Hello ranyodh, there are some recommendations you can try prior considering hardware replacement:
- Make sure both the computer and the router are using the exact same wireless encryption; such as WPA2-AES instead of TKIP options. Intel WiFi Products — Data Rate Will Not Exceed 54 Mbps When WEP or TKIP Encryption is Configured
- Use the least crowded wireless channel in the 2.4 GHz band, or use 5GHz. Intel® Wi-Fi Products — Possible interference by other wireless devices may impact 802.11n performance
- Update your router’s firmware.
In regards of the hardware we suggest contacting the system manufacturer because of the chance of hardware integration failure and because they should know the validated wireless adapter models that are compatible with your system.
- I am using WPA2-AES (for router and computer)
- I scanned the wireless channels, and I am using channel 11 (which is not used by any other wifi signals)
- No new firmware update for my router (DPC 3825)
I have contacted Dell's support regarding this. No answer from them yet.
Again, the reason I am posting here is to get suggestions from other people of what adapter I can use to replace Intel's one. I have spend long time trying to read ALL the posts in that other thread about this adapter (you closed that thread claiming the issue was fixed), tried everything from that post, tried everything I could find in Intel's forums.
I am just too fed up to give it another try. Just want to replace the damn thing now.
