bgn not showing iwconfig

trdgrd · 2017-06-11 05:40:01

I have a toshiba satellite s955-s5373 which has a realtek rtl8188ce for hardware which I read that works with the driver rtl8192ce. but I was wondering why bgn protocols do not appear after running the comand iwconfig. I know that the hardware support those protocols and I do not know what could I do to make them appear or it is normal to be that way in my machine.here is the output of iw config.

iwconfig
enp1s0 no wireless extensions.

wlp2s0 IEEE 802.11 ESSID:"JOSE-MARIN"

lo no wireless extensions.

here is what I think it must be

iwconfig
enp1s0 no wireless extensions.

Use `iw` unless that driver is WEXT only.

But just what exactly is the problem? Why do you think the output should look like the second example? Is it actually causing you problems?

i think It may be the root of a problem. When I boot on windows the internet is faster than in linux so I suspect it is not recognizing the protocols bgn. And in many outputs of iwconfig that I,ve seen it shows the supported protocols that in my case would be bgn

seth · 2017-06-11 14:11:25

If strings can make the internet faster, I want more strings ;-)

Seriously, 72.2 Mb/s is the max. brutto rate for 2.4GHz IEEE 802.11
=> You could check the connection details on windows, notably if you've a running 5GHz network there (dualband is NOT mandatory for 802.11n - the HW may not provide that at all)

Otherwise you'll have to figure some details on "the internet is faster"™ because that's not a very precise condition description :-P

Ik.....I am doing some test now. When I ping 8.8.8.8 in linux i get values arround 122 and 90 but when I load for example a youtube video I get stuck for a minute in minute 2 of the video...and when I click on a new video It takes more than 2 minutes loading, I used chromium to test this. On the other hand when I boot on windows, videos load istantly each time i click on a new one. for this afternoon only me and a friend is using the internet. I made a test of internet in both systems and the result was the same.

youtube video

this can have a ton of causes which do not necessarily relate to your network throughput (and apparently your latency is relatively low, but expected?) let alone your WIFI. Ideally, you'd download from your AP/router, but for a quick test, run

wget -O /dev/null http://speedtest.wdc01.softlayer.com/downloads/test10.zip

trdgrd · 2017-06-15 01:00:16

so I reinstalled arch. I thought the problem was on a driver that i installed. I tested iwconfig in ubuntu and "wlp2s0 IEEE 802.11bgn" appears I do not think the problem is bgn not showing now. I am 8 meters away from the router and pages load so slow and sometimes just do not load at all but when I boot on windows pages load normally. DO you know a way that I can fix this I installed arch in all the disk so I do not have windows anymore. By the way seth the test gives me this

next to the router

158KB/s in 4m 22s

Ie. effectively only 43KB/s - looks like an unstable connection with a lot of package losses.

Try passing "swlp=0 fwlps=0 ips=0" to the module (this should disable all powersaving features)
It's however a connection problem for sure.

Edit: also please dump lspci & lsusb, there's rtl8188ee and rtl8188eu (latter in AUR)

ill try for today pass "swlp=0 fwlps=0 ips=0" to the module i guess I have done it before but lets see what happens. What I usually do is to create a file in /etc/modprobe.d/rtl8192ce.conf with options rtl8192ce swlp=0 fwlps=0 ips=0 . Is that right? I guess rtl8188ee and rtl8188eu are not compattble with my card. It is the rtl8192ce that also works for rtl8188ce. I have tried also installing rtlwifi_new-dkms but it I think is the same because last drivers were included in the last kernel update.

So i already tried swlp=0 fwlps=0 ips=0 and I experimented random disconnections even close to the router.

seth · 2017-06-15 19:57:56

Then i'm out of ideas. The chip is notoriously known to cause unstable connections, but generally the cause is the power saving.
Do you use any userspace tools for powersaving which might impact here?

Edit: you can use "systool -vm rtl8192ce" to check whether the parameters are actually set.

