AP205 can't access ssl web

I have around 158 AP with 802.11N AP100 series + controller 6000. Its work fine. After I change some to AP205 802.11 AC . Some web can't access . I found all of them is SSL such as google, yahoo. I try to provision them and hope it will work but not. For normal web, it work properly. I can ping , tracert to those SSL web but it won't show on browser seem like AP205 block this web. I change the computer both PC & MAC but its doesn't work.  Does anyone has this experience before?

Can you verify whether you have a custom MTU set on your AP System profile?

Re: AP205 can't access ssl web

The ap configuration group which I use , it was used on old 802.11n & AP205 AC. As I mention earlier, it has no problem with AP105 802.11n at all. Currently, SAP MTU set nothing, RAP mtu = 1200. I think its default setting.

However, my vendor will coming tomorrow to check what we will do to solve this. I will mention this MTU to him.

If it is not set, then you should be OK.    I had a customer that had issues getting to certain sites with AP-205s; but like you, their older AP-105s were fine.  In there case, it was an MTU issue set by the customer.    If it continues after you  consultant is onsite, I'd recommend you open a TAC case.

Re: AP205 can't access ssl web

WOW , I create temp profile and provision.

 

I change RAP MTU from 1200 to 1500 , still has a problem

 

I add SAP MTU from nothing to 1500, now SSL web working ! problem solved !

 

However, I am not sure my configuration is correct, this number 1500 I assume from some answer in aruba community, not sure it is a right thing. Currently , RAP MTU 1200, SAP MTU = 1500. 
And if I apply this configuration to AP105 802.11N, is it will create a problem?

Re: AP205 can't access ssl web

Ok for making sure problem will not happen to old AP105, I create 2 profile. First profile SAP MTU = nothing for AP105, Second profile SAP MTU=1500 for AP205.  This solved problem for access all SSL web such as google, yahoo.com etc...
