RainFlying Posted February 6, 2014 Share Posted February 6, 2014 I swapped out the intel wireless card for a Dell DW 1702, and modified the AirPortAtheros40 kext. I can connect to WIFI, and it works, the signal seems to be weak. but after a long time, maybe not long but with a lot of network traffic, the connection drops. Is there something wrong with my card because I purchased a used one ? Or is this a common situation for Dell DW 1702 ? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 6, 2014 Administrators Share Posted February 6, 2014 Check your antenna connections. PS: no double posts please! Link to comment Share on other sites More sharing options...
RainFlying Posted February 6, 2014 Author Share Posted February 6, 2014 Check your antenna connections. PS: no double posts please! I checked the connection to antenna when I found the signal is weak. I think the connection to antenna is OK, both connecters are connected to the card firmly. Sorry, I mentioned the detail in that post, I think some people are using Dell DW 1702 with other notebooks. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted February 6, 2014 Administrators Share Posted February 6, 2014 sometimes you have to switch the antenna wires. invert the two connections. you should feel a light click when they seat onto the connector. also remove the wifi card and reseat that as well it might not be inserted fully.

What will happen if the two wires are not connected properly ? I can receive wifi signal, I think the wires are connected properly. Yes, I can feel a light click when I connect the connecter to wifi card. And the card is fully inserted to the PCI-E slot. Anyway, I'll try the original WIFI card later to see whether there is something wrong with this used card. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 7, 2014 Administrators Share Posted February 7, 2014 Once had a similar problem with a 2nd hand DW1490. Turned out the main antenna socket was no longer properly soldered to the card and one day I found the antenna cable in the air with the socket still attached to it. Card was basically goosed and went straight to the bin. Link to comment Share on other sites More sharing options...

RainFlying Posted February 11, 2014 Author Share Posted February 11, 2014 I might found what caused the problem. I compared the Dell DW 1702 and Intel 6235, the sockets of Intel 6235 is smaller than those of Dell DW 1702. I guess the connection is not so firmly as it appears, so should I meld the connectors to the sockets? Link to comment Share on other sites More sharing options...
