My Win10 tablet can connect ietf* WiFi, but can't access to the Internet

Description

My Win10 tablet (ASUS T100TAM) can connect ietf* SSID.
And my tablet can access the Internet a while.
But after a while (within a few minutes), connectivity to the Internet is lost.
I consulted Asai-san and we found that my tablet forgot router's arp shortly.

This trouble doesn't happen when my tablet connects to swissotel SSID.

I experienced this problem at IETF97@Seoul also.
Sadly, my tablet seems incompatible with IETF network :-(

Hi Yoshiro-san,
If you can provide us with H/W and driver information for your ASUS T100AM tablet we will be better able to explore any compatibility issues that may be causing this problem. Fell free to respond back or stop by the Network Help Desk in Vevey 3.
Thanks,
-Rick

We may have found a solution to this. Can you come by the NOC (40th floor) today so we can test? Thanks.

comment:8 Changed 21 months ago by jclarke@…

Actually, instead of coming by the NOC, Asai-san created a new SSID (ietf-legacy-test) for you to try. This is a non-broadcast SSID. Please join it (no auth required) and see if you experience the same issue. Thanks!

Dear NOC team,

Thank you very much for your wonderful support.
No I'm staying Zurich E&F, and trying to use 'ietf-legacy-test'.

The result is, my tablet can get WiFi radio, but it can't get IP 
address via DHCP server.

Regards,

I see that you were assigned 31.133.143.103 at 8:47 am local time. Was this before or after you joined this SSID?

comment:11 in reply to:  11 ; Changed 21 months ago by yoshiro.yoneya@…

Dear NOC team,

I think it was after I joined the SSID.  I tried the SSID again just a few 
minutes ago.  Still it can't get IPv4 address via DHCP server.

Do you get a v6 address with SLAAC? I don't see another instance of you trying to get a v4 lease in our dhcpd log.

comment:13 Changed 21 months ago by yoshiro.yoneya@…

I remember my password and logon here again :-)

Yes, my tablet got IPv6 address, 2001:67c:370:128:acfa:d50d:9ebd:9f62.
It can't reach IPv6 default gateway, so it can't access the Internet yet.

comment:14 Changed 21 months ago by yoshiro.yoneya@…

Dear NOC team,

Many thanks for your efforts.
My tablet got IPv4 address again, 31.133.143.103.
Unfortunately, no route to default gateway, 31.133.128.1.

At this moment, the situation is the same yesterday.

comment:15 Changed 21 months ago by jclarke@…

Hmmm, I thought the situation previously was you were associated and could pass traffic, but you were constantly dropped off the network. It sounds like what you're seeing now is different.

I've poked around Google a bit, and found people that seem to be having the same issue. Are you able to downgrade to driver version 5.93.98.207? But bottom line is this seems to be a known issue with this Asus tablet (see www.transformerforums.com/forum/asus-transformer-book-t100-help/41759-wifi-tips-tricks-problems-43.html ).

comment:16 Changed 21 months ago by yoshiro.yoneya@…

Dear NOC team,

Thank you for your suggestions.
I downgraded WiFi? driver to 5.93.98.207, and tried to connect ietf-legacy-test.
Sadly, it was not solved my tablet's problem.

I'm now in Zurich D and tried to connect around 13:15-13:30.

comment:17 Changed 21 months ago by jclarke@…

Good morning, Yoshiro-san. We made a wireless change late last night to eliminate excessive ARPs on the wireless. I recommend you give it one more try, but if this doesn't work, I think we need to resign to the fact that this may be an issue with this ASUS model/software/NIC, and it will not be something we can solve in the short time we have left.

comment:18 Changed 21 months ago by yoshiro.yoneya@…

Dear NOC Team,

Thank you very much for your wonderful efforts.
I tried to connect ietf-legacy-test again, and found that the situation was the same.
I abandon to use my tablet with ietf* SSID this time.
I apologize wasting your precious time.
I wish I can use my tablet at IETF99 :-)

Anyway, thank you again, I really appreciate your great work!

Regards,

Dear NOC Team,

I'm sorry posting again.
I seemed to find a work around.
My tablet works pretty fine with ietf-2.4ONLY both IPv4 and IPv6!
Perhaps, my tablet's WiFi? driver has trouble with 5GHz, even though it works fine in my house.
One side effect I found by using ietf-2.4ONLY is it mixed up with bluetooth devices such as keyboard and mouse.
But it is ok because BT keyboard and mouse are not mandatory.

Thank you for providing ietf-2.4ONLY and my apologies not tried it earlier.

Regards,

comment:20 Changed 21 months ago by jclarke@…

That is certainly a possibility. It could be that the card or table has an issue with range to the 5 GHz AP. Not sure how close you've been to one. Maybe it really needs a very strong signal. I'm glad it's working for you.

You have the workaround of using 2.4 GHz. Perhaps this can work for you at other conferences, too. Sorry we weren't able to find an answer for 5 GHz.
