Have you seen this problem with the MTU size being different even though the default coming from the switches is the same - 1500 ( we plugged a device into the switch directly and we were getting 1500, but when on wi fi in the same office we got 1400, so it must be the AP then, right?) and how to fix it please? Is it Meraki support who can help , who is the best person to resolve that issue? Thanks.
