WIFI Problem

Hello,


In first, sorry for my bad english, i am French and happy owner of GPD pocket

My wifi card seems to have some problems.

- The signals are very low
- I see other networks wifi but i do not capture my network while my other elements work very well


I have the latest drivers 1.558.53.15
I have read this topic : https://www.reddit.com/r/gpdwin/comments/5wgc14/wifi_problem/

Have you got an idea ?


Thank you

Your wifi was faster before apply windows update? If no, you can try open GPC Pocket (it is very easy) and check antennas connection. If you will shill have this problem, problem is in drivers and you can try search newest or wait to new drivers from broadcom.

Hello,

I had open the GPD but antennas is ok.

Have you got an another idea ? Maybe It is a hardware problem ?

Am i alone with this problem ?

Out of the box, WiFi signal was weak, 5G bands do not show, and could not connect.  This is before any Windows updates!  Had to connect to Internet using a Ethernet dongle through the USB port.  I also ran through all Windows Updates to OS Build 15063.483, so got driver version 1.558.53.15 for Broadcom 802.11ac Wireless PCIE Full Dongle Adapter (might need to separately do "Update driver" under "Network adapters" in Device Manager to get latest driver version), but suspect those steps are not necessary.

Fix found!

1. Download https://mega.nz/#!VUZx1AAb!XdDyLUbytthJ832RZfxGFrMCS2RxyWPjLOmJvi4Zf0E (for US Backer on http://www.gpd.hk/news.asp?id=1519&selectclassid=002002 ; but you don't need to know that).

2. Extract 4356r2nvram.txt using RAR Opener from Microsoft Store.

3. Copy 4356r2nvram.txt into C:\Windows\System32\drivers (using Ctrl-C then Ctrl-V) by enabling admin permission (just answer "yes" to activate for this copying process).

4. Reboot.

Now signal is strong, 5G bands show, connect without issues.

This procedure doesn't make sense at all, but it works!  Learnt different bits from different sources.  Wish GPD Support would just clearly state this fix.  Better yet, this file should be on the Pocket when delivered!!

This missing 4356r2nvram.txt is also https://1drv.ms/t/s!Amg9wimDZkLKbmU72-b2gV7zxoE for easy download and copying into C:\Windows\System32\drivers.

today I realized that the gpd pocket was not seeing wifi on ch 13
moving channel of router to 6 solved the problem
but further investigation lead me to modify the 4356r2nvram.txt and replace ccode=US with ccode=X2

now i can see also ch 13 :-)
