Wi-fi UK and US - parthiban - 08-03-2018
Are there any differences between wifi in the UK and US? As you may remember my sis got a Sony laptop just before xmas which was for her to take abroad as she's currently studying in the cayman islands. The laptop worked fine over here, but while we were at our place in Florida it had real problems connecting to the wireless router there - we ignored it assuming there was a fault with the router or internet connection there (which as it happens there was!)
However, she has continued to have intermittent problems with making it connect for the last few months she's been out in the caymans, but now it's back in the UK it locks straight onto my router and has a totally solid connection.
I'm thinking of taking it back to Sony saying it's faulty but just wanted to check is it a problem with the laptop or are there differences between wifi over here and across the pond? And if so to reduce problems would it make sense to just buy a US laptop?
I've spent some time googling this but can't seem to find anything about anyone experiencing similar difficulties............

could it be down to different wifi rates ? for example 801.2b or what ever the change in letter is lol

The laptop in question is 802.11b/g/n compatible so the standard shouldn't be the issue, but I know we use 2.4Ghz I think, do the yanks use a different frequency or is it the same? In any case people don't generally have problems taking laptops to different countries so it's a bizarre issue........

Pretty sure that there are a few channel difference between different countries, i.e. which channels of the 2.4 GHz spectrum are used. But not sure that would be causing the problem you describe.
Edit - just checked, 11 channels are used in the US and 13 in Europe.

Isnt there a difference, and thats why the Ipad has been banned in Israel cause the US uses a stronger signal or something?
Wi-fi UK and US - steviewevie - 08-03-2018
Don't know anything about the iPad/Israel thing, but the only real difference is that Europe uses channels 12 and 13, so if your laptop was set to use those it wouldn't work in the US (which only uses channels 1 to 11) unless you changed channel. But vice versa (a laptop from the US brought to the UK) should be ok.
Edit - I see that the iPad thing is about US devices being allowed to transmit a stronger signal compared to Israel and Europe, as you say Stav.

thats what i meant, knew it was something to do with Wireless

Just thinking, but was she always in the same place, using the same wireless router etc in the Caymans, or was she travelling around ? Could it just be that there were interference problems with other people on the same or overlapping channels near where she was using it in the Caymans, but when she comes back there is less interference ?
Although there are 11 channels you can use in the US, actually most of the channels overlap with other channels, so they're not really 11 totally separate channels. There are actually only channels 1, 6 and 11 that don't overlap at all with each other, so most use one of those.

Ok having dug a little deeper, it's starting to get a bit clearer - it isn't now a problem all the time, the wifi seems to work fine everywhere except when she's actually in the university. It's fine in her residences, and elsewhere, just the uni network causes problems.
It connects to the network, but says no internet access. Apparently they came up with a fix where if she types the actual network address 192.168.1.1 into the address bar, it then connects up fine - can anyone explain why that is?

Sounds like an issue with getting DNS addresses to resolve from IP addresses... Presumably she's using Windows, in which case it's worth checking her network settings - is it set to allow the network gateway to act as a DHCP server? If not, then this might allow her to correctly resolve the network addresses..
I'm no network admin, but this is all I can think of to check...
