MediaTek MT7630E connectivity breaks after connection

Hello, I am experiencing the exact same problem described here, although he is not the OP of the thread therefore I am starting a new post.

I am able to connect (I tried both Network Manager and manual wpa_supplicant + dhcpd) However, if I try some "heavy load", like trying to update the system, the connectivity simply breaks, i.e. I am not able to surf the web anymore. To get it working I have to shutdown and then power on, a simple reboot won't work.

Some info:

$ uname -r
5.1.7-arch1-1-ARCH


$ lspci -nnks 3:
03:00.0 Network controller [0280]: MEDIATEK Corp. MT7630e 802.11bgn Wireless Network Adapter [14c3:7630]

......

On a side note I d like to add that on the lts kermel (where the moules for this card are not provided) I am using the mt730-pcie-wifi-dkms modules found on the AUR and the card works properly


Please let me know if more information is required

Re: MediaTek MT7630E connectivity breaks after connection

You could try the mt76-dkms-git package, maybe that works better. I believe this is the upstream driver and has patches that are not submitted to the kernel yet.

Re: MediaTek MT7630E connectivity breaks after connection

Thanks for pointing this out.
Appearently, this pacakge conflicts with linux-firmware:

mt76-firmware-git: /usr/lib/firmware/mediatek/mt7615_cr4.bin exists in filesystem (owned by linux-firmware)
mt76-firmware-git: /usr/lib/firmware/mediatek/mt7615_n9.bin exists in filesystem (owned by linux-firmware)
mt76-firmware-git: /usr/lib/firmware/mediatek/mt7615_rom_patch.bin exists in filesystem (owned by linux-firmware)
Errors occurred, no packages were upgraded.

I thought it was safe to rename the original files (I hope I was right!) and so I did. Then another error popped up during the compiling:

(1/2) Install DKMS modules
==> dkms install mt76/r1466.b033532 -k 5.1.7-arch1-1-ARCH
Error! Bad return status for module build on kernel: 5.1.7-arch1-1-ARCH (x86_64)
Consult /var/lib/dkms/mt76/r1466.b033532/build/make.log for more information.

I am no C expert, therefore I do not know how to tackle this.

Edit: I just noticed that in the log files the lts kernel is mentioned, which is weird IMO

Edit2: please ignore the previous log file and refer to the following information:

Re: MediaTek MT7630E connectivity breaks after connection

Hmm, it seems like the detection of IEEE80211_HW_TX_STATUS_NO_AMPDU_LEN does not work as intended.
As a quick hack you can remove this from probably /usr/src/mt76-???/mt7603/Makefile:

ifeq ($(call check-cc-enum,IEEE80211_HW_TX_STATUS_NO_AMPDU_LEN,-include net/mac80211.h),n)
  EXTRA_CFLAGS += -DIEEE80211_HW_TX_STATUS_NO_AMPDU_LEN=IEEE80211_HW_REPORTS_TX_ACK_STATUS
endif

Re: MediaTek MT7630E connectivity breaks after connection

I did as suggested:

/usr/src/mt76-r1466.b033532/mt7603$ cat Makefile 
EXTRA_CFLAGS += -Werror -DCONFIG_MT76_LEDS

CHECK_CC_ENUM_FLAGS = $(NOSTDINC_FLAGS) $(LINUXINCLUDE) $(KBUILD_CPPFLAGS) $(KBUILD_CFLAGS)
check-cc-enum = $(call try-run, echo "int v = $(1);" | $(CC) -Werror $(CHECK_CC_ENUM_FLAGS) $(2) -c -x c - -o "$$TMP",y,n)

# backwards compatibility hack
#ifeq ($(call check-cc-enum,IEEE80211_HW_TX_STATUS_NO_AMPDU_LEN,-include net/mac80211.h),n)
#  EXTRA_CFLAGS += -DIEEE80211_HW_TX_STATUS_NO_AMPDU_LEN=IEEE80211_HW_REPORTS_TX_ACK_STATUS
#endif

obj-m := mt7603e.o

mt7603e-y := \
	pci.o soc.o main.o init.o mcu.o \
	core.o dma.o mac.o eeprom.o \

However I see the following error, which seems to refer to a different function:

Re: MediaTek MT7630E connectivity breaks after connection

OpenWRT has a lot of custom patches in their kernel. It seems like it is currently impossible to build the module for another kernel. The necessary patch hasn't been accepted yet.

Re: MediaTek MT7630E connectivity breaks after connection

oh I see. Therefore I could only wait for future releases, I guess, and hope to have an usable driver and in the meantime stick with the LTS kernel (hoping it wont switch to 5.x anytime soon).
