I have a little weird problem. I will try to describe it, feel free to ask for any additional information. I will really appreciate any help.
I have a main (primary) Mikrotik router (see signature) and secondary Asus router (WL-520GC) in my house. Mikrotik is in ground floor and Asus is in 2nd floor. Asus is only access point to help cover 2nd floor with wireless signal. Asus is connected by LAN cable to Mikrotik through home cable network.
Wireless connecting of devices to both routers is ok. In ground floor devices connect to Mikrotik, in 2nd floor to Asus. To be specific, notebook, tablet and cell phone.
The problem is with cell phone and Asus. If cell phone is connected to Asus, it discharges really fast. Usual rate is 1 % of battery per hour. When connected to Asus, it is about 5 % or more. There is no download of any data, no updates. Just connected and synchronizing incoming e-mails and whatsapp messages. When is the cell phone connected to Mikrotik, there is no problem.
I have no idea, where is the problem. The only thing I found, is this. Logging into Mikrotik and checking IP → DHCP server → Leases. There is a column Expires After. It counts from 10 minutes to 0. So I tried to connect notebook, tablet and cell phone to Asus and checked this column again. For notebook and tablet it counts down from 10 minutes to 0 and it refreshed back to 10 minutes randomly after 2, 3, etc. minutes. For the cell phone it refreshes to 10 mintues every 10 seconds.
I don’t know what does it mean. It looks like there is some weird communication between Asus and cell phone but there is no reason for it. I don’t understand it . Do you have some idea? Thanks.
Thanks. It does not help. The counter resets back to 3 days every 10 seconds although the other devices don’t (respectively these reset back to 3 days after several minutes, more or less).
Contact cell phone manufacture.
DHCP renews at 50%. So a 3 day lease should renew after 36 hours. If it is renewing every 10 seconds, you have a defective device, of you have configured your DHCP server wrong.
Device is ok, because when connected to Mikrotik, there is no problem. When connected to Asus, then there is a problem. Other devices have no problem on both routers.
Probably some specific situation. I just tried to find some possible reasons of problem. Maybe frequencies, channels, or something, but it does not make sense too much because only the cell phone on Asus is problematic.
Although, what can be wrong with DHCP server settings?
Information about Asus was in the original post. It is connected to Mikrotik. I’m here because there are smart people here with broad knowledge not about Mikrotik only. I tried to get some hints, like what to try, because there are plenty of areas where can be the problem, so some advice about direction would be nice. I’m going to some other forum though, so nobody is harmed.
I don’t know what you want from us. You said the Mikrotik is working. The problem happens when you connector the asus. I don’t use asus routers, so I can’t help with that.
That said - is the Asus configured as a router, or just access point? does it have a dhcp server running? did you disable it? Too many variables and unknowns to be much help.
. Do you have some idea? Thanks.
