyway which will still pick up the hidden SSID.

I mentioned changing the WPA password (specifically, lengthening it to reduce bruteforce attacks) not the SSID, Rob.

One other point to remember - CHANGE YOUR ROUTER ADMIN PASSWORD! The Sky routers all used to have the password of 'netgear1' (or something) and TalkTalk have the really creative 'password' securing them. It's quite easy to have shenanigans if you get onto someone's network

The original poster was talking about changing the SSID thus my comment saying its not needed

Can you point me/us to this comment? Because the only one i see is your sarky response of using disk encryption to someone simply wanting to improve the security of their AP
Ed - Definitely! Especially if your modem/router has flaws like the VM Superhub where it (did; they might have fixed it) drops the WiFi security during bootup and where it's reasonably straight forward to force a remote reboot

Unless something has changed since I last read about it, you won't be doing 1000 guesses per second brute forcing a WPA password.
Only had a couple of minutes but just checked the status of rainbow tables for WPA. Because the hash is generated based on SSID and SSID length, they don't exist for every single possible SSID. If your SSId is plusnet178765689 it won't be there.
I think he's pretty safe.

If the SSID is indeed random (and not the default from manufacturer, in which case there's likely to be an 'off the shelf' rainbow table) then yes, the SSID salted password makes a rainbow attack incredibly difficult. But considering majority of GPU's can easily achieve ~80-100K PMK/s, brute forcing it is still a possibility.
Either way my point was, for ten seconds work to change the password it's a bit of a no-brainer if you can make your AP vastly more difficult to crack.
Similarly, WPS should also be disabled as that can be circumvented fairly easily - usually can be broken within a few hours (certainly within a day) using Reaver.

Unrelated to the thread but related to grc.
I had read for years about how good spinrite was but never had to use it in anger.
Tried it once on a drive that I ended up taking to a proper data recovery place, he wasn't happy with me, said it had only made it worse.

For clarification I asked if I should change the router named and/or password
And not particularly worried about it being hacked, just didn't know if the standard stuff is easier to crack than something I could come up with.
So in short there is nothing to worry about?
Oh and the router username is admin but the password looks like it is random generated i.e. not password!

Actually, turns out the router password is the Serial Number, so changed it to something different.

If you were worried about security why opt for a provider supplied router/modem in the first place

Sorry if I was a bit abrupt - Not a great weekend so was rather short with a few other people too
Changing a password is always a wise move (just don't loose it otherwise it could cost you like it did us at work the other day lol - £5.5K to unlock a Solaris machine!)
