loosing connection to the ISP

RouterOS General
1

hello

I have local wireless network connected to internet
I am using Mikrotik 2.8.26, Prism 2 card in ap-bridge mode (200mW) and Atheros 5213 card for link to the ISP
I have a problem:
during loading in local (playing games etc.) I am loosing connection to the ISP

I believe that the problem lies in Mikrotik settings

wlan1(local) ip 192.168.100.1/24
wlan2(ISP) ip 10.5.51.214/24

routing settings:

ip routes gateway 10.5.51.1
ip dns static 10.5.51.1
ip firewall source nat masquerade 198.168.100.0/24

I have adjusted hotspot,which is functioning well

I am so sorry for bothering you, but I am still a beginner in this field
Looking forward to your answer

Is your local hotspot Prism 2 card on a different channel to that of ther ISP link? it should be eg:

ISP Chan 1, Hotspot Chan 6
ISP Chan 1, Hotspot Chan 11
ISP Chan 6, Hotspot Chan 1
ISP Chan 6, Hotspot Chan 11

etc

isp chan 3, local (prism2) chan 7

Your gw IP is the same that IP in wlan2???.
…
When you lose connection, try to test the link with ping or traceroute to any IP in internet.

It’s ok…
Test ping & trace when you lose connection & paste results…
tks.

Which wireless channels are you using?

What signal levels do you have?

9

for isp connection channel 3, tx/rx rate: 11 mbps, tx/rx signal streigth: -71/-64 dbm

ap (prism card) channel 7

10

The channels being used looks OK to me.

Are you able to play games etc or download a large file from the ISP/Internet using a wired connection to the MikroTik without disconnection from the ISP?

Sorry for all these questions I’m trying to eliminate possible problems one at a time.

i am able,and the download goes fine,using wired
connection,and wireless from the ISP over Mikrotik,until I load Prism 2 card,
and then Atheros card simply loose connection (it looks like that the ISP dont
even exist!)and it look for it for a short time,then make connection for a
while,than loose again…and all that again and again during forcing in the local
i doubt that some packages are going throuhg from the local to the ISP and
roam ,or somethimg like that…

anybody, plz :frowning:

I have had exactly the same problem due to interference from an access point based on the Prism 2 chipset. I moved the access point to another location and that solved my problem. The only advice I can give you based on the information I have so far is to attach an external antenna to the Atheros based wireless card and place it as far as you can from the Prism 2 cards antenna.
