issues when ios connected

[yorgos]

hello

i am using  a D7000 modem-router and an EX2700..i have connected some android devices,a windows pc or two and things are doing good and smooth...when an ios device gets connected (in my case iphone 6 an/or ipad air 2),connection looks like unstable..ping goes high,slow loading etc.sometimes even link led goes red for a few seconds..all that only when an ios devices is connected...what could be the cause?

(firmware 1.0.1.48)

Hello yorgos

Have you checked the logs of the D7000 see if anything odd sitcks out like DOS attacks?

Hello,thanks for your reply..

I just checked the logs, i see lots of [DoS attack: ACK Scan], different sources.. can we get something out of these? I might need some help with that

[DarrenM]

Yea we would have to look at the IP address from where they are coming from and figure out if some app on your IOS devices are causing the issue.

Sounds right..

so there are maybe hundreds of them, looking like that:

and the list goes on...how can i find the cause with all these ?

[DarrenM]

If you take the Ip address and put it in your web browser it sometimes can tell you where its coming from like the 185 address is some shoe sales website.

Another one is Facebook.

I use this to check things:

>>>> IPNetInfo: Retrieve IP Address Information from WHOIS servers <<<<

[yorgos]

[yorgos]

Any ideas...??
