Hi, I have a Dlink DSL 3782 and after a reboot, all three wireless extenders in my house cannot connect to the internet anymore.
Nothing was changed, apart from a reboot. The mobile phones all seem to be able to connect. It's just the wireless extenders that have stopped working.
If all the settings are the same, they why can't they connect anymore?
I should add the phones are only working on 5GHz, it seems the 2.4GHz channel just won't work anymore. When I switch off the 5GHz channel and try to use the 2.4GHz, the phones won't connect either.
Could it be that the reboot somehow 'broke' the 2.4GHz wireless channel?
I did not change any of the settings, I just rebooted and now the 2.4 channel doesn't work.
I have just now double-checked the settings, and they are exactly the same. Please see image attached. I just added the words 5G to the 5G channel so that I could identify which channel was working.
I also found out the 'smart TV' can't connect either, to the 2.4 channel. (It doesn't have a 5g option).
OK in any case, I will try your suggestion to reset to factory settings and try again tonight.
OK great. I will try that as well. I can send back the older one if its broken.
After the reset, the wireless is now working on both bands, but now I cannot log into the router anymore. The password on the back of the router does't work (admin/[password]), neither does admin/admin or admin/[blank].
I have read all the issues on this website about the bugs with the Dlink DSL 3782, and considering I have now spent about 4-5 hours in total trying to debug the wireless and now trying to log in to the route, I would request a replacement, if you don't mind.
Ideally not the 3782 again please.
The new router seems to be working better - wireless is stronger and no problems with connecting. Thanks for that.
The only issue I get is the internet gets slow around 3.30-4.30pm, which I think is to do with traffic generally, not to do with this router.
As there is only copper available on our street (ASDL) not fiber, then I think there is nothing I can do about the 4pm speed slump?
Around 4pm the speed has drops to almost nothing. I tried running the broadband speed checker to see the speed, however, that test could not even connect to the server to start the test.
I wonder if this is due to demand from other nearby users around that time of day?
Yesterday the speed dropped considerably, but I still have a connection. The day before, the speed dropped and I had no connection for around 5 minutes.
What could be the cause of this and any possible solutions suggested?
The sync speed looks good and the SNR isn't dropping low.
Please can you run a ping and trace route when the speed is good and another one when the speed is low (and paste results on this thread)
If you could also try running a speed test again when the speed drops using the TT speed tester (connected wired with one device)
The speed drops a lot starting 3.45-3.55 pm to about 5.00pm. (After 5.10-5.20 its back to normal. )
Here are the results of the ping test and traceroute:
It gets so slow, I cannot even get the 'broadband speed checker' website to connect to the servers to start the test.
I did the test from one wired computer.
There are other computers on our network, doing email and google docs, etc. but nothing data-intensive, and besides, the network speed is good all day every day, except between the time I listed above.
Any ideas on how to resolve this issue?
Thank you. The results do look high. Just to confirm, do you have any devices set on a timer to come on or off at this time? Are any other devices scheduled to run updates around the time that the speed drops?
