IETF62 Wireless Network Update

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Gentlepeople,
We just wanted to give everyone an update on the state of the wireless network here at the Hilton. As most people noticed, we had severe problems involving APs going away starting right around 9am when the first meetings began. We identified and worked around the problem and the APs have been up and reasonably solid since mid-morning.


However, despite the APs staying up, we continued to see problems, particularly on the 3rd floor. Common symptoms were:
- Long delays before receiving DHCP responses
- Long first hop round trip times
- Loss on the first hop (in the wireless domain)
- Receiving a DHCP address, but still not having the ability to contact the default router


Moving forward, we've made several configuration changes which should help matters, and we believe that most of the problems have been resolved. Please (gently) let us know if you're still seeing major problems. The 2.4G band (802.11b/g) is still pretty congested and has some inherent issues in a situation like IETF meetings, so if you have the option to use 802.11a, we'd suggest you do so.

As always, any trouble reports or questions can be directed at ietf-62@xxxxxxxxx

Again, our apologies for the frustration and annoyance this is causing. Believe us, we want to get this to work just as much, if not more, than you all do!

	- Jim
