Received OSMC wifi-ac adapter - ISSUES

Help and Support Raspberry Pi
61

yes I tried both dhcp and static ip. Random working was only with DHCP mode. never got it working with static IP

62

Hi,

Is the wifi stick the only usb device attached?

Thanks Tom.

63

Did this only become a problem after an update? We recently updated to ConnMan 1.36 and some users reported some issues.

64

I tried on usb hub with power supply and directly plugged on raspberry piā€¦ same
usb device, I only have this wifi adaptater and usb keyboard plugged.

@sam_nazarko, I received my wifi adaptater 3 weeks ago and had this issue since the first day

65

What PSU do you have?
Can you post a log (run an Ethernet cable temporarily) when you lose the connection?

Sam

66

itā€™s official raspberry pi psu and dlink usb hub.
I donā€™t lose connection, wifi is connected but I canā€™t ping the gateway and itā€™s indicatedon wifi settings screen ā€œno internet conenctionā€.
If I plug ethernet, wifi indicates wlan0 (connected)

Hi,

I think it may be the WirelessMode, I believe any values after 10 are for AC; so you can try 11 through to 14.

Also you may need to adjust CountryRegionABand= values need to match AC Channels offered by your wifi router:

	    0: use 36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161, 165 Channel
		1: use 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140 Channel
		2: use 36, 40, 44, 48, 52, 56, 60, 64 Channel
		3: use 52, 56, 60, 64, 149, 153, 157, 161 Channel
		4: use 149, 153, 157, 161, 165 Channel
		5: use 149, 153, 157, 161 Channel

		9: use 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 132, 136, 140, 149, 153, 157, 161, 165 Channel
	   10: use 36, 40, 44, 48, 149, 153, 157, 161, 165 Channel
	   11: use 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 149, 153, 157, 161 Channel

Thanks Tom.

Mode AP
Network AC-Only
SSID dd-wrt-5-B
Channel 52 + 54
TX Power Auto
Rate 108 Mbps
Encryption - Interface wl2Enabled, WPA2 Personal Mixed

I canā€™t find 54 channel
CountryRegionABand is set by default to 7 so itā€™s ok for 52. I tried wirelessmode 13 or 14

69

If you canā€™t ping the gateway, maybe you have an issue with the default gateway. You could try:

route add default gw IP-OF-ROUTER

70

when running your command:
SIOCADDRT: File exists

Hi,

Now that a connection has been established, it may be worth trying the auto-configuration again.

sudo mv /lib/firmware/mt7610u_sta.dat /lib/firmware/mt7610u_sta.bak

Then reboot.

This is shown to have worked in the link I posted back in May.

Thanks Tom.

72

Working after retried the auto-confirgurationā€¦
I tried a reboot => OK
I tried hard reboot (unplug PSU) => OK

so I use this success connection to check ā€œrouteā€

the rate is not huge again half of 230Mbps announced by @sam_nazarko
If working tomorrow (XD) I will try Bluray stream

Anycase again a big thanks for your support

You will get 230Mbps in an ideal environment.
Your environment may differ however. WiFi is by its very nature quite hard to troubleshoot.

You will need 40Mbps on a Pi to play back Blu-ray (1080p is max on Pi).

Iā€™m back after few more test. I think the wifi dongle was set as wifi N and HT40 thatā€™s why lower perf than AC. on ddwrt router I used AC/N mixed mode.

If I set the ddwrt router in AC only mode, I got issue again with wrong IP address allocation (using DHCP)

not working anymoreā€¦ but working perfectly on my windows XD.

Which settings should I use to force AC mode?

75

Hi,

Thatā€™s strange, is the IP still within the correct ip range / subnet ?

Have you got wait for network enabled?

Also do you get AC if you set a static ip?

Thanks Tom.

76

DHCP router box range is 192.168.1.20 to 100 255.255.255.0
but I get 169.254.177.12 and 255.255.0.0

I can connect in AC mode only using wirless mode=14 in mt7610u_sta

when I try to set static IP, after click on ā€œapplyā€, IP address and subnet are reset to wrong IP
In addition default gateway and primary dns are empty

Hi,

Whats the make and model of the router, your are running ddwrt on?

Thanks Tom.

Checking with onboard wifi, when the dhcp is OK, I have ā€œConfigure Network Manuallyā€ with settings set in black police and status connected

So I guess with the wifi usb dongle Iā€™m in manual mode for settings cause I have ā€œConfigure Network using DHCPā€ and it stuck on it so DHCP resolution seems KO
