Hi,
I'm experiencing degraded internet connection issue, I find something strange in the log, so I want to figure out what that means first.
See the attached syslog.txt, the thing I want to focused on is the time stamps.
First, as far as I understand that the May 4-5 time stamps are before the NTP synced the time because of the lack of RTC.
What I don't understand is that if my log means that my router has rebooted a few times on its own.
Facts:
Firmware is currently on 3.0.0.4.386_49674, however I have been on 386.7_0 and 386.7_2 in the past few days.
I haven't rebooted the router today. Here's the first and last Jul 30 timestamps within each blocks of contiguous time (... are Jul 30, ...... are May):

A few questions:
Intermittent high ping and jitter with low Download speed, regardless of wired or WiFi connections.
See figure, SPEEDTEST via web-GUI, all those ping time > 100ms are anomalies. I cross-checked that with the network above mine (there's 2 subnets above me that I can't do anything about that) via WiFi at the same time of these tests, the ping continues to be ~20ms and Downloads >100Mbps. So it is definitely my router. (iperf3 between local computers continues to behave normal, achieving close to 1Gbps.)
Thanks in advance!

A few questions:
- Are the gaps of May time-stamps means the router has rebooted (on its own)? I guess so because I assume it would only shows as May if it is in the beginning of the boot process and the NTP hasn't kicked in yet?
- If so, what may have caused this problem and how may I proceed in solving/debugging this?
- May be a more fundamental question to ask is if the log is chronological? Seeing line 1021-2023:
Jul 30 01:31:58 miniupnpd[6546]: shutting down MiniUPnPd
Jul 30 08:32:00 ahs: ===Terminate ahs daemon===
Jul 30 01:32:02 kernel: eth5 (Ext switch port: 7) (Logical Port: 15) (phyId: 1e) Link DOWN.
where the time has jumped forward and back.
- All the May blocks starts with klogd started, but not all klogd started occurs in May blocks.
- All May blocks ends with ntp: start NTP update, vice versa.
Setup
- Largely followed this guide to reset: (NOOB) Definition of "minimal and manual configuration" | SmallNetBuilder Forums.
- Flashed 3.0.0.4.386_49674 firmware, other versions flashed are 386.7_0, 386.7_2. All have experienced intermittent internet connection problems mentioned below.
- Go to http://router.asus.com and follow the initial "Quick Internet Setup". Straight forward setup are followed, e.g. 2.4 GHz and 5GHz are not separated.
