Lenovo tablet won't connect to hotel wifi

It could have been that your IP had expired and the DHCP server had run out of new addresses.
Here in London, every time I'm at St Pancras station, if I see too many people on the platform I already know that I will struggle to get a connection. On off-peak hours, it connects in seconds.

So is there anything you can do about that if it happens again

Not really, you could try and use a static IP address, but you will need to know in advance all the settings and it could still not work. You will have to wait until a new IP gets released and becomes available.

Just to be clear, I am not saying that this is what happened to your tablet, just saying that these sort of things are quite common with WiFi hotspots.

Thanks, just trying to understand techy things a bit more. I am not on holiday until may 2019 so i can cope if this happens if i am just out for a few hours in a public place.

^^ bad advice for public or commercial infrastructure. This could create duplicate ip on the network. Secondly if you inadvertently put the gateway address as the ip address you could reroute all the traffic to your device bringing down the whole of the network for everyone your side of the gateway/router.

____________________________________________________________________________

On a separate note: ip cards there is a hardware address known as MAC Address. this address is 12 hex digits long of which the first six digits are manufacturer's id and is used to assign an ip address to the computer.

Often these addresses supposed to be unique, but now not always. it is possible to ban communications of devices that use a specific mac address, If you ever visit an area where they have '1 hour free internet access only' then it is usually mac filtering. Often you can change this address.

If I had some person trying to hack my network, or download too much, spending too many hours on-line, MAC address filtering is probably the easiest option

Also a decent wifi hotspot in a coffee shop can handle about 40 users, close vicinity and lowish usage. The number or thoughput drops if all want to watch hd films though.

If you read what I wrote slowly, you will notice that I specified 'you will need to know in advance all the settings'. That includes: what IP address to use, what subnet mask, what gateway. I never said 'take a random address and use it'.

I don't understand why you mentioned MAC addresses, I was talking about IP addresses from DHCP servers, I never mentioned or suggested any change in the MAC address.

From what OP said, I don't think he was trying to hack into the hotel's network, so I really doubt that they would have blocked him for that.

Wireless access points can very well handle 40 clients, but if you run out of addresses, you won't be able to connect even if you are the only customer in the store.

I have just tried to log onto the cloud in wetherspoons and it didn't work. Working now I am back home

arciere I have seen seasoned pros mix up the gateway and ip, more than once too.

Even if the person does know all the details, these will have been supplied by dhcp. if you put in a fixed ip the dhcp will still see its exact same ip as unused and re-issue it, having 2 pieces of kit with the same ip is not good.


that mac address has go nothing to do with what you said, but it offers a way of limiting or banning people even if you do not know the ip, but since it is not working anywhere it is probably not that.

I did not say the op was hacking the but if someone else on that segment was, and there are two addresses, the easy solution would be to ban those two, the guests will be gone in a few days anyway, and wifi is known to be unreliable ... only a supposition, that the hotel people are mostly non technical, bet they get lots of complaints about wifi, and the easiest solution is often the best

if this does not work would suggest check ms updates. If that does not work then new drivers from the network card manufactures site, and check their version[/STRIKE]

Because it's logging on to your home router not the "cloud"

Sorry i am confused, i dont understand how this relates to my lenovo android tablet.
I have not been hacking into any computer network, i have been on holiday in greece with a fairly new tablet. I have logged into the free hotel internet for 1 day and and then found problems after that.
I have sat in wetherspoons pub and tried to log into the cloud. I cannot do either.
Do i need to factory reset on my tablet or return it to the manufacturer or anything else.

Sorry I did not see anywhere where you said Android, and took it as a windows one. I see arciere subtially mentioned it on #18

other can easily steal your computer id and mimic your device. Also if there is another person on that shared network segment, it could be easier to isolate the segment. I am not blaming you

You have tried a long finger press on he wifi button which brings up all the wifi networks and allows you to select the one want?
