WAN with too many In/Out errors reason?

[hirschferkel]

Hi there,

i get a lot of errors in the reports of my WAN, does anybody know why and what to to? This is just after rebooting, the error rate grows by time...

Check your cables, switches, routers and power supplies for defects. This is likely a hardware issue, definitely not normal.

Ahm this is the statistic of the Wifi WLAN so there are no cables. What could cause so many In errors? Just the interference with other Wifis? Or is this a sign that the wireless card is damaged?

The internet WANs do not show any errors?

Best, hirschferkel

This can be normal for WiFi, but since you typed WAN I assumed a wired connection.

You can increase the transmit power of the adapter, change channels, buy a better antenna, move to a different spot where there are no other WiFis around to improve this, but these errors never completely go away, because network packets collide in mid-air with other packets, cell phone data, other types of radio transmissions and therefore get mangled.

Hi hirschferkel,

Suggestion: Check with an appropriate tool how many WiFis are around and on which channel. How many try to send on the same channel as yours resp. sending on the channel where your station is receiving. This gives you an indication how noisy is your environment. In addition to the suggestions of Franco, you can then with many wifi stations configure/adapt the channel hopping sequence or switch to 5G only or ..... You could the also detect any kind of unauthorized sender compromising your RF signal if so.

 If e.g.. you are using a 5G frequency band,  another reason could be that signal strength may be too low as this frequency is much more blocked by walls etc. you could then try to configure 2.4 band only

Wifi has as most other RF working according to standards reserved frequencies so there is no interference with other technologies like phones etc.

Piece of tin foil half a wavelength behind your antenna does wonders too.

The thing is, if i switch to channels above 11 and to a higher standard (as it was only possible to use e.g. channel 45 with 802.11g mode with PFsense), OPNsense will stop working with iPhone 5 (with channels above 11 it will automatically switch to a higher standard and not work with iPhone 5 anymore)! That's wired but we tested 2 days with all different settings and OPNsense will only work in 802.11g mode... and channel 11 was the one which is less frequented than the ones below, so we can't use 5GHz anyway...


If we try a higher standard the iPhone will not be able to login to this network and the signal strength somehow will be half the strength than in the lowest standard...

Hi bringa,

we did all these tests already, but did not get forward to a better way because we use iPhone 5 and OPNsense will not work with higher standard with iPhone5 and additionally the router in no reasonable distance anymore. So we use 2.4 band anyway...