I use cpupower but I do not think it has to see with wifi. it is the config file of cpu power

I just set those parameter again (swlp=0 fwlps=0 ips=0) because of the random disconections. I had to turn wifi off and on again each time for it to work again.

seth · 2017-06-15 20:25:42

The parameters are applied, powersaving should be disabled (and cpupower alone have no impact)

Do you mean to say that the connection became more instable w/ powersaving disabled?

trdgrd · 2017-06-15 20:44:05

the conection is stable without those parameters and instable with them i tested close to the router and far 8 meters aprox. the result was the same, random disconections. just rebooted with those parameters and I have turned off and on again at least 2 times the wifi.

seth · 2017-06-15 20:58:41

Ok, then let's try the opposite:
Check iwconfig, if the txpower is still 20 dBm w/ powersaving disabled, try to lower txpower, eg.

iwconfig wlp2s0 txpower 15

and see whether the connection becomes more stable (or fails entirely if the value is now too low).
Notice that this is a logarithmic scale.

trdgrd · 2017-06-21 07:12:49

I tested what you said. The connection fails entirely. I tested rtlwifi_new-dkms from aur so I set

 options rtl8192ce_dkms swlp=0 fwlps=0 ips=0)

the connection was stable with power saving disabled and improved a lot. I just wonder if the module loaded is the correct because i think

 Kernel driver in use: rtl8192ce

should look like this

Kernel driver in use: rtl8192ce_dkms

lspci -nvvs 02:00.0
02:00.0 0280: 10ec:8176 (rev 01)

	Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-

	Capabilities: <access denied>
	Kernel driver in use: rtl8192ce
	Kernel modules: rtl8192ce, rtl8192ce_dkms

So i just unistalled rtlwifi_new-dkms and installed other drivers from this source Kernel driver in use: rtl8192ce .I think these are the same from rtlwifi_new-dkms but the name of these wont change like the ones i used before from aur. After

sudo make

and

sudo make install

I set the parameters

 options rtl8192ce swlp=0 fwlps=0 ips=0)

and it worked flawlessly. Connection is stable but,the problem disappeared when nobody is using the network but it comes back when someone is using it. I think computer takes less internet bandwidth than the other computers. I wonder why it might be because using windows I never had problems with the others using a lot bandwidth. I know it can handle with all the computers using bandwidth because once get closer to the router everything loads as it should be.

seth · 2017-06-21 08:16:14

a)

ips=0

- you got a stale ")" in there.

b)
you could try to increase the txpower, but i'm not sure i can just say how to do that here - depending on your regulatory domain, this can be illegal.

trdgrd · 2017-06-21 15:53:59

ho I maybe missclick, there is no error in the file I made. I have used this driver https://github.com/FreedomBen/rtl8188ce-linux-driver to get more txpower because it do not let me go beyond 20. and the driver in that page lets you set it in 30 or 33 changing regdomain to BO. In my case would be EC. this driver fails completely it is connected but does not load any page.

seth · 2017-06-22 18:58:39

Fails completely rightaway or after you went "I went to Bolivia just tried 33 dBm"?

The pattern you describe ("everything fine unless other people are polluting the EM band") sounds like your communication is blanketed by stronger signals. The maximum in EC should be 20 dBm, though.

The only other thing I could think of is that there're actually multiple APs on different channels and windows does a better job on hopping them?

trdgrd · 2017-06-22 19:19:25

the driver to set a higher txpower do not work on any configuration. There are 1 AP and the channel set for it is the 10th. Most of the other computers are plugged with cable. There are many routers in my building like each department has one all of them are in channel 1, I called the company in order to change the channel because my router was set in channel 1 also and they changed to channel 10. About 4 computers apart from mine are connected and I have no problems with windows just linux sometimes get pretty slow in loading pages and sometimes does not load at all. I know it is not ht network not the signal or the router because I always have near my phone and I loads normally also with windows normally I had more range in connection I mean that I could go further without losing wifi signal than the phone and now its backwards.
