WiFi Issue

Postby Jam Master J » 2017/08/26 11:59:05

Good Morning,

I'm new to Linux- spent yesterday evening and this morning installing Centos 7 on a 10 year old Gateway laptop- dual core Pentium

Issue is no Wifi

I'll spare everyone the details of my journey up to this point unless someone asks.. But at this point iwconfig works and shows:

lo no wireless extensions
virbr0-nic no wireless extensions
virbr0 no wireless extensions
enp6s0 no wireless extensions

From what I've read, this means I need a driver- correct?

I have a Marvell Technology Group Ltd. 88W8362e [TopDog] 802.11a/b/g/n Wireless (rev 03)

and Marvell doesn't seem to have it.

Am I on the right track in general at this point?

What next? Try a 64 bit Windows driver?

Thanks!

What is the output returned by:

lspci -nn | grep -i net

Good Morning,

I get the Marvell controller above and also-

6:00.0 Ethernet Controller [0200]: Realtek Semiconductor Co., Ltd. (This one works- I was able to plug into my router/modem to do yum stuff)

Also I said I might try a windows 64 bit driver, but there isn't one at Marvell for 88W8362e. Now I'm thinking I could try a few of the Linux 64 bit Marvell drivers?

Yes but we need to see the output of the exact command lspci -nn | grep -i net so we can see the PCI vendor and device ids. If you run lspci without -nn then it doesn't have the information we need to be able to assist you.

I tried to install Marvell's Linux Driver- the only Linux one they had (sk98lin) and its telling me that an alternative Marvell driver is already installed and I could use that. Does that sound feasible?

Pretty sure sk98lin is for wired cards not for wireless. I checked the 7.4 kernel in the CR repo and it has no module that supports 11ab:2a08. Based on a quick search, it would appear to me that there are no linux drivers for this chipset at all - which means you either need to work out how to use ndiswrapper and extract a copy of the Windows drivers to use with it... or you give up, chuck it in the bin and spend some money on a supported card (sorry). I bought an Intel half height mini-PCIe 7260 (or 7265, can't remember) card from a well known auction site for under £10 and that works out of the box and gets me speeds up to 867Mbps.

Thanks. I guess it was true then. My NIC does work.

Plan B- I just plugged a Belkin dongle I had lying around and it seems to at least recognize it. Network shows "USB Ethernet" and it says connecting but its not connecting.

So does this mean I have a driver?:

iwconfig shows:
enp0s29f7u1 unassociated Nickname:"rtl_wifi"
Mode: Auto Access Point: Not-Associated Sensitivity:0/0
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invlid misc:0 Missed beacon:0

if not, then lspci shows the first two from before plus:
06:00.0 Ethernet Controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101/2/6E
PCI Express Fast/Gigabit Ethernet controller [10ec:8136] (rev 01)

tried a few lsmod greps
grep real shows ums_realtek and usb_storage so maybe wrong driver?

Thanks for any help you can give!

For a USB device, you run lsusb to see the device IDs.
