[Strange Problem] Wireless network and PTCL dsl


#1

Dear WP friends,

I am having strange proble with my wifi network.

Network:

PTCL DSL Modem -> WiFi Router -> Laptops & other wirless devices.

Issue:

Browsing stuck again and again, PING time varies from 1ms to 1100ms.

What already tried:

1- Change of Dsl Modem and Wifi router, but problem remain the same.

2- PTCL Dsl works fine when i use it with Lan Cable (PING 1ms constant), but problem appears when i use it with wifi router.

3- DSL Modem on DHCP (Gateway 192.168.1.1)

4- Wifi router with DHCP enabled.

any idea, what is wrong?


#2

Your wifi router is the issue here.


#3

yousaf465 Thanks for your reply

As i said, i have already replaced my Wifi router, but no use...Previous one was TP-Link and now Airlive with same problem :(


#4

Disable the DHCP on your wifi router use it only as a AP, and keep atleast a distance of 10 meters( if possible ) from your wifi router. Which tp-link were you using.


#5

Problem seems to be resolved...

Ok now what i did is to hang wifi-router on the wall [now distance is appx 1 meter from DSL modem]

previously wifi router was sitting on the DSL modem:(

Thanks Yousuf.

Select DHCP in your wifi router and select disable. Your setup should be like this DSL modem----some distance----Wifi router----10m-----your pc.


#8

:(

No use...

thinking of wires again...


#9

that so strange never seen before like this


#10

which card you are using in your desktop/laptop.

It amuses me to see people blaming DHCP.

DHCP is not going to shoot your pings to sky.

:P

===

On the topic. Are you running any other wireless devices? For example a cordless phone or anything else that runs on the same or similar frequency.

may be a microwave?

Try changing the wireless channel, choose 11 and see if that makes any difference.

-=====

Also do a traceroute from your computer when you hacing this issue and paste it here and we will see where the latency is spiking.

Cheers!

Iz!

DHCP does shoot the net down to zero if improperly configured. changing the channel might help.

Can you please do a couple of trace routes when this problem occur and paste them here?

Well from trace route it doesn’t look like your wireless. 116.71.32.1 is a PTCL’s ip address and looks like a L3 switch to me.

unless the situation lasts for seconds and by the time you were doing the trace route it was all good again.

but from the above trace route, all the latency is on the international links.

192.168.1.1 is your adsl router not your wireless ap/router right?
