Title: Wireless Issues with 860L
Post by: ddunlop07 on October 28, 2013, 04:38:53 PM
Hello,

Last week I purchased the DLink 860L and was able to set it up with no problems.  Almost instantly I noticed a problem with the 2.4GHz channel.  I updated the firmware to the newest version 1.04 and the problem still persisted.  I am able to connect to the 2.4 wireless, but within hours the wifi drops and I am unable to connect to it unless I restart the router.  I ran the wireless setup connection wizard and configured the settings similar to the 5GHz band (which I have no problems with).  Any ideas as to why this channel is performing so inconsistently?  There are no wireless phones or anything to interfere with the wireless that I know of.

I'm located near Detroit, MI.  The only factory reset I performed was when I first upgraded to firmware v1.04 after setting up the router.  I factory reset and then downgraded to v1.03 and am trying that now. 

I changed the SSID from the default to something original. 
Right now I'm testing the 2.4 on N only mode, and I have the 5ghz set to mixed ac,n, and a.
I am using wpa-personal security for both channels. 
The only devices connecting to the wireless is a laptop and two iphones (One a 5, one a 4).
No cordless housephones. 
No other WiFi routers in the area.

I am actually unable to disable ht 20/40 coexistence... I tried switching the 2.4ghz band to g only and set it to channel 11.  Been a busy week, though, I do plan on doing some more testing over the weekend. Will keep you updated.  Thanks for all the help thus far!

Whare are the distances between the router and wireless clients?

I actually e-mailed Dlink tech support, and this is what they replied with:

"Please try to unchecked auto channel scan and set a static channel. Please please channel 1, 6, 9 and 11."

AND I THINK IT WORKED..... I am still observing. So far so good!

Helllo,

I have the same problem too.
After a reboot of the router every thing workes fine, but some minutes or hours later it does not.
A Windows XP PC says nothing, just tries to reconnect.
A Samsung Galays S3 mini says authentication fault.
A Samsung Galays S3 says authentication fault.
The router is brand new (1 week in use) and the issue exists since the first day.

I have a Fritz!Box router with WLAN and DECT enabled in an other room separated by a concrete wall, but visible of course to all devices. The Fritz!Box acts as DSL modem, the DLINK is just an access point at the moment.

Any new info on that topic?
thx, Ralf

Hardware: A1
Firmware: v1.03
Location : Germany
Factory reset has been performed

>>>  Wireless Configurations  
>>>  ....
Same effect whether switching off/on or reset via web interface: Reset device fixes problem immediately but only for some hours. This means that there is no duplicated SSID or any other issue covered by "Wireless Configurations", isn't it?

btw.
This forum's account settig: Hide email address from public? has no effect in my case.
It was first unset (NO), I then changed it to YES but the mail button next to my postings did not disappear.

Seem like this could be an environment or interference kind of thing. The router works for a while then seems to stop. This is indicative to something causing the router to stop working on the WiFi.

That mode do your wireless devices support? N mode? any AC mode as well?

Hi.
I had the same problem, but only with two clients. One is computer with TP-Link TL-WN727N USB wireless card and another is HP Officejet 7500A printer. Other clients (two laptops, one with Intel PRO/Wireless 3945ABG and another with Qualcomm Atheros AR5009 802.11a/g/n wireless adapter) worked with no problem.
After initial setup and firmware update (to version 1.05) i can connect both problematic client, but after 8 hours (next day in the morning) i can't connect anymore. Only router reboot helped.
Router is on table near RaspberryPi, wireless phone and modem are approximately 1m away and the same is true for another electrical devices. Nearest router is 100m-150m (air line) away at my neighbours house. All router settings are on default values except wireless name and password (WPA mode, WPA or WPA2, TKIP and AES)
Then i set fixed channel for both bands (channel 11 in 2.4GHz band and channel 36  in 5GHz band) and mixed 802.11 g and n mode for 2.4GHz band as suggested above. After that it works, no problem with connection.
Can someone explain me why this settings worked? Isn't that something that should work out-of-the-box?

I had same issue with stock firmware (version 1.01), even after factory reset. Then i installed latest version (1.05), do a factory reset and the issue still persist. Wireless start working properly after i set what i mentioned previously.
My ISP is Ario (i think it's cable thru wireless - i have a dish outside). Modem is Thompson THG540. Connection speed is 1Mb/256kb.
I have cordless house phone approx. 1m away from router (that was i meant previously with wireless phone).
inSSIDer finds only one "router". It's a long range antenna. Signal strength is -90, channel 1, security WEP, 802.11b.

Does the cordless house phone operation on or near the 2.4Ghz or 5Ghz frequency?

Ensure PC Wireless adapter card drivers are up to date.

If you are using the 860L as an AP, did you follow this for setting it up?

First cordless phone is Philips CD 150 and it's connected to another one (Panasonic KX-TG1100FX) downstairs. Both operate at frequency range from 1.88 GHz to 1.9 GHz.

I've seen some apparent instability in 2.4GHz wireless connections to this router when I had the 2.4GHz channel width set to 20/40 MHz Auto. There's a coexistence mechanism defined in 802.11n where if the router detects other APs active using the other part of the 40 MHz channel it's supposed to stop using 40 MHz to prevent occupying too much of the band. I suspect that in some cases it flip-flops between 40 MHz on and off and causes disruptions to the wireless connections. Things seem more stable on 2.4 with the channel width set to 20 MHz.

I recommend that if users have a N mode only envrionment and client devices to support N mode only and there are other neighboring WiFi around, You can disable the HT20/40Mhz Co-existence feature and run Auto 20/40Mhz.
