Slow WiFi for HP4720s, Ralink RT3090 [SOLVED]

Postby vn32427 » Sat Nov 14, 2015 9:39 am

Hi There :)

tl;dr -- WiFi works but very slow, whereas Ethernet works fine. Multiple troubleshooters did not help, and I'm not sure about the driver I need

Long time reader, first time writer, and generally new to Linux Mint. I have a relatively fresh install of Linux Mint 17.2 Cinnamon Refaela, and the WiFi used to work fine, but now it doesn't.
Options considered and eliminated:
- not router as other devices work fine
- not Internet connection as a cable connection is very fast (240mb/s vs. 0.3 mb/s with WiFi).
- system is fully updated

I have read several guides on the subject (eg. https://goo.gl/jiQNhc) but at the moment I'm a bit confused in regards to my physical WiFi card: on the one hand HP says that my model, 4720s, has Atheros 9285 (http://h20564.www2.hp.com/hpsc/doc/publ ... -c02057767) but on the other hand some reviews (eg. http://www.notebookreview.com/notebookr ... 0s-review/) says I have the RALINK 3090. Running some commands on terminal say the same, but I consider the possibility that I just got the wrong drivers (not sure how). My BIOS isn''t being too helpful...
So my first question would be: how do I know what card I actually have?

inxi -Fxx says:

Code: Select all

Network:   Card-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
           driver: r8169 ver: 2.3LK-NAPI port: 2000 bus-ID: 45:00.0 chip-ID: 10ec:8168
           IF: eth0 state: down mac: 64:31:50:06:88:16
           Card-2: Ralink RT3090 Wireless 802.11n 1T/1R PCIe driver: rt2800pci ver: 2.3.0 bus-ID: 44:00.0 chip-ID: 1814:3090
           IF: wlan0 state: up mac: e0:2a:82:1b:11:52
           Card-3: Ralink usb-ID: 002-003 chip-ID: 148f:1000
           IF: N/A state: N/A speed: N/A duplex: N/A mac: N/A


and also, sudo mintwifi says (I've omitted irrelevant output):

Code: Select all

-------------------------
* I. scanning WIFI PCI devices...
  -- Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe
      ==> PCI ID = 1814:3090
-------------------------
* II. querying ndiswrapper...
-------------------------
* III. querying iwconfig...
eth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:"Jerusalem" 
          Mode:Managed  Frequency:2.437 GHz  Access Point: 64:7C:34:8E:1D:E9   
          Bit Rate=1 Mb/s   Tx-Power=20 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=70/70  Signal level=-23 dBm 
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:174  Invalid misc:2803   Missed beacon:0

lo        no wireless extensions.


As far as I can tell the settings are "correct" in the sense of disabling encryption key, power management etc.
At this stage I would mostly want to just re-install the driver, but I'm not sure how to do that: where and how do I get the driver for my network card?

Note that most guides and tips refer to non-functional WiFi, but here's the case is a bit different, just slow...

Many thanks for your help -- and let me know if I can post anything else that could provide useful information :)

Shalom Aleichem! :)

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

You could try the following:

1. Disable IPv6:
https://sites.google.com/site/easylinux ... able-IPv61
(item 2.2, right column)

2. The easy generic solutions, which should give you a newer driver for your wireless:

a. Install the latest kernel from the 3.16 series:
https://sites.google.com/site/easylinux ... el-updates
(item 3, right column)

Then reboot.

b. When no improvement: install the latest kernel from the 3.19 series.

Then reboot.

c. When no improvement: install the latest kernel from the 4.2 series.

Then reboot.

d. When still no improvement: check for a newer BIOS / UEFI and when available, install it.

Does this help?

Hey, it works now!!
Step 2.a resolved it. For the record, I had to fiddle with a terminal command to allow the updates (I think it was sudo --configure -a or something like that), but the OS itself told me to do that -- really straightforward.

Thank you so much, I was about to give up on Linux :)

Cheers,

Hi Pjotr,

Unfortunately the issue persists -- not sure why I thought it was resolved :(
I've done all the steps up to updating Kernel to 4.2 (inclusive), WiFi still just as slow.

I'm considering the BIOS updates [http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=4145331&swItemId=ob_98202_1&swEnvOid=2020#tab5 and http://h20564.www2.hp.com/hpsc/swd/publ ... =2020#tab5] but I'm not sure about this...

1) Are these updates are related to the issue? when I read the details, they don't say anything about the network card.
2) Linux Mint is not on the list of the supported OSs; are we sure it would make a difference? :)
3) I'm not sure exactly how to update the BIOS; the .EXE files I downloaded seem to be Windows-y :)

Note that my current BIOS is older than these updates; it's from 2010 and the two updates are from 2011.

If there's a different way to update the Network driver / hardware only?

Thanks again!
- Ehud

It might have nothing to do with your OS.

I've seen various laptops have issues with certain wireless channels.

First, is your router dual band? (ie it broadcasts "Wifi 2.4" and "Wifi 5G")

If no, keep reading.

Traditional WiFi uses 11 different channels to broadcast on. I HAVE SEEN laptops that, for example, crawl on channel 1 but internet is much faster on channel 9.

Open your browser. In the URL bar type 192.168.1.1, or 192.168.0.1, or 192.168.10.1 (depending on your router). One of those SHOULD take you to your router settings. Off hand I only know how to get into Netgear routers, and the credentials are admin/password.

Find your wireless options and look for Wireless channel. You should have options of 1 thru 11 (13 and 14 if you're in Europe)

At this point, it's trial and error. Choose a channel, hit apply, and it will kick you off. Sign back on and run a speed test. Wash, rinse, repeat.

If all of them fail:

Create a USB Bootable of any linux distro and run a speed test to see if it isn't some whacky setting on yours. If you get the same result I'd chalk it up to a bad wireless card.

My desktop has a small USB wifi adapter I got on eBay for like 5 bucks. I pull atleast 20Mbps on a regular basis. It was pretty much plug and play on Linux Mint. I'd recommend that as an alternative.

Hope this helps!

Update: for a long stretch the WiFi was perfectly fine (ie. fast!) but last night again, it dropped to an anguishing ~300bytes per second.

So, I tried the Channel trick -- the router was set to "set automatically [6]", which means that when I encountered the slowness it was on ch. 6.

I changed it to be manual, [7], and voilà! the speed immediately went up to normal (~2mb/s). Did not require a restart!

I'd like to think that was the issue all along, but it's possible there were several "root causes" here.

Hopefully, no more updates; but if it breaks again I might come back here.

Thanks all!

keep me posted. I've worked in telecommunications for years, you'd be surprised how often I run into channel issues.
