Re: [93attendees] Hilton Guest Room Internet Update

The problem is that the wired connection does not work in my room and the response I got after talking with the hotel vendor was use the wireless one which of course does not work. 
This is the worst network experience I had at an ietf meeting hotel

We know the guestroom Internet here in the Hilton has been problematic at best, and we have been working to try to improve it for the last week. As you probably know, the IETF network provides the IP layer and above for the guestrooms and public space, but the physical layer, both for the wired and wireless uses the existing hotel infrastructure. In the case here in Prague, we’ve been working closely with the hotel’s vendor, Mikenopa to deliver this service. They’ve been very willing and happy to work with us on this.

While the APs seem to have been originally deployed reasonably, there has been hotel building changes (mostly regarding new sprinkler systems) which has had them moved around in the hallways to very suboptimal locations. This has led to many areas having low to no signal. Additionally, their 2.4G channel assignment and power levels weren’t optimal. Mikenopa has been trying to move APs and reconfigure the channels.

This is based in the fact that we’ve got a large block that is sparsely used, and thus when we get scanned (as happens constantly from the greater Internet) we get a large amount of ARP traffic which can overload the wireless system. We’ve been working on various techniques to reduce this load.

Please do use the wired connection in each guestroom if at all possible. If you need a cable, it’s usually in a cloth bag with a “@“ symbol on it in the desk. If you don’t have one, please feel free to come to the NOC.
