Routers have to use different 2.4 GHz channels.
If there is no interference from neigbours set one router at channel 1 and the other at 11, that way the routers do not interfere with each other, but if you have to consider neigbours then check for free channels with Wifi analyser and choose the best but always keep channels from both routers as far apart as possible.
Regarding your laptop see if you can get new wireless drivers
Ok, I get it!! The only problem is that in my building I have a crowded situation! See attachment and please tell me what should I do.
Consider that the big two I have on Channel 6 are my two routers (the big red DD-WRT network is the E3000 and the yellow Infostrada on same channel is my main router).
Regarding my Laptop, I'll check the drivers. Should it be only them?? Any other possible faults??
Thank you!

Wow that is crowded. Keep the main router at channel 6 and set the E3000 at channel 9.
Not optimal but in these circumstances the best I think
Thank you.
Yes, I'm my country everyone has its own Wi-Fi router, any apartment, any public place. We are surrounded by a lot of Wi-Fi networks.
Regarding my neighbors, today I have some strong interference also on Channel 9.
Regarding of finding the right channel, should I select the less crowded, regardless its number?
I mean...any number from 1 to 14 are ok???
Why Channel 14 it's placed with more distance from Channel 13 in the scale of the app Wi-Fi Analyzer?
Is there any reason why not to choose a particular Channel??
Channel 9 with interfere with channel 6; the max possible non-interfering 2.4 GHz US channels are 1, 6, and 11. Ch14 may technically be legal now, but few devices support it, as noted by egc.
Your lower bands are a mess, so I'd suggest 6 and 11. Or get 5 GHz... [edit: well, all of them are, from your updated info]
If its any consolation, my wife's condo has at least 4x that many neighboring signals, and some of them are nearly as strong as hers. :-/ Wish I still had a screenshot; it's almost comical.
Also makes those pics smaller, per forum rules. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

Any not so crowded channel is OK not every country has support for channel 14 and a lot of clients do not support it but if yours do then that is fine

I have quoted both as replying to both.
Thanks a lot for the help.
I'm from Italy. Where can I check for my county Channels?
What do you mean with "non-interfering 2.4GHz channels" and "lower bands are a mess" ??
I need to understand how to read these measurements I get with Wi-Fi Analyzer....
Here a screenshot from today:

Cuz your neighbors are using channels other than 1, 6, 11, or 14. See the link in my previous post; non-US is above that. Use 11 and 14, if your devices work with the latter; otherwise 6 and 11.

Nice bunny pic btw.
Wait a minute...channel interference is also when a channel has the base of its diagram intersecting the bar of another channel??
Looking at the Wikipedia link you linked me, I see that only channel 1,6 and 11 don't intersect one with each other.
Should I keep my two networks not intersected??
And what about using other channels then those mentioned?
I have discovered with Wi-Fi Analyzer that channel 2 and channel 10 are not occupied by any neighbour's Wi-Fi, but channels next to them are, resulting in having the base of the diagrams intersect widely with lots of other Wi-Fi networks.
Plus to this, I see that I could chant the width of the Channel from 20MHz to 40MHz....does that give some benefits??
Ps: no Channel 14 for me...only from 1 to 13 possible on both routers.

This is the problem w/ 2.4 GHz. The base channels span 20 MHz, which from ch6 covers ch4 thru ch8, while ch1 cover up thru ch3. This is why 1, 6, 11, are the only 14 non-interfering channels. 40 Mhz makes this worse, in this regard. If you use 40 MHz bandwidth, it bonds two non-interfering channels, so 40 MHz ch6-lower would cover ch1+ch6. This is this shouldn't be used if you have close neighbors. If you used 40 MHz, you'd need to set either ch1+upper and ch11; or ch1 and ch11-lower.
5 Ghz channels are not like this. And resize your pics to at least half that size. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

Sorry for the screenshots...corrected!
About the base channels span, what is the difference between 20MHz and 40MHz??
Actually I'm testing the mail router on Channel 3 and the E3000 on Channel 10...
In the optic of interference, I think they are ok, right? It is not necessary to place them on 1, 6 or 11 necessarily, right?
Regarding the 5GHz network, I have dedicated it to the Client Bridge between the two routers. Could I switch it and use the 2.4GHz for the bridge between the routers and the 5GHz for the laptops and devices??
Is the 2.4GHz stable for a bridge between routers?
In case, how to configure it?
Regarding my laptop issue in connecting but not having internet, I have updated the wireless Windows 10 drivers. I'll test....but I am thinking that the one I've installed were the same I had before. The setup did asked me to "repair" the driver tho... Lets see!
After some tests, I have to say that the internet connection through the E3000 is not that stable.
I often get a "No Internet Connection" page with the dinosaur in Chrome, on mine and the other laptop, and also on the cellphones I have connected with.
It doesn't happen always, but it happens often.
Is this because the bridge with the main router using the 2.4GHz network?? Will I have a better signal if I switch the bridge on the 5GHz network and use the 2.4GHz for connecting my devices to the routers??
Hey guys!
I seriously have a problem while browsing on the net when attached to the E3000 getting the DNS_PROBE_POSSIBLE or the DNS_PROBE_FINISHED_NO_INTERNET errors!!
Is there any thing I should check to understand why??
[edit: well, all of them are, from your updated info]
See the link in my previous post; non-US is above that. Use 11 and 14, if your devices work with the latter; otherwise 6 and 11.
