speed reduced after sonicwall installation

manish

Hi Everyone

I hope i will get the answer

So we have 1gbps dedicated static IP

we were having decent speed around 700mbps

After installation of sonic wall it drop down to 60/70 mbps

So my wan duplex =auto negation (changed from 1gbps to auto negotiation)

LAN==auto negation (changed from 1gbps to auto negotiation)

ISP router= full duplex

MTU size 1500 ISP, Sonic WAN LAN

How can i achieve maximum speed

Hello @manish , the recommendation is to verify the MTU value by referencing the following article:

https://www.sonicwall.com/support/knowledge-base/how-can-i-determine-the-mtu-size-of-wan-interfaces-manually/170504812146650/

In most cases, this should ideally fix the problem however, If that's still not working then have a look at the following list of articles.
