FS#1041 - WZR-600DHP: Nexus 5X can not connect with HT40 + channel 1 #7991
Comments
mkresin:
Can you provide a link to the "strict specification"? To my knowledge it is perfect fine. If the channel is 1, LEDE uses ht40+ (primary-channel n plus secondary-channel n+4). If you are use one of the upper channels it is ht40- (primary-channel n plus secondary-channel n-4) |
luke-jr: I'm not sure, that's just the impression I got from #lede-dev discussion. Either way, channel 3 works, but channel 1 did not work, connecting from my Nexus 5X. With channel 1 HT40, it associates, but its DHCP DISCOVER packets are not seen by the router. |
mkresin:
Might be, but it isn't subject of the ticket... Out of curiosity, have you tried another wireless client? I can not remember to have seen such an issue with ath9k or rt2x00 hardware. |
luke-jr: At least my Raspberry Pi, Moto E LTE, and Chromebooks had no problems with it. Only the Nexus 5X couldn't connect AFAIK. |
mkresin: Have you considered that the hardware/software of your nexus is buggy? You should at least do some basic tests like connecting to AP on channel 1 with HT20, to see if there is some kind of generic issue with the nexus and the lower channels. Of course, could be that you hit an incompatibility between the wireless hardware/driver used by the nexus and the AR9223 of the WZR-600DHP. But that leads me to the next question. Why are you using the 2.4GHz wireless. The WZR-600DHP as well as the nexus are having support for the 5GHz band. |
luke-jr: Channel 1 with HT20 does work fine also. I don't know why it's using 2.4 GHz; I have the same SSID configured for both 2.4 and 5 GHz. |
mkresin: I've edited the issue title and description. Since your report is in the end about an issue with a Nexus 5X (all other of your devices are working fine). |
luke-jr: Today, I found one of the Moto E LTE is failing to connect to the channel 3 w/ HT40. Switching the router to HT20 fixed that. So it seems there's some (semi-intermittent?) problem with HT40 in general... :/ |
adrianschmutzler: Please test with recent OpenWrt and report back or close. |
